This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this activity (on pages 24-34), learners explore the four-part stomach of cows (and other grazing animals called ruminants), and compare it to the human one-part stomach and its digestive process.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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 activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

This activity (on page 2 of the PDF under SciGirls Activity: Pet Handedness) is a full inquiry investigation into whether pets show a preference for the left or right paw, or “handedness” like people.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this water activity, learners discover ways to move water across the water table.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this activity, learners investigate the olfactory system by conducting several experiments.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.
