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.

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.

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

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.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

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

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this activity (18th on the page), learners conduct an experiment to examine memory.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.

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.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.
