Make Your Own Pendulum
Source Institutions
In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as
Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!
Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
Circuit Bending with Play-Doh
Source Institutions
Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
The Nose Knows
Source Institutions
In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.
Spinning Tops
Source Institutions
Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.
Liquid Layers
Source Institutions
Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.
Depth Perception
Source Institutions
In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Fruit Fly Trap
Source Institutions
Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.
Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
Protect That BRAIN!: Mr. Egghead
Source Institutions
This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.
Magical Match
Source Institutions
In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.
Make a Salt Volcano (Lava Lite)
Source Institutions
This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
Exploring Size: Ball Sorter
Source Institutions
In this activity, learners use sieves with different-sized holes to sort balls by size.
