They will "stargaze" and drag stars to the galaxy to see what could be in our solar system. They will learn a mnemonic to remember the planets in order from the sun: "My Very Energetic Mother Just Served Us Nachos." They will discuss how big the planets are and talk about an effect that can make things that are very large appear small. They will put their thumbs up to a larger object, such as a clock, and slowly walk backward. They will discuss that at a certain point, their thumbs covered the clock and that the size of the clock didn't change, but their distance from it did. They will transfer this knowledge to the solar system.
Students will discuss the amount of time it takes for a planet to make a rotation on their axis (a day) versus the amount of time it takes to make one trip around the sun (a year). They can also see how their age changes on other planets in our solar system. Students will discuss how gravity affects their weights on different planets.
The first four planets, or the inner planets, are Mercury, Venus, Earth, and Mars. Students will read about some facts about each planet, including their size, number of rings, number of moons, and the length of a day/year. They will then answer some questions about what they learned about the first four planets.
They will also talk about the asteroid belt, a region between the orbits of Mars and Jupiter. The next four planets, or the outer planets, are much larger. They are Jupiter, Saturn, Uranus, and Neptune. Students will read facts about these planets as well. They will then review the mnemonic they learned at the beginning of the lesson.
