Much like the methods of group work, the writers of the Federalist Papers worked together to advocate for their viewpoints against the anti-federalists. The resource enables learners to break into small groups and conduct research before...

You'll C-E-R a difference in classroom achievement after using a helpful lesson. Designed for economics, civics, government, and US history classes, participants practice using the CER model to craft arguments about primary and secondary...

Remind young historians that many technological advancements influenced the events of World War I. After analyzing technology's evolution through primary sources, discussing the changes over time, and watching various video clips,...

Is propaganda from World War I any different than the propaganda of today? Class members learn about the effectiveness of advertising and its influence on American's behavior. Activities include a propaganda think sheet, assessments of...

Capitalism, socialism, communism ... these may seem like a whole bunch of isms to your scholars. High schoolers won't  confuse them after completing an informative resource. Your class masters how to use primary sources to critically...

According to the United Nations, climate change affects every country on the planet. This research project encourages scholars to explore the factors that affect climate change from different perspectives: climate scientist, policy...

Are our oceans really suffering due to the choices humans make? The sixth and final installment in the volume of activities challenges research groups to tackle one of six major topics that impact ocean health. After getting to the...

Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

All synthetic materials began as natural materials. An engaging lesson begins with a hands-on activity and an example of the type of research that scholars perform independently. Then pupils receive a topic and begin researching the...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach the proper...

Can your breath change the acidity in a liquid? A lesson begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

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...

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...

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class members experiment to...

Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

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...

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 two...

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.
