Air Cannon
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end
Super Memory
Source Institutions
In this activity (pages 26-29 of the PDF), learners investigate how they can develop super memories by using mnemonic devices.
Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
Plastics the Second Time Around
Source Institutions
In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.
Crime Scene: The Case of the Missing Computer Chip
Source Institutions
Learners use scientific processes to solve a crime. As they get clues, learners must create a hypothesis then adjust that hypothesis as more information is revealed.
How Do Things Fall?
Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Counting Books: Make Your Own!
Source Institutions
On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.
Make an Animation
Source Institutions
In this activity, learners make a device called a phenakistoscope, which displays a continuously looping animation consisting of images drawn onto a spinning disc.
Floating Butterfly
Source Institutions
In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.
Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.
Cake by Conduction
Source Institutions
In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.
It's the "Rain," Man
Source Institutions
In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.
Sliding Gray Step
Source Institutions
How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.
Curious Crystals
Source Institutions
Learners carefully look at four known household crystals.
Zip Line Zoo
Source Institutions
In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.
Tossing Coins
Source Institutions
In this math game (Page 17 of the Are You Game? PDF), learners investigate probability by tossing coins.
Skateboard Disaster
Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.
Number Patterns
Source Institutions
In this lesson, learners are challenged to discover the relationship among six numbers.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
