Learners manipulate opaque, sealed boxes and attempt to determine their interior structures. Each box contains a moving ball and one or more fixed barriers.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

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.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this activity described on pages 2-3 of the PDF, participants debate whether there there's life elsewhere in the universe.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.
