Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.
Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
Washing Air
Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.
A Degrading Experience
Source Institutions
In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.
Wind Turbine
Source Institutions
Learners build a wind turbine and test it to see how much energy is created.
Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.
For Your Eyes Only
Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.
Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
How Did That Get There?: Water Pollution
Source Institutions
As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.
Energy Choices Board Game
Source Institutions
This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.
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.
Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.
Building A Storm Drain
Source Institutions
In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
