In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this activity, learners drop impactors onto layers of graham crackers!

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

This simulation helps learners understand what happens to food as it passes through the digestive system.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.
