Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
The Poor Cartographer: Graph Coloring
Source Institutions
In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.
My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
Blow-and-Go Parachute
Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Programming Languages: Marching Orders
Source Institutions
In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.
Rocket Science
Source Institutions
Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.
Manufacturing Technologies: Making a Picture Frame
Source Institutions
Learners examine the manufacturing process while they make picture frames from cereal boxes.
Exploring the Solar System: Mission to Space Board Game
Source Institutions
In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.
Exploring the Solar System: Stomp Rockets
Source Institutions
In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can
Rocket Pinwheel
Source Institutions
This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.
Supporting Structures
Source Institutions
In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.
Rippin' Rockets
Source Institutions
In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.
Weighty Questions
Source Institutions
In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.
A Merry-Go-Round for Dirty Air
Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.
Glider
Source Institutions
In this activity, learners construct a paper glider to experiment with aerodynamic forces.
