Ziploc Digestion Simulator
Source Institutions
In this biology activity, learners recreate the process of digestion in a zip lock bag. A bit of soda pop added to some crumbled crackers approximates how acids in the stomach dissolve food.
Curve Control
Source Institutions
In this online game, learners must keep their snowboarding racer in the middle of the course without veering off track or hitting obstacles.
Mix & Match Estimation
Source Institutions
In this activity, learners use their estimation skills to match the unmarked containers to their amounts.
Bat Echolocation
Source Institutions
In this activity, learners investigate how bats use echolocation to navigate. One learner is assigned to be a bat, while the other learners are selected to be either moths or trees.
Frosty Glasses
Source Institutions
In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.
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
Vibrating Pennies
Source Institutions
Conduct a simple experiment to explore how temperature changes can make things expand or contract.
Alien Encounter
Source Institutions
Use multiplication to help the aliens find out how much fuel they need to get their spacecrafts home.
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.
Static Electricity
Source Institutions
In this activity, learners will explore ways static electricity interacts with the surroundings of an object. The activity has step-by-step instructions in English and Navajo.
Extra Bounce
Source Institutions
In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.
What am I?
Source Institutions
In this activity, learners examine nanoscale structures of common things.
Shrinking Coin
Source Institutions
In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.
Water Engineering
Source Institutions
In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.
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?
Balloon Nanotubes Tabletop
Source Institutions
This activity introduces learners to the structure and properties of carbon nanotubes.
Helicopters
Source Institutions
In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.
Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.
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.
