Descartes' Diver
Source Institutions
In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.
Screaming Balloon
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t
Seismic Slinky!
Source Institutions
Did you know that a Slinky makes a handy model of earthquake waves?
Catapult
Source Institutions
In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.
Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
Make a Garbage Bag Kite
Source Institutions
Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Brick Drop Challenge
Source Institutions
In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.
Engineered Sports
Source Institutions
In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.
Parabola Basketball
Source Institutions
In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.
Lava Lamps
Source Institutions
Learners observe working lava lamps to understand how they work (included in PDF link).
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Make a Comeback Can
Source Institutions
Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.
Get-Moving Game
Source Institutions
In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.
Circuit Board
Source Institutions
Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.
Exploring the Nanoworld with LEGO Bricks: Structures at the Nanoscale
Source Institutions
In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.
Tumble Wing Walkalong Glider
Source Institutions
In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Magnetic Marble Run
Source Institutions
Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.
Reusable Rockets
Source Institutions
This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.
