Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.
Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.
Cup Speaker
Source Institutions
Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
You Can't Take It With You
Source Institutions
This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.
Achieving Orbit
Source Institutions
In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat
Bobbing Eyeballs
Source Institutions
In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.
A Dissolving Challenge
Source Institutions
In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.
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.
Rockets Away!
Source Institutions
In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.
Moving Molecules!
Source Institutions
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw
Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.
Catapult
Source Institutions
In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.
Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
Paper Cup Stool
Source Institutions
In this activity, learners will explore how and why weight distribution works.
Go Fly a Kite
Source Institutions
In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.
Mechanical Grabber
Source Institutions
In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.
Chocoberry Chillers: Volume for Thought
Source Institutions
In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.
Puff Mobile
Source Institutions
In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.
