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

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this activity, learners examine nanoscale structures of common things.

In this activity, learners make a model of a beehive using simple materials.

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

Build and test a scale model of a rainforest canopy walkway.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

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.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
