A LOT OF THIS FOR A LITTLE OF THAT
Students describe the import and export of agricultural products and gain a comprehension of the concept of supply and demand. They discuss exports and imports. Students have small world maps on each desk, they identify the countries...

Surpluses, Shortages, and Equilibrium
High schoolers review and discuss the meaning of equilibrium. As a class, they participate in a game of "The Price is Right" in which they guess the true market price of various items. They explain how shortages and surpluses tend to...
Curated OER
Establishing Hardy-Weinberg Equilibrium
Students study how Hardy-Weinberg Equilibrium was established and what assumptions and conditions are necessary to reach Equilibrium. They record class data on their charts. Frequencies are calculated.

Observing the Effect of a Change in Conditions on a System at Equilibrium by Applying Le Chatelier's Principle
Students describe the Le Chatelier Principle. They participate in an experiment in which they observe the changes in an equilibrium system. They answer discussion questions to end the lesson.

How Can We Calculate an Equilibrium Constant?
High schoolers explain how equilibrium quantities are changed by temperature, pressure or different concentration of substances. They work together to complete equilibrium equations. They identify the relationship between absorption of...
Curated OER
Tightrope Trials
Students research the concepts of center of mass and how to make different things balance. They make symmetrical cut-outs of different "creatures" and experiment with how they balance on a tightrope of string.

Chemistry Practice
In this chemistry practice worksheet, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.
Curated OER
Computer Science: Temperature
Students conduct an experiment on heat transfer and how it works. They record the temperature in whatever environment is surrounding the container and run experiments that use at least two different ambient temperatures. Students...
Curated OER
Balanced Forces
Young scholars are able to explain why football running backs benefit from having a lower center of gravity when opponents are trying to tackle them. They explain why racing cars are designed to have a low center of gravity. Students...
Curated OER
Perching Parrot
Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. They also analyze why all forces on an object must cancel out exactly for an object to be stationary.

Main Sequence Stars: A System in Equilibrium?
Fourth graders study the equilibrium of internal forces in a main sequence star.
