In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

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

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this adapted version of poker, learners practice writing chemical formulas by playing this chemistry card game.

In this activity, learners investigate circulation and measure their own your heartbeat. A heart rate, or pulse, is the number of times the heart beats per minute.

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity (on page 2), pairs of learners create an imaginary crime scene. One person leaves the room while the other person moves a few things around.

In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

In this activity, learners explore sublimation by conducting experiments with dry ice.

In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).
