A-Mazing Robot
Source Institutions
This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.
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.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Twisted Tesselations
Source Institutions
In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Tinkering with Tops
Source Institutions
In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Clap Sensor: Build a Sound Sensor Using a Pico Cricket
Source Institutions
This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.
Non-Round Rollers
Source Institutions
Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Our Sense of Touch: Two-Point Discrimination
Source Institutions
In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.
Our Sense of Sight: Eye Anatomy and Function
Source Institutions
In this activity, learners investigate the sense of sight and develop and conduct their own experiments.
Stranded
Source Institutions
What's a more compelling problem to solve than being stranded on a deserted island?
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Getting There!: Navigation and Trajectory
Source Institutions
In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.
Ships Ahoy!
Source Institutions
Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.
Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.
Introduction to Ocean Zones
Source Institutions
In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.
Water Fountain
Source Institutions
In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.
Tennis Anyone?
Source Institutions
In this activity, learners explore sports engineering and advanced materials development.
