Control the Flow
Source Institutions
In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.
Speedboat
Source Institutions
In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.
Social Fireflies: Pico "Firefly" Communication
Source Institutions
Make two firefly lanterns, then program them to blink to one another and change colors.
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.
Make Your Own Batteries!
Source Institutions
This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.
Laser Lissajous: Binder Clip Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
Hidden Alarm
Source Institutions
In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.
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.
Night Lights
Source Institutions
In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.
Push Pull Painter
Source Institutions
In this activity, learners create painting machines that can paint moving forwards and backwards.
How to Extract DNA From Anything Living
Source Institutions
In this genetics activity, learners discover how to extract DNA from green split peas.
Wind Turbine
Source Institutions
Learners build a wind turbine and test it to see how much energy is created.
Motor Effect
Source Institutions
See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.
Electric Gamebox Challenge
Source Institutions
In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.
Harvesting Chemicals from a Battery
Source Institutions
In this activity, learners take apart a used zinc-carbon dry cell battery.
Mixing and Unmixing in the Kitchen
Source Institutions
In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.
Anti-Gravity Chamber
Source Institutions
In this activity, learners will use magnets and household items to create a structure that allows paperclips to appear like they are floating.
Dough Creatures
Source Institutions
In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.
Shake and Make: Charge Recognition
Source Institutions
In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.
Magnetic Shielding: Magnetic lines stop here
Source Institutions
Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or
