Looking Through the Algebraic Lens
Source Institutions
In this two-part math lesson, learners investigate problems that foster algebraic thinking across content strands. In the first part, learners explore even and odd numbers linked to quilts.
Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
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.
AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Super Soaking Materials
Source Institutions
In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Hydraulic Car
Source Institutions
In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.
Propeller-Powered Car
Source Institutions
In this activity, learners construct cars that are powered by hand-made, electric propellers.
Cardboard Opaque Projector
Source Institutions
In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
Maritime Munchies
Source Institutions
In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.
Wire Maze
Source Institutions
Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.
Cardboard Box Camera Obscura
Source Institutions
In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.
The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.
Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.
Water Tower Challenge
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.
Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
Hand Biometrics Technology
Source Institutions
In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin
Tissue Paper Parachute
Source Institutions
In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.
Conveyor Engineering
Source Institutions
In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
