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.
Digestion
Source Institutions
In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.
Crossing the Synaptic Gap
Source Institutions
In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.
Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.
Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
Rocket Launchers
Source Institutions
In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.
Public Key Encryption: Kid Krypto
Source Institutions
In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.
Stories in the Sky
Source Institutions
In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.
Battleships: Searching Algorithms
Source Institutions
This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Soccer
Source Institutions
In this math activity (Page 12 of the Play Ball! PDF), learners play a game of "soccer" and analyze the results of the game.
Marble Game
Source Institutions
In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.
A Place in Space
Source Institutions
Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.
Atoms and Matter (3-6)
Source Institutions
In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.
Defining Density
Source Institutions
In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.
Twenty Guesses: Information Theory
Source Institutions
This activity introduces the idea that computer scientists measure information by how "surprising" a message is.
Heavyweight Champion: Jupiter
Source Institutions
In this activity, learners confront their perceptions of gravity in the solar system.
Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
Basketball
Source Institutions
In this math activity (Page 14 of the Play Ball! PDF), learners play a game of "basketball" and analyze the results of the game.
