Rainbow Density Experiment
Source Institutions
In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

Build an Electromagnet
Source Institutions
In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

Candy Dish Natural Selection
Source Institutions
In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

Catch the Wind
Source Institutions
In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

Pulleys
Source Institutions
In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

Owl Pellets
Source Institutions
In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.

Bones
Source Institutions
In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

Doppler Effect
Source Institutions
In this activity, learners use a tuning fork to explore how the Doppler effect works.

Chocolate Lava
Source Institutions
In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

Reducing Friction-Build a Hovercraft
Source Institutions
In this activity, learners learn about friction by making their own miniature hovercraft.

Magnet Races
Source Institutions
In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.

Build a Rocket - and a Launch Pad!
Source Institutions
In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Making Sodium Acetate: Hot Ice
Source Institutions
In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

Watercolor
Source Institutions
In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

Optical Morpher
Source Institutions
In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.

In Proportion
Source Institutions
Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

Running on Empty
Source Institutions
In this exercise and nutrition activity, learners will explore how food is the fuel that powers them. They will create a chart to figure out how many calories they burn during recess.

Catapult
Source Institutions
In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

Magnetic Pendulum
Source Institutions
In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.
