Hidden Alarm
Source Institutions
In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.
That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.
Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
Straws and Pins
Source Institutions
In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.
Pot-in-Pot Refrigeration
Source Institutions
In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
Aviary Architect
Source Institutions
In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.
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.
Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.
Shrinkers: Cook up some plastic!
Source Institutions
In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.
The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
Design and Build a Better Candy Bag
Source Institutions
In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.
Give Me a Brake
Source Institutions
In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.
Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
Marble Run!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.
Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Cactus Needle Phonograph
Source Institutions
Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.
Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.
Vectoring: Steering a Plane
Source Institutions
In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.
