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.
Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
Snake
Source Institutions
In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.
Newspaper Bridges
Source Institutions
In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
The Senses of "Unknown Creatures"
Source Institutions
In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.
Turning the Air Upside Down: Spinning Snakes
Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
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!
Cabbage Chemistry
Source Institutions
In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
Keep it Cool
Source Institutions
In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
Waterproof that Roof!
Source Institutions
In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
No-Slip Grip
Source Institutions
In this physical sciences activity, learners explore friction. Learners investigate the factors that affect the force required to move an object.
Cohesion Coin
Source Institutions
In this activity about the property of water (page 6 of the PDF), learners use a coin to demonstrate cohesion between water molecules, exploring the molecular forces that allow water molecules to "
