Where is the Sun?
Source Institutions
In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.

Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.

Rusty Penny
Source Institutions
In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

Where Are the Distant Worlds? Star Maps
Source Institutions
This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

Electrical Fleas
Source Institutions
In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.

The Shape of Floatation
Source Institutions
In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

Make Your Own Sculpture Dough
Source Institutions
In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

Paper Cover Up
Source Institutions
In this activity on page 11 of the PDF, learners use candle wax to make "invisible" designs that are revealed with watercolor paints.

Ramps 1: Let it Roll!
Source Institutions
In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.

Absorb & Repel
Source Institutions
In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.

Amazing Albedo
Source Institutions
In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

Newspaper Collage
Source Institutions
In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.

Rollback
Source Institutions
In this physics activity (page 10 of the PDF), learners will make a can that will roll back after it has been rolled away to observe the interactions of kinetic and potential energy.

Fingerprint Identification
Source Institutions
In this crime science activity (on page 2 of the PDF), learners will explore the uniqueness of fingerprints. The will learn components of fingerprints as well as why fingerprints are left behind.

Drying It Out
Source Institutions
In this activity, learners investigate and compare the rate of drying in different conditions.

Separating with Chromatography
Source Institutions
In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").
