Can Car
Source Institutions
In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.
Change in Temperature: Exothermic Reaction
Source Institutions
Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.
Slime
Source Institutions
Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.
Sky Floater Challenge
Source Institutions
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
Build a Roller Coaster
Source Institutions
Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.
Dinosaur Bone Experiments
Source Institutions
This activity features two connected hands-on activities about dinosaur bones.
Prepare for a Construction Zone Field Trip
Source Institutions
In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.
Pop Fly
Source Institutions
In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
Production of a Gas: Controlling a Chemical Reaction
Source Institutions
Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.
Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
Outbreak!: Investigating Epidemics
Source Institutions
A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.
Making Circuits
Source Institutions
In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
