In this activity, learners explore the concept of conducting or insulating electricity.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners explore how boats are engineered to achieve speed.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

Using simple, inexpensive items, learners build and test submarine models.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this activity, learners use simple items to construct a device for indicating air pressure changes.
