Three Bean Salads
Source Institutions
This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.
Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
Sharks: Taking a Bite Out of The Myth
Source Institutions
In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.
Production of Carbon Dioxide
Source Institutions
In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.
Changing Shadows
Source Institutions
In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.
Fantastic Plastic
Source Institutions
In this activity, learners investigate the properties of plastic bags. Learners find out what happens when they slowly push a pencil through a plastic bag filled with water.
Take Ten: Cleaning Up is Fun
Source Institutions
In this activity, learners will make cleaning up more fun with predictions and counting. Estimate how many things are on the floor (or table), then count as they are picked up.
Population Study Game: Oh, Deer!
Source Institutions
In this activity, learners model a population of deer and see how the number of deer changes over time.
Balloon Surprise
Source Institutions
In this activity, learners discover a trick to release the air out of a balloon without popping it.
Slowing the Flow
Source Institutions
In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.
Frog Eggs
Source Institutions
In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.
Bernoulli's Blowout
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
Handwriting Analysis
Source Institutions
In this forensics activity, students will explore the methods that investigators use to confirm the authenticity of handwriting.
Extra Bounce
Source Institutions
In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.
Shrinking Coin
Source Institutions
In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.
Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
Capturing Carbon Dioxide
Source Institutions
In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.
Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.
