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.
Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.
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.
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
Helicopter Twirl
Source Institutions
Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.
Nosedive
Source Institutions
This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.
Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.
Echo Base Bobsleds
Source Institutions
The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.
Round & Round
Source Institutions
In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
