Read any financial website or book, and it is bound to discuss the words asset and liability. But what do these words actually mean to the class? The resource effectively explains by using multiple formats and techniques, including...

Break out the balances for this primary grade lesson on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom objects. A graphic...

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...

What's the difference between civil and criminal law? How do the court proceedings differ in these two types of trials? How do the standards of proof differ? Why do these differences exist? As part of their examination of the...

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...

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...

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...

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. 

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...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

High schoolers review half-reactions and practice balancing redox equations in order to help them solve problems in chemistry.

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Should the United States Supreme Court have the power of judicial review? Instructors guide class members through a review of Marbury v. Madison and assist class members in writing a brief of the case. As independent practice,...

Middle schoolers simulate online the formation of Ape Cave, in order to better explain its construction. They observe, illustrate and discuss geological features of this lava tube.

Students evaluate how the United States government has maintained a balance between protecting rights and maintaining order. They analyze the impact of Supreme Court decisions on governmental powers and the rights and responsibilities of...

High schoolers explore volcanoes, locate them on maps, record general information about volcanoes, and organize information on a fact sheet.

Students create a mock new business for which they design a PowerPoint presentation. They include company information, financial statements, graphs, advertising and management promotion pages in the final presentation.

Sixth graders simulate the creation of impact craters on Mars.Through the creation of model surfaces, the effects of an impacting object's mass, velocity and size are determined, and the features of the resulting crater are identified.

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Fourth graders study about sound waves and how they behave in various media. They create a soundproofed container. They explain that velocity describes a change in distance over time.

Students receive a basis for understanding the three main classifications of rock: igneous, sedimentary and metamorphic. They engage in a hands-on activity designed to give them an appreciation for rocks and minerals.

Tenth graders create and maintain a ledger, write an essay for the process, and learn to keep financial accounts through the ledger. In this ledger instructional activity, 10th graders define an accounting ledger and create one for the...

Middle schoolers develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

High schoolers identify the process of writing a case brief. They analyze the case McCulloch v Maryland. After a lecture/demo, students utilize a case study worksheet imbedded in this plan to help them explain the process of performing a...
