Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.
Tumble Wing Walkalong Glider
Source Institutions
In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.
Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.
Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Engineer an Aeolipile
Source Institutions
In this engineering design challenge, learners build an air-powered spinning machine.
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.
ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Make a Telescope
Source Institutions
In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.
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.
Exploring the Universe: Space Guess Quest
Source Institutions
Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.
Pressing Pressure
Source Institutions
In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.
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.
Programming Languages: Harold the Robot
Source Institutions
In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their
Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
Playtime Paint
Source Institutions
In this activity on page 9 of the PDF, learners make their own paint using chalk as a pigment and glue and water as binders. This activity introduces learners to special mixtures called suspensions.
Short Circuit
Source Institutions
In this activity about electricity, learners explore what happens when you blow a fuse.
Coding Algorithms
Source Institutions
In this activity, learners will code an algorithm to make it through a maze.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
