In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

In this electrochemistry activity, learners will explore two examples of electroplating.

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

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

In this activity, learners explore how musical instruments are engineered.

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this outdoor activity and/or field trip, learners investigate the behavior of hopping animals.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
