Chain Reaction II
Source Institutions
In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

Make Your Own Pendulum
Source Institutions
In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

COSI Quicksand
Source Institutions
In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?

Rubberband Rollback
Source Institutions
In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

Cookie Paleontology
Source Institutions
In this activity, learners will explore paleontology and archaeology. They will learn about technique as they excavate raisins and chocolate chips from cookies.

Magnetism Hunt
Source Institutions
In this activity about magnetism (page 4 of the PDF), learners will experiment with magnets and different objects to find out that not all metals are attracted to magnets.

Magnetisphere
Source Institutions
In this activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.

The Pressure's On
Source Institutions
In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

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.

Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways

Applying Math to Astronomy
Source Institutions
In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.

Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

Edible Soil
Source Institutions
In this yummy activity about soil (page 9 of PDF), learners will create layers of soil using food. They will learn about the composition and role of each layer.

Paper Cup Anemometer
Source Institutions
In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

Balloon Rockets
Source Institutions
This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

Which Foods Contain Sugar?
Source Institutions
In this health activity (page 6 of the PDF), learners examine ingredient labels of packaged food products to find out what sugar ingredients they contain.

Homemade Rube Goldberg Machine
Source Institutions
In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

Hang Time
Source Institutions
In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.
