In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

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

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

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

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

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

Get all wrapped up in a lesson about skin!

In this activity, learners explore Charles' Law in a syringe.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
