Fun With Adhesives
Students observe, measure, and record the properties in making objects stick together using science tools. In this science lesson plan, students explore with their senses while mixing flour and water. Additionally, students share their...
Curated OER
Math for the Frontier
Make history come to life by using the Frontier House series to engage students in the past. Your class will "prepare" for a trip to 1833 Montana. They will learn about homesteading, frontier life, inflation, and cost of living. Using...

A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...
American Chemical Society
Using Chemical Change to Identify an Unknown
If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...
American Chemical Society
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...
American Chemical Society
Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...
American Chemical Society
Protons, Neutrons, and Electrons
Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....
American Chemical Society
Changing State: Evaporation
Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...
American Chemical Society
Heat, Temperature, and Conduction
How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer.
American Chemical Society
What is Density?
Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...
American Chemical Society
Density of Water
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.
American Chemical Society
Density: Sink and Float for Solids
Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...
