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

In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

This reading and writing activity (on pages 2-9) teaches what plant parts should be avoided, how a person can get rid of toxins, symptoms of plant poisoning, and how plants create poisons to repel pre

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this matchmaking activity (on page 2 of the PDF under GPS: Animal Scent Activity), learners will each have a scented cotton ball taped to their shoulder. The scent (e.g.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.
