In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners confront their perceptions of gravity in the solar system.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Learners develop an understanding of air pressure in two different activities.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners examine the culture and history of the tomb site.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
