Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

This demonstration activity models how Venus appears from Earth.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

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

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this physics activity, learners will investigate the strength of egg shells.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.
