In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

This lab activity has learners create a pendulum with a one-second period.

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

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

In this activity, learners are invited to imagine the park of their dreams!

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

In this activity, learners explore how mirrors reflect light and change the way we see things.
