Students learn about the role of dark energy and dark matter in the expansion of the universe, then make a model using balloons.

Students use simple materials to model a partial, annular, and total solar eclipse.

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

Students develop spreadsheet models that describe the relationship between the mass of a spacecraft using electric propulsion, the force acting on the spacecraft, and its acceleration.

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.

Students build a spectrometer using basic materials as a model for how NASA uses spectroscopy to determine the nature of elements found on Earth and other planets.

Students build a model that demonstrates an important contributor to sea-level rise – how water volume increases when the temperature of the water increases.

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.
