Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final instructional activity in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter...

Oceanographers participate in a memorable hands on experience about buoyancy. They build a model of a submersible using a plastic bottle and a balloon. Afterward, they answer assessment questions. An answer key and some terrific...

If a ski lift had rockets, imagine how fast it would be! Scholars let their imaginations take flight as they build models for such a ski lift. Rather than using a rocket, though, they'll use a much safer balloon as the power source.

Package design is a mathematical task for any business. Young scholars use a package design to determine the number of packages required for specific shipments. Using ratios, proportions, and fractions, they make decisions about the best...

Students conduct an experiment about air volume, density, and pressure. In this air lesson, students discuss air, and how it moves. They make predictions about what will happen during the balloon and string experiment. They document the...

In this recognizing different types of changes worksheet, students answer questions about such things as reversible change, irreversible process, climatic change, filtration process, physical change, and change in the state of a...

Students investigate surface tension in water. In this water molecules and surface tension lesson, students observe 3 demonstrations to show how water molecules are attracted to one another, how soap reduces the surface tension in water...

In this conservation of mass worksheet, middle schoolers experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the...

Students build a model of a submersible that will allow them to explore ballasts and how they operate.  For this hands on lesson students participate in an activity that shows them how to control buoyancy.

Students create a model of the lungs and diaphragm. In this breathing lesson, students create a model out of a plastic bottle and balloons. They see how the diaphragm helps to fill the lungs with air. 

Fourth graders study the sombolism between Populism of the 1890's and the story of The Wizard of Oz.

Students participate in a creative project where they construct globes. They label specific places on the globe that helps them learn how to read an actual globe.

In this mass worksheet, students fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.

In this economic systems worksheet, students read and follow the provided 5 tips to locate, analyze, and discuss macroeconomics current event issues. 

Fourth graders read the story Alexander, Who Used to Be Rich Last Sunday and discuss money issues. In this money lesson plan, 4th graders create a budget.

Students complete an experiment in which they discover air has weight. They use the same size balloons to explain this concept. They also examine thunderstorm safety.

Students determine if carbon dioxide has mass. In groups, they use a standard set of materials to test the carbon dioxide. They answer questions on their lab sheet and discuss them as a class.

Pupils consider the relationship between pressure and temperature. They observe a demonstration and explore the relationship between heat and volume when pressure remains constant. Students discuss relational causality and consider how...

A description of inflation, deflation, the consumer price index, and the implicit price deflator.

In this lesson summary review and remind yourself of the key terms and calculations used in measuring inflation. Topics include the consumer price index (CPI), calculating the rate of inflation, the distinction between inflation,...

How does inflation affect a country's well-being? What are some examples of high and low inflation?.

Explore the inflation rate from 2013 through this informative case study. Trace the consumer trends through the graphs and charts on the site.

This site from the St. Joseph's College provides an explanation of inflation, including a section on how to calculate a consumer price index.

This investigation begins with a discussion of spare change. Students are asked to compare and analyze peoples' attitudes toward coins today to those of the past. Students then complete an activity that teaches them how to compare...
