Touch and Go
Source Institutions
As learners play this game, they develop logic, geometry, and spatial visualization skills. Players start out with an empty hexagonal grid.
Drawing From Nature
Source Institutions
In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.
Magic Sand: Nanosurfaces
Source Institutions
This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).
Crystal Stencil Stars
Source Institutions
In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.
When is a Glass of Water Really Full?
Source Institutions
In this activity, learners see how many coins they can add to a full glass of water before the water overflows.
Homemade Rube Goldberg Machine
Source Institutions
In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.
Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.
T. rex Cretaceous Treat
Source Institutions
In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.
Make a Mobile!
Source Institutions
In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.
Scale Model of Sun and Earth
Source Institutions
In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.
Geometry and Spatial Relations: It's a Perfect Fit
Source Institutions
In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.
Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.
Hungry as a Caterpillar
Source Institutions
In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.
The Great Toss Off!
Source Institutions
In this math game, learners toss plastic cups to land just right and collect points to win.
Gravity and Muscles
Source Institutions
In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.
Anti-Gravity Cups
Source Institutions
In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.
Make A Map for A Treasure Hunt
Source Institutions
In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.
Aluminum Boats
Source Institutions
Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?
Mechanical Madness
Source Institutions
In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.
Head Harp
Source Institutions
Put a string around your head, and play it! Learn about vibration, sounds, and pitch.
