In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

Learners use shop tools and various materials to construct a magnetic spinner and a compass.

In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

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 construct a device that allows them to view 2-D images in 3-D.

In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this activity, learners model ancient lunar impacts using water balloons.

In this activity, learners explore sports engineering and advanced materials development.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

In this Bob the Builder(TM)-themed activity, learners explore the 3Rs (Reduce, Reuse, Recycle) by rotating through several activity stations.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.
