Lead a discussion about asteroids and their physical properties, then have students mold their own asteroids out of clay.

In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. They will then determine whether sea-level rise is occurring based on the data.

This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat being trapped on our warming world.

Students create a scale model of the solar system using beads and string.

Students use global temperature data to create models and compare short-term trends to long-term trends.

Students will use the engineering design process to design, build, test and improve a model satellite intended to investigate the surface of a planet.

Students predict the scale of our solar system and the distance between planets, then check their answers using fractions.

Using real data from NASA’s GRACE satellites, students will track water mass changes in the U.S.

Students explore practical applications of exponents and division to investigate what it takes for NASA spacecraft to travel deep into the solar system using only solar power.
