Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Pickle-oh!: Musical Pickle Instrument
Source Institutions
What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.
Clap Sensor: Build a Sound Sensor Using a Pico Cricket
Source Institutions
This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.
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.
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.
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.
Wind Turbine
Source Institutions
Learners build a wind turbine and test it to see how much energy is created.
Harvesting Chemicals from a Battery
Source Institutions
In this activity, learners take apart a used zinc-carbon dry cell battery.
Personal Fan
Source Institutions
Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.
Got Gas?
Source Institutions
Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.
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.
Circuit Bending with Play-Doh
Source Institutions
Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!
Overnight Painting Machine: Pico Cricket Activity
Source Institutions
This activity requires a Pico Cricket (tiny computer).
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.
Wandering Wands
Source Institutions
In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.
Musical Ice: How to Make an Ice Theremin
Source Institutions
Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.
Piezoelectric One-Way Remote
Source Institutions
In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.
Motor Learning
Source Institutions
In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.
