In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

In this activity, learners explore the different heating properties of soil and water.

In this "Sid the Science Kid" activity from Episode 108: My Ice Pops, learners observe reversible change while thinking about ways to make ice melt.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

In this activity, learners demonstrate the effects of cold-working (strain-hardening) and annealing. Learners discover that these processes change the load that a wire can support.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners investigate why apples turn brown. Learners discover that lemon juice interferes with the reaction that causes the browning.
