DNA Extraction from Cheek Cells
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
Design a Grabbing Tool
Source Institutions
Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.
Speedboat
Source Institutions
In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.
DIY Sunprints
Source Institutions
In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.
Social Fireflies: Pico "Firefly" Communication
Source Institutions
Make two firefly lanterns, then program them to blink to one another and change colors.
Create Your Own Decoupage
Source Institutions
In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.
Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.
Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
Production of Oxygen
Source Institutions
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.
Shrinkers
Source Institutions
In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.
Concentrate!
Source Institutions
In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.
Laser Lissajous: Binder Clip Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
Earthquake Science: Soil Liquefaction
Source Institutions
This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.
Make a UV Detector
Source Institutions
In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.
"Baseketball": A Physicist Party Trick
Source Institutions
This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.
Yeast-Air Balloons
Source Institutions
In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.
Telescope Treasure Hunt
Source Institutions
This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.
Scratch Film
Source Institutions
In this activity, learners manipulate film to create homemade movies. Scratch Film, also known as Direct Animation, is the process of drawing and scratching designs directly onto film.
Spot the Sunspots
Source Institutions
In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.
Small Habitats
Source Institutions
In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).
