Forms of Carbon
Source Institutions
In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.
Shocking Fruit
Source Institutions
In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.

Electromagnetic Dancer: Connect Her Up and Watch Her Dance!
Source Institutions
In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

Circles of Magnetism I
Source Institutions
In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

Tape Electroscope
Source Institutions
In this simple activity, learners create an electroscope by sticking two short pieces of magic tape together and then pulling them apart to find the sign of the charge on an unknown charged object.

Density Intensity
Source Institutions
In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.
Floating Paperclip and Other Surface Tension Experiments
Source Institutions
In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

Neural Network Signals
Source Institutions
In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

Trip Wire
Source Institutions
In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.

Motor Bird
Source Institutions
In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

Earth Attractions
Source Institutions
In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

Exploring the Solar System: Stomp Rockets
Source Institutions
In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

Build a Battery
Source Institutions
Learners build a simple one-cell battery and use an ammeter to measure the flow of current.
Properties of Metals
Source Institutions
In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.

Stretch the Chain and See the Light
Source Institutions
In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

Kosher Dill Current: Make Your Own Battery!
Source Institutions
This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

Another Bright Idea!
Source Institutions
In this activity on page 5 of the PDF, learners use their knowledge of energy and batteries to create homemade flashlights.
