Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Pop Rockets
Source Institutions
In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.
Onion DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.
Space Stations: Measure Up!
Source Institutions
In this activity, learners work in pairs to measure each other's ankles with lengths of string.
The Colors of Flowers
Source Institutions
In this activity, learners perform an experiment to find out what determines a flower's color.
Head in the Clouds
Source Institutions
In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.
Tug-of-War
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.
What's in Your Blood?
Source Institutions
Doctors often send a sample of blood to a lab, to make sure their patients are healthy.
pHun with Cabbage
Source Institutions
In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.
Earthquake Energy
Source Institutions
In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.
Copter Engineering
Source Institutions
In this activity, learners engineer a paper helicopter that spins to the ground when dropped.
Zipline
Source Institutions
In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.
Resonant Rings
Source Institutions
Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.
Suminagashi: Floating Ink Paper Marbling
Source Institutions
In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.
Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
How Small Can You Cut?
Source Institutions
In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.
Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl
Drip Drop
Source Institutions
In this water activity, learners explore how water drops behave on different surfaces.
Doppler Effect
Source Institutions
Sound changes pitch relative to how you or the source of the sound is moving. Use this simple activity developed by the Exploratorium to experience the Doppler Effect yourself!
