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.
Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
Draft Detectives
Source Institutions
In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.
Squeeze the Stream
Source Institutions
In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.
Feather Rockets
Source Institutions
In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.
Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.
No Pressure
Source Institutions
In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.
Mid-Air Maneuver: Skateboard Science
Source Institutions
To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.
Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
¡Paracaídas!
Source Institutions
En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.
Decibel Cannon
Source Institutions
In this activity, learners will construct an air cannon as a model for the human ear.
Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.
Twist and Spout
Source Institutions
In this activity, learners make their own "tornado" using two soda bottles and water.
Frosty Glasses
Source Institutions
In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.
Weight For It!
Source Institutions
In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.
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.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
