Good Vibrations
Source Institutions
In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.

Sticky Snot
Source Institutions
In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

Wetland Filter Model
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

Sustainable Fishing
Source Institutions
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.

Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

A Tree of Genetic Traits
Source Institutions
Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.

Population Game
Source Institutions
In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can
Balance Challenge
Source Institutions
In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

Observing Different Microbes
Source Institutions
In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.
