Wire Maze
Source Institutions
Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.
Series and Parallel Circuits
Source Institutions
In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
Conductivity Meter
Source Institutions
In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.
Fork in the Road
Source Institutions
In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.
Magnetism
Source Institutions
In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.
Circuit Sense
Source Institutions
In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Social Fireflies: Pico "Firefly" Communication
Source Institutions
Make two firefly lanterns, then program them to blink to one another and change colors.
Arduino Blink Challenge
Source Institutions
In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.
Penny Battery
Source Institutions
In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.
Electrolysis
Source Institutions
Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
Dance Pad Mania
Source Institutions
Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.
High Tech Fashion
Source Institutions
In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
Using Ohm's Law to Build a Voltage Divider
Source Institutions
In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
Plants: Hanging Tough
Source Institutions
In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge
Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
