Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
Creepy Crawlers
Source Institutions
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.
Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.
Up and Down Donkey
Source Institutions
In this game, learners build up six stacks of cards in the middle of the table, face up, in order from 1 at the bottom to 20 on the top. The first player to get rid of all his cards is the winner.
Name-a-Saurus
Source Institutions
In this paleontology activity, learners explore the system behind dinosaur nomenclature.
In the Middle
Source Institutions
In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.
Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
Underwater Fireworks
Source Institutions
In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Now or Later: The "Recency/Primary" Effect
Source Institutions
In this activity (18th on the page), learners conduct an experiment to examine memory.
How Far?
To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
Grabbing a Bite to Eat
Source Institutions
In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.
Glowing in the Dark
Source Institutions
In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.
Color Draw
Source Institutions
In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.
A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.
Bronx Cheer Bulb
Source Institutions
In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu
Paper Animals
Source Institutions
This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.
Perching Parrot
Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.
