Interactive Gumball Machine
Source Institutions
In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
The Dead Zone: A Marine Horror Story
Source Institutions
In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien
Keep Out!
Source Institutions
In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.
Stop: Practice Stopping at Vehicle Intersections
Source Institutions
This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.
Parachuting Pinwheel
Source Institutions
Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.
Kick Stick Challenge
Source Institutions
In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across
Tissue Paper Parachute
Source Institutions
In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.
Can Car
Source Institutions
In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.
Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.
Bearings for Your Whirligig
Source Institutions
Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.
Sky Floater Challenge
Source Institutions
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
Motorized Car
Source Institutions
In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.
Balloon Rocket
Source Institutions
Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
Fruity-Glows: Pictures of Health on a Microarray Canvas
Source Institutions
In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.
Blowin' in the Wind
Source Institutions
In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.
Build a Roller Coaster
Source Institutions
Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.
Puppet Power
Source Institutions
In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.
Grab and Go
Source Institutions
In this engineering activity, learners design and build a mechanical arm to lift a small item.
