Curated OER
Pollution Prevention
Students investigate how to reduce solid and hazardous waste, and estimate the amount of household hazardous waste in their community. Students discuss methods of changing people's habits, and how to convince them to use alternative...

Understanding Filtration
Students discuss the work "Filter." They list types of filters they know about and look at both clean and used filters. Students speculate on how a filter might be important to a fish. They listen to the instructor tell them about...

Electrical Circuits And Switches
Learners design and draw circuits with batteries, small light bulbs and common household conductors. They build and test the circuit then modify it so someone who couldn't use their hands could turn the circuit on and off.

Acid(s)-Base(s) Detective
Students investigate acids, bases, indicators and universal indicators. In this acid and base lesson plan, students test 6 samples with litmus paper and determine if they are acids or bases. They separate out 7 samples using litmus paper...
Curated OER
Investigating the Effect Of Successive Heat and Cool Cycles on a Thermoplastic material.
Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Solution Concentrations
What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original solution.
