In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

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

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

In this activity, learners make self-assembled polymer spheres.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

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.
