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

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

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, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

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 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 (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

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

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.

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

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

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.

In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.
