In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

What keeps bubbles and other things, like airplanes, floating or flying in the air?

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 construct a cereal chain as a model of how proteins are made in the cell.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this health activity (page 6 of the PDF), learners examine ingredient labels of packaged food products to find out what sugar ingredients they contain.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

Learners examine what happens when a tube spins in two directions at once. They push on a cardboard tube causing it to spin along its length while at the same time turning from end-to-end.

In this physics activity (page 8 of the PDF), learners will explore the concept of inertia by attempting to run and stop quickly.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

Learners make their own simple slide rules out of paper and learn how they work.
