Students build a scale model of the solar system that represents the size of each planet as well as their distances from one another. Questions: Why are the planets spherical in shape? How big is the Sun in relation to the largest planets in the solar system? In the scale model, what object might be used for the Sun?

In the activity, students use their bodies and movements to help them understand concepts (like which direction the Earth rotates and when sunset and sunrise occur) and locations (like where the equator is). Questions: Why do people in different locations, looking at the sky at the same time, see different things? What does the Earth's rotation have to do with days and nights on Earth?

Students use a kinesthetic activity to better understand how the tilt of the Earth relates to changing patterns of light and the change in seasons. This lesson addresses common misconceptions about the relationship between the seasons and the Earth's position in relation to the Sun.  Questions: At what time of the year is Earth closest to the Sun? How is the angle of the Sun's rays that reach the Earth related to the season?

Share a story about traveling in space, like A Long Way Away by Frank Viva or Mousetronaut Goes to Mars by Mark Kelly. Also read together “What Would You Pack for a Trip to Outer Space?” on Wonderopolis. Inform students that they will all be taking a trip to Mars, a roundtrip journey that will last three years, including travel time and exploration of the Martian surface. Together, create a list of different categories of supplies that students may want to consider (e.g., food, hygiene, science equipment, safety, etc.). Then divide students into groups to list all the things they will need to have to survive the trip. After groups have created their mission supply lists, share supply ideas with everyone. Discuss what items were frequently overlooked, which are absolute necessities and which are for personal comfort. Talk about the amount of careful planning that goes into space missions to ensure that astronauts go into space — and return — safely.
