In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners make balloon models of disease-causing bacteria.
