1.Concept Map:
2.South Carolina Standards which are relevant to WebQuest 4 are in the attached lesson plan.
3.Essential learning from Support Documents (Grade 8 Science) is also included in the lesson plan which accompanies this blog.
4. Through this WebQuest the students will work in small teacher-selected groups through a series of inquiry- based tasks. Each task will build on the previous task and will promote collaborative work in setting a group goal and working together to attain it.
The resources which I selected were chosen for their high degree of color, movement, invitation to interaction, multimedia options, and scientific reliability. Even the students who lack knowledge of NASA and lunar science should find the WebQuest stimulating and easy to navigate. The Group products will demonstate collaboration and encouragement from student to student, and from teacher to individuals and to the group.
5.Some students have little idea of NASA's past, present, and future missions. Some may feel that space exploration is a luxury which we can no longer afford. I hope they will come to realize, as I do, that our country cannot afford to let our space missions lapse. Other countries will not be complacent, instead moving forward as we fund wars instead of the exploration of space. Of course I want the students to form their own opinions and reach their own conclusions as to the necessity of keeping space exploration in the forefront, rather than on the back burner. The final space shuttle launch in July, 2011 will spur discussion of this topic. I feel that the WebQuest lesson will enable the students to speak with scientific knowledge as their guide through thoughtful introspection of the topic.
6. I learned many new things from the construction of this lesson:
purpose and goals of a Web Quest
how a WebQuest connects concepts
cross-linking of ideas
encouraging tolerance of divergent views
concept mapping as a group goal
7.What type of global partnership is involved in the Chandaryaan Mission?
The European Space Agency, China, Japan, India and NASA (United States) all woked together on India's fist foray into space exploration.
When will the M3 Mission goal of mapping the entire Moon surface be met?
The Chandaryaan-2 Mission will begin in 2013. It will utilize the mapping information that has been returned to Earth by M3 since its launch in 2008 and will continue the task of mapping the lunar surface.
8.Through the development of WebQuest 4, I learned how to construct a high-interest inquiry-based lesson which is adaptable to a variety of learning styles and student background levels. The value is in the process of research, not just the products the groups will produce and demonstrate at the conclusion.

Lesson Plan
Students will analyze and compare the purposes of scientists' tools and technology utilized to study space.
Students will compare the wavelengths and energy of waves in various parts of the electromagnetic spectrum.
Webquest 3
Task #1
A. It lights up. It is far away from the Earth. It is big and has dark spots. It is grey and cold.
B.1) What is its source of light? Does it make its own light?
2) How far away is it?
3) Why does it look different throughout a month?
C.1) How did NASA scientists ever figure out how to get to the Moon?
2) What did we expect to find out about the Moon before we sent unmanned spaceships there?
3) Where are all of the Moon samples and what did they teach us?
Task#2
I selected two unmanned missions because these allowed the Apollo astronauts to later travel there. Both are in the Surveyor series of Lunar Missions that took place during the 1960s. This was a time of nervous excitement and anxiety over the space race with our Cold War rival USSR.
Surveyor 1 ( launched May 30, 1966, landed June 2, 1966) wa the first U.S. spacecraft to land safely on the Moon. It returned 11,240 photographs and lasted for two lunar days. It landed in the Ocean of Storms at 2degrees 28minutes 45.59 seconds S and 43 degrees 20minutes 28.92 seconds W
Surveyor 7 (landed January 10, 1968) was the fifth and final spacecraft of the Surveyor series. It landed in the highland region near Tycho: a large lunar crater which is visible with the naked eye from Earth. It returned 21, 038 images and more than 100 hours of surface composition data. Landing site 40 degrees 51minutes 36.49 secondsS and 11degrees 28minutes 12.57 secondsW
Task #3
My mission to the Moon is called Selene (after the Greek Moon Goddess, and meaning Spark Extra Learning and Encourage New Exploration). After selecting this name from mythology, I found that the Japanese have used Selene as part of the name of their recent mission. I think they made an appropriate choice. Hopefully through interesting lessons and with an increased government interest in exploring space, we can challenge the next generation of scientists.
1. The Lunar Mission will be robotic. As is evident in the Concept Map, the planning and funding for a robotic mission are significant. Within the current economic times, I doubt that a manned mission could be on the horizon for NASA, but in the future, we can hope....
2.The spacecraft will be landing on the surface of the Moon at the Aristarchus Plateau (20 degrees 55 minutes 03.30 secondsN and 58degrees 48 minutes 39.48 secondsW) where large pyroclastic deposits will be studied. Their composition offers telling insight into the make-up of the lunar interior. Pyroclastic ash could be useful if the Moon is ever inhabited by humans.
3.This geographically diverse region will lend itself to many scientific experiments and it is close to resources which could be used by future lunar settlers. * when I was a child we had television shows, books, and even cartoons(the Jetsons) about living on other planets.
4. Goals: to photograph ancient rocks to help prove the theory of collision
to reignite public interest in and Congressional support for the space program
Sadly, on this 50th anniversary( May 25, 2011) of President Kennedy's address to Congress in which he said, "We intend to be first...to become the world's leading space-faring nation...We have a long way to go in this space race. But this is the new ocean, and I believe that the United States must sail on it and be in a position second to none."
From USA Today (5/25/11)
Apollo Astronauts Neil Armstrong, Jim Lovell, amd Gene Cernan authored an article stating that,"Kennedy launched America on that new ocean. For 50 years we explored the waters to become the leader in space exploration. Today, under the announced objectives, the voyage is over. John F. Kennedy would have been sorely disappointed."
All 3 of these astronauts commanded lunar missions. Armstrong was the first human to reach the lunar surface and Cernan was the last to leave it.5. Quite a few science instruments will be utilized including: television camera
bar magnets
horseshoe magnets
spectrometer
video and radio communications
mirrors
cameras
magnetometer
6. Yes, the mission will employ an orbiter to communicate with Earth through pictures and computer images which are translated and enhanced.
7.NA/ Due to current budgetary constraints this will be a robotic/unmanned mission.
8.No, there will be no way for the lander to launch from the Moon. The images will be so spectacular and new that the mission will stimulate Congress to allocate funding for the continued exploration of space.
Task#4
The Lunar Mission Selene is named in deference to the ancient astronomers who made bold predictions in the face of scepticism and queries, laughter and criticism. The Greek Moon Goddess Selene is a link from then to now, and to those who will study space in the future.
In the 1600s Kepler made a prediction that must have appeared as unbelievable," As soon as somebody demnstrates the art of flying, settlers from our species of man will not be lacking... Given ships or sails adapted to the breezes of heaven, ther will be those who will not shrink from even that vast expanse.Therefore, for the sake of those who... will presently be on hand to attempt this voyage,let us establish the astronomy, Galileo, you of Jupiter, and me of the Moon."

Task 1
The detailed explanation defining light and its sources is helpful to me as a teacher, and it will be a powerful tool to build knowledge for my students.Exploring the electric field of light and the resulting magnetic field will enable students to evaluate the variances among light waves by examining how they travel,posess energy, and can be broken into patterns called spectra. Remote sensing is interesting and exploration of it will be like puzzle being solved by my students.
Task 2
1.Magnesium, sodium, and oxygen are in the sun's spectrum. It is composed mostly of hydrogen, as well as some helium,magnesium, and iron.
2.As light passes through the cooler outer layers of the sun, some of the light is absorbed,resulting in dips in the spectrum graph. Evaluation of this graph enables astronomers to identify which elements are present in the sun. As far back as the 18th century astronomers utilized spectroscopes to determine that space objects are composed of the same elements as Earth.
1.Anorthite 43%, Olivine 16%, Ilmenite 41%
Anorthite is a member of the plagioclase group. It is rich in calcium and exhibits twinning.
Olivine is an essential rock-forming mineral of basalt, gabbro,and peridotite.It is often present with pyroxenes, plagioclase, feldspars, and magnetite. Olivine has a granular appearance,a glassy luster,and is green in color.
Ilmenite is sometimes present in veins or large masses as a product of magnetic segregation within metamorphic rocks. Most often it is present as an accessory mineral in igneous rocks and in beach and river sands.
2.I enjoyed the Lunar Experience and the comparison to the Synthetic Lunar Mare Basalt.I did not look up the answers, but played it as I would want the students to do. Interactive exercises like this stimulate the young mind and show direct correlation to Mathematics.Changing one variable immediately affects another, which is a foundation principle in scientific inquiry.The presence of chemical formulas and links to definitions and descriptions show students how to be scientists, to conduct research, and to presnt the results of their research as scientists would(in tables and graphs).
Task 3
1. This is a picture of my spectrometer.
2. This is a photograph showing the spectrometer in use.
3. A spectrometer is a device which will break light into a spectrum (light's collection of component colors). The spectra are different for each element, enabling identification of elements through spectra observation. Astronomers gain useful information by using spectrometers.
The light coming from the object is filtered into a thin sliver of light which hits a prism, splitting the light into spectral lines of color. The spectrum is reflected off of mirrors until it reaches a flat surface where the spectral lines can be identified by wavelength.The wavelength depends on what color it is(red has a higher wavelength than blue).
Task 4
Figure 31.This image of the Moon from the orbiting ROSAT Observatory shows the bright hemisphere, the darker half of the Moon and the sky background.The bright hemisphere of the Moon shines due to the fact that it scatters x-rays emitted by the Sun.
2.The dark side shadows background radiation from deep in space. The background sky is a little lighter due to other galaxies in the distance.
Figure 4
1.The Sun is shining on the left side of the Moon, which is why that side is brighter in radio wavelengths.
Figure 5
1. Image 1,2,and 3 appear to be the Moon viewed from the exact same location with a variety of wavelengths affecting the coloration. The Maria and craters are visible in all 3 photos, but their clarity is enhanced in the ultraviolet and visible examples. The darker regions, which look round, and the bright spots are usually small.The visible, with which we are all most familiar, is the most "comfortable" to view, but the others bring heightened interest as to what new information they can provide. The fourth view(near-infrared) is wildly colorful and an interesting puzzle to analyze. The vivid colors can be utilized to place emphasis on what is being examined or studied. The jagged edge as it cuts to darkness in the upper right quadrant provides challenge and questions.This is probably an image taken from space and at an angle which we cannot see from Earth.
2. Patterns of Moon features are concurrent in all 4 views. The variance is the color emphasis provided by a variety of wavelengths. Many colors were used for each image.
3. The maria are most visible in frames 1 and 4, less visible in 2 and 3. Despite this frame 2 is most like we see the Moon with the naked eye, so this frame is comfortable and clear.
4. A variety of light sources can be utilized to place emphasis on certain features which are being examined and studied. Young children will be most interested in the images utilizing color.
Figure 6
5. These images show the actual terrain of the Moon: the Maria, craters, and highlands. They appear to be 3 dimensional, and a closer view.
6. Many colors are used for each image. Apollo 8 photographs show the Earth as blue-grey and white when viewed from space. Neil Armstrong stated that the closer they got to the Moon, the colors faded. We look up through the atmosphere at the Moon. It is illuminated by the Sun.7. Colors are a product of viewing the Moon through the atmosphere of Earth and distortion occurs. The colors are distorted by the distance. Photos taken by Apollo 17 show blue-green rather than grey.
7. No, these are not the real colors of the Moon. The colors are coded to specific fingerprints of brightness of reflected light. The various colors represent regions that are bright at different wavelengths of light, so a variety of colors indicate that the parts of the Moon are composed of differnet minerals.

1. Concept Map emailed to Cynthia Hall.
2. Relevant South Carolina State Standards for Grade 8: Science 8-4.4,8-4.6, 8-4.10,8-6.7 and 8-6.8. Math 8-5 measurement, 8-6 data analysis, 8-4 geometry
8-4.4 Explain the motions of Earth and the Moon and the effects of these motions as they orbit.
8-4.6 Explain the effects of gravity on tides and planetary orbits.
8-4.10 Compare the purposes of the tools and the technology that scientists use to study space (telescopes, satellites, space probes, spectroscopes)
8-6.7 Explain how the absorption and reflection of light waves by various materials result in the human perception of color.
8-6.8 Compare the wavelength and energy of waves in various parts of the electromagnetic spectrum.
3. Students must understand the following concepts:
8-1.1 Be able to design a controlled scientific investigation.
8-1.3 Make an inference to form a valid conclusion.
8-4.4 Explain the motions of Earth and the Moon and the effects of these motions as they orbit.
8-4.6 Explain the effects of gravity on tides and planetary orbits.
8-4.10 Compare the purposes of the tools and the teachnology that scientists use to study space.
8-6.8 Compare the wavelength and energy of waves in various parts of the electromagnetic spectrum.
It is essential for the students to know:
A day is based on the 24 hours that it takes Earth to rotate on its axis counterclockwise from west to east.
A year is based on 365.25 days it takes Earth to revolve around the Sun in an elliptical orbit.
The Moon revolves with Earth around the Sun as the Moon is revoving around Earth.
The Moon revolves around Earth in 29.5 Earth days.
As the Moon revolves(similar to Earth) it is rotating and spinning on its axis.
The rotation time for the Moon is a little more than 27 Earth days.
Because the Moon rotates and revolves in nearly the same amount of time, the same side of the Moon always faces Earth.
Refracting and reflecting telescopes collect visible light, then use convex lenses or mirrors to focus the light and produce larger, brighter images of distant objects in space.
Radio telescopes receive radio waves emitted from objects in space, including waves from very distant stars and galaxies.
Other telescopes "read" infrared or x-ray signals, but must be placed where Earth's atmosphere does not block or absorb the signals.
Satellites are placed in orbit around Earth with special instruments and telescopes which collect information from space. The information is then sent back to Earth where it is interpreted.
Data gathered from satellites is not hindered by Earth's atmosphere.
Space probes contain instruments to collect data and travel out of Earth's orbit to explore places that would be too dangerous for astronomers.
Spectroscopes collect light from distant stars and separate that light into bands of different colors. By studying these bands, astronomers identify elements.
4. Students can make scientific observations and inferences by conducting experiments like making a spectrometer and using it. The simle project which we did utilizes common household items to make a tool that real scientists employ every day. It links to mathematics through geometry and the recording of data. Inferences are made about repeated trials, and predictions will follow. Curiosity will prompt further questions, and the cycle of learning continues.
5. Many students will arrive with rudimentary knowledge of what a spectrometer does, but will have questions about how modern scientists and ordinary people use this instrument to acquire information about Astronomy. Because we live near the beaches, where nights are dark, the students can be encourged to look skyward in the evening and question what they see. In the daytime they can utilize the spectrometers they have made to delve further into scientific investigation to answer their inquiries.
6. Sir Isaac Newton identified that a glass prism split sunlight into a rainbow of colors, naming this a spectrum(from the Latin word for ghost). If visible light strikes gas molecules as they pass through the atmosphere, the light gets absorbed as energy. Higher energy blue light is absorbed more often than lower energy red light. Red is iron abundance near poles and in ll mare regions of the Moon.
Upon reaching the lunar surface Astronaut Irwin noticed a large boulder that looked green(tiny spheres of green glass). Were they frozen remnants of a fire fountain eruption from 3.5 billion years ago?
Red is hot temperature, blue is cold temperature, while white, yellow, and orange fall between the two. Scientific instruments are able to discern small variations in color.
I learned that distance from the Sun and atmospheric composition affect the temperature. Earth and Moon receive approximately the same amount of heat from the Sun, but the Moon lacks the atmosphere needed to retain much of that heat. The Moon has a very thin atmosphere composed of gases vented from the Moon's interior and particles of solar wind.
7. What is albedo? It is a measure of the reflectiveness of a celestial body, expressed a s a percentage of the amount of sunlight that it reflects back into space. Earth's albedo is 38%, while the Moon's albedo is 7% (12% in another source). Albedo has a large influence on surface temperatures.
How is electromagnetic radiation emitted? It is emitted along a range of wavelengths. Radiation is electromagnetic because it moves as interlocked waves of electrical and magnetic fields.
8. I learned about a variety of games at the NASA Education website. These interesting and simple games will enhance my students' learning in an enjoyable way. These can be accessed from home or school, and the links can be placed on my eChalk page for easy accessibility for students and parents. They can be utilized for extra credit or for buiding knowledge in students who are absent from school.

2.Two shadows can be parallel with a single light source, even though they may not appear to be parallel. Sunlight is bouncing back from the lunar surface.
This was sent via email to Cynthia Hall due to an inability to transfer it from Inspirartion into the Blog.
The Moon revolves with Earth around the Sun, but the rotation for one complete spin of the Moon is a little over 27 Earth days.

They are able to explain how technology and computer modeling have increased our understanding of the Moon.
From South Carolina State Department of Education Science Support Documents Grade 8
Design a controlled scientific investigation. Determine the effect of an independent variable in an experiment when all other variables are controlled. Every controlled scientific investigation provides information(data). Data includes both scientific observations and inferences.
Identify a testable question
Research information
State the hypothesis
Design and experiment
Conduct the experiment and record data in tables, graphs, or charts
Analyze data to figure out what it means.
A scientific investigation that is conducted accurately: Using appropriate tools safely safely and accurately, Making careful measurements, Using mathematical formulas appropriately, Representing numbers with appropriate units of measurement, Recording data in organized tables, graphs, or charts
Inferences are sometimes needed to help form a valid conclusion. An inference is an explanation of the data that is based on facts, but not necessarily direct observation.
Questions that can help decide what further investigations may be: Can the procedure or product be improved? What would happen if another independent variable were tested? What are you wondering now?
Day, year, phases of the Moon and the efffect of these motions
The moon has a greater effect on Earth's tides than the Sun because it is closer to Earth. The gravitational pull between Earth and it's Moon causes distinct mations between them.
The Moon being closer to the Earth than the Sun(distance) has the greatest pulling effect on tides.
The Sun also pulls on Earth and can combine its force with the Moon causing even higher tides(spring tides) or can be at right angles, pulling against the Moon's pill, causing very little tidal change (neap tides).
Weight can change if an object is located on another object in space, for example the Moon or Mars.
Astronomers use telescopes, satellites, space probes, and spectroscopes to make observations and collect data about objects in the solar system and outside of the solar system. These tools and the associated technology that allow astronomers to analyze and interpret the data help scientists learn about the solar system and the universe.
4. A variety of activites and games, especially the marbles in the flour and flashlight with ball, will create interest and enhance understanding of the Moon, why we went there, and hope to go again. These can be adapted for a variety of grade and knowledge levels. Larger groups with assigned jobs for each student would be effective in Middle School classrooms.
5.Many students, and unfortunately some adults, have misconceptions about the Moon emitting its own light, that it is not up during the day, that Earth's shadow causes Moon phases, and that the Earth protects the Moon from meteorites. There are also links to some religious and belief systems, with Doomsday predictions for 2012.Without overtly contradicting students' religious beliefs, our job as educators is to show them the scientific data that exists, and help them to become scientists.We strive to awaken curiosity and foster a love of research through the use of hands-on modeling, virtual and actual field experiences, examining photographs and videos, and playing games to provide intellectual stimulation. Our goal is to make the students want to learn more and provide them with the tools to do so.
6.I learned, or actually relearned, many properties of the Moon that I had forgotten. Rocks and minerals of the Moon, its formation, comparisons of the Earth and the Moon, and seismic activity on the Moon are a few of the things that interest me and challenge me to learn more. I remembered the large temperature swings, but not the duration of a night on the Moon. Interactive games and use of spectrometers, as well as the previously mentioned activities, will help to dispel myths about the Moon.
7.What are NASA's latest findings about the Moon? The Lunar Reconnaissance Orbiter is releasing new images and maps; the far side of the Moon is shown.Why do South Carolina high school students have to take an elective course to learn in depth about Astronomy? State Standards emphasize courses in the basic sciences: Biology, Chemistry, and Physics. These are the classes for which End of Course Tests are developed and administered, leaving many areas of Science, including a study of Astronomy, to be taken only by a limited number of students.
8.My favorite activity of the weekend was the Projectiles in the Flour, and I believe this will be useful for a variety of group sizes and grade levels.Follow-up can be drawing and labeling what you have seen, then viewing actual photographs of the Moon from the NASA site. A writing activity of comparison and contrast could lead to production of a Powerpoint in which the students would include pictures and videos related to lunar investigation.
