This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.

Use this hands-on activity to demonstrate infrared and thermal radiation.

Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.

Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.

This activity features two connected hands-on activities about dinosaur bones.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
