In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

In this activity, learners design and build a toy top out of simple, everyday materials and have the option to use the toy as an artistic tool.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

In this activity, learners investigate how some butterfly wings get their color.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this demonstration (9th on the page), learners explore eyewitness memory and how memories differ amongst individuals. While the rest of the group is minding their own business (i.e.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.
