Program a Friend
Source Institutions
In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.
Convection Demonstration
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.
A Universe of Galaxies: How is the Universe Structured?
Source Institutions
This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.
Who Dirtied The Water?
Source Institutions
In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).
Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
Exploration Tank
Source Institutions
This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.
What is Energy?
Source Institutions
In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.
Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
Three Colors of Light
Source Institutions
Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.
Pipes of Pan
Source Institutions
Create an instrument that you don't play--you just listen to it through tubes of various lengths.
Build A Dome
Source Institutions
In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.
Pollinator Play
Source Institutions
In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.
Magnetic Lines of Force
Source Institutions
With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.
T-Shirt Transformation
Source Institutions
In this activity, learners will repurpose an old t-shirt to create their own yarn or string.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
Afterimage
Source Institutions
In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an
Acting Out
Source Institutions
This activity (on pages 21-32 of PDF) has learners act out several classic brain teasers.
Cactus Wheel
Source Institutions
In this outdoor activity/field trip, learners explore the concept of population density.
Make Your Own Ant Farm
Source Institutions
In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.
