Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Life in the Sidewalk Cracks
Source Institutions
In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

Forward-Reverse Switch

Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

I Spy Nano!
Source Institutions
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.

Design a Seed
Source Institutions
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.

Bent Toward Science: Refraction
Source Institutions
This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

Eyewitness Game
Source Institutions
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.

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

Egyptian Measuring
Source Institutions
In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.
