Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Investigating and Using Biomass Gases
Source Institutions
In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.
Simulation of Laparoscopic Surgery Lab
Source Institutions
This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.
Floodplain Modeling
In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.
Nano Waterproofing
Source Institutions
This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
Racing with the Sun: Creating a Solar Car
Source Institutions
Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.
Make a Comet Model and Eat It!
Source Institutions
In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.
Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.
Gel Electrophoresis of Dyes
Source Institutions
In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.
Restriction Enzyme Digestion: How does it work? Why is it useful?
Source Institutions
In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
Moving and Working in Space
Source Institutions
In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.
Neato-Magneto Planets
Source Institutions
In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model
