Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).
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.
Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
Recycling Rules: Understanding Recycling and a MRF
Source Institutions
In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
Otter Smorgasbord
Source Institutions
In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.
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.
Trail Construction
Source Institutions
In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
Off Base
Source Institutions
In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
Round, Light and Hollow
Source Institutions
In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.
Heart Rate and Exercise
Source Institutions
In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with
The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.
Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
Where Do We Choose to Live and Why?
Source Institutions
In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.
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.
Rubber Band Boat
Source Institutions
In this activity, learners build styrofoam boats powered by twisted rubber bands.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
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
The Dead Zone: A Marine Horror Story
Source Institutions
In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien
