Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Shape Up!
Source Institutions
In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.
Solar Cell Simulation
Source Institutions
In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.
Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.
Make a Wire Critter That Can Walk on Water
Source Institutions
In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.
Stroboscope
Source Institutions
In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.
Sliding and Stuttering
Source Institutions
Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.
Radar Mapping: What's in the Box?
Source Institutions
In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.
Rover Races
Source Institutions
In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through
Density Intensity
Source Institutions
In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.
The Nose Knows!
Source Institutions
In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.
Balsa Towers
Source Institutions
Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.
Taking Its Temperature
Source Institutions
In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Star Power
Source Institutions
In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.
What's the Matter
Source Institutions
In this activity, learners identify different classes of matter based on physical properties.
Exploring the Nanoworld with LEGO Bricks: Structures and Their Construction at the Nanoscale
Source Institutions
In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.
