Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Launch It
Add to list DetailsIn this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.
Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Mega Bounce
Source Institutions
In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.
Super Bounce
Source Institutions
In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
Circuit Board
Source Institutions
Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.
Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
Bubble Trouble
Source Institutions
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.
Exploring How Robots Move
Source Institutions
In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
