1. April 12 th and 13 th Unit 8: Space Science Open-Minded Objective(s): 1.SWBAT identify the four Galilean moons of Jupiter by their physical properties. 2.SWBAT compare and contrast meteoroids, asteroids, and comets Relevance: While we know much about the solar system, there is still a lot of unknown aspects for scientists and we must keep an open-mind when researching and learning about those unknowns. Do Now: Four-Square Do Now MATERIALS NEEDED: 1.Guided Notes 2.Pencil

2. Other Celestial Bodies Other than the planets, there are many other types of celestial bodies that are orbiting in our solar system. What other celestial bodies can you think of? Six of the eight planets have moons that orbit them including Jupiter which has four of the largest moons in the entire solar system orbiting it.

3. Moons Moons are smaller celestial objects that orbit planets. All of the planets, except Mercury and Venus, have moons. Scientists collect data about their physical properties using satellites and telescopes. What do planets orbit? What do moons orbit?

4. Galileo Galilei During the 1600s, Galileo Galilei discovered four large moons orbiting Jupiter using a telescope he made. At the time, these were the first moons ever found orbiting a planet other than the Earth. These four moons are now known as the Galilean moons.

5. Why are the four largest moons of Jupiter known as the Galilean moons? Stop and Jot

6. Galilean Moons The Galilean moons are four of the six largest moons in our solar system. In order of their distance from Jupiter they are called – Io, Europa, Ganymede, and Callisto. What are the four Galilean moons called?

7. Io Io is the closest Galilean moon to Jupiter. It is the most volcanically active body in the entire solar system. It orbits Jupiter.

8. Europa Europa is the second Galilean moon from Jupiter. It has an icy surface that likely floats on top of a liquid ocean. The ocean underneath these blocks of ice is an environment that could support life forms.

9. Ganymede Ganymede is the third Galilean moon from Jupiter. It is the largest moon in the entire solar system – even larger than Mercury!

10. Callisto Callisto is the fourth Galilean moon from Jupiter. It is the third largest moon in the solar system. It is also the most heavily cratered body in the entire solar system.

12. Other Moons Titan is the second largest moon in the entire solar system – it orbits Saturn. Composed primarily of ice and rocky material. The only moon known to have a dense atmosphere.

13. Other Moons Our moon is the fifth largest moon in our solar system. The surface is thick with dust and rocks. There is no water and no atmosphere.

15. Asteroids, Meteoroids, Comets The solar system contains other objects than moons and planets. Some of these objects include asteroids, meteoroids, and comets.

16. Asteroids Asteroids are the next largest objects in the solar system after moons. Asteroids are rocky bodies that revolve around the Sun. Asteroids vary in shapes and sizes but are mostly made of iron, nickel, and stone. Most asteroids in the solar system can be found between Mars and Jupiter – this is called the asteroid belt.

17. Meteoroids, Meteors, and Meteorites Meteoroids are stone-like or metal-like material that travel through space. They may have been formed from collisions between other bodies in the solar system or parts of planets.

18. Meteoroids, Meteors, and Meteorites When a meteoroid strikes the Earth’s atmosphere, they burn up in bright streaks and become meteors. If a meteor survives and hits the ground, it is called a meteorite. What is the difference between a meteoroid, meteor, and a meteorite?

19. Comets Comets are icy bodies that release gas or dust when heated. Comets’ orbits are long, narrow ellipses – more elliptical than any other orbit. They spend a very short amount of time near the Sun before swinging out beyond Pluto. They are usually very hard to see, but as they approach the Sun, they begin to release gas and dust and are lit up by the sunlight to form huge tails.

23. Is there a possibility that there could be life elsewhere in the solar system? Think-Pair-Share

24. Solar System BINGO Each scholar has a different BINGO card. I will read the clues for different types of celestial bodies in the solar system or various vocabulary words. Silently use your notes to identify the word and mark it on your BINGO card. We will talk about the word before moving on. 20 min

25. Independent Practice RAFT Activity Role Role: Travel Agent Audience Audience: People who want to travel to outer space. Format Format: Travel Poster Topic Topic: There are people interested in moving to outer space to live. Create a poster to present to them. 25 min
