Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.
Lateral Inhibition
Source Institutions
Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.
Wolf Survival is Just a Roll Away
Source Institutions
In this simulation activity, learners will raise a pack of wolves under ten different conditions: without human interference and with human interference.
Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of
Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.
Musical Coat Hangers
Source Institutions
Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!
By the Numbers
Source Institutions
Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.
Mirror Messages
Source Institutions
In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.
Solving Playground Network Problems
Source Institutions
In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.
Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.
Mystery Jars: Estimate Contents
Source Institutions
This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.
Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
Passion for Pixels
Source Institutions
In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.
Egg Bungee
Source Institutions
Learners attach an egg to a rubber-band bungee cord and drop the egg.
Mighty Molecules
Source Institutions
In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.
Chemical Reactions in Your Mouth
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.
Oscillating Woodpecker
Source Institutions
In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.
Train Your Brain
Source Institutions
In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.
Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
Dance Diagram
Source Institutions
Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.
