Potion Commotion
Source Institutions
In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

Volcanic Material Catapult Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

Operation Espionage
Source Institutions
In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.

What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.

Crocodiles
Source Institutions
Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

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.

Grow Rock Candy
Source Institutions
Learners grow sugar crystals (rock candy). They make a hot solution that has an excess of sugar dissolved in it, then as the solution cools, they see sugar crystals form.

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

Chemical Methods of Control
Source Institutions
In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

Piezoelectric One-Way Remote
Source Institutions
In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.

Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

Instant Ice
Source Institutions
In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.

How Many Pennies?
Source Institutions
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Meltdown
Source Institutions
In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

Layered Liquids: Chemistry You Can Drink
Source Institutions
In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

DNA Extraction: Look at your genes!
Source Institutions
Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

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

Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.
