Plastic Wrap
Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...

Building Better Buses: Transportation Design Challenges
Scholars learn about a series of three challenges when they design a bus system for a small town. They determine the bus routes and then figure out the best type of fuel to use before considering the cost of going electric. Learners...

Hydrophobic Surfaces—Deposition and Analysis
Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Insulation Materials Investigation
Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Shedding a "Little" Light on Cancer Surgery
Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...
Carnegie Mellon University
Transportation
Teach your environmental studies, life science, or engineering class how an internal combustion engine works using the first few slides of the accompanying presentation. Then, focus in on the resulting carbon emissions. Finally, take a...
Curated OER
Ecology of the Dump
Students determine which types of garbage are biodegradable and which are nonbiodegradable. They practice measuring skills, hypothesizing, taking data, and writing a lab report. Students observe the relative biodegradability of metal,...

Bubble Gum Chemistry
Students explore the concept of graphing data. In this graphing data lesson, students determine the percentage of sugar in bubble gum. Students graph type of gum vs. sugar percentage. Students create a table of their data.
Curated OER
Ecology of the Dump
Young scholars recreate landfills in petri dishes, observe relative biodegradability in a year-long project, and isolate a cellulose degrading bacteria while discovering the need for recycling and the serious problem waste management has...
