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

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

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

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

In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

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

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

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).

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

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

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

This Exploratorium activity explores size and scale. Through four levels of screen sizes, learners can sort out objects of different sizes.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
