Who does what? To develop an understanding of the balance of power between the US federal and state governments, class members research responsibilities in terms of legal systems, security issues, economic activities, lawmaking, and...

Let's talk torque! Science scholars evaluate experimental setups during an interactive from the Rotation and Balance series. Individuals calculate the torque of differently arranged weights to determine the effect they have on a balanced...

Scientists use many different kinematic representations of motion. Review each of them with the help of an engaging interactive that is part of a larger series on Newton's laws of motion. The resource provides three levels of challenge...

Get things cooking with the first lesson in this series on the science of food. Working in small groups, young scientists make and record observations about different mystery foods. These descriptions are then shared with the class and...

In this balancing equations worksheet, students use an on line source to answer questions about balanced equations and they write balanced equations for various types of reactions. They balance equations using an on line game that allows...

Young scholars examine the relationships between force, mass and balance through the lens of clay sculpture. They discuss the definitions and concepts behind Newton's Third Law of motion then individually apply these principles to the...

Young scholars determine the mass of various objects. In this integrated math and science lesson, students use an arm balance to compare a known object to a combination of washers with a fixed weight. Young scholars record data,...

Students balance equations using the correct method. In this algebra lesson, students solve linear equations using a virtual balance beam as a manipulative. They play games to reinforce the concept of equations being and staying balanced.

Students play Chembalancer game and balance equations using the trial and error method.

Middle schoolers investigate energy balance equation for five fictitious middle school students by using an energy balance clinic scenario.

In this energy balance worksheet, students track their food eaten over three days, the calories consumed and the calories burned through exercise. Students answer 3 questions about their energy level, calorie balance and the energy...

High schoolers role play as members of a company's import-export purchasing department attempting to develop a positive trade balance with a Pacific Rim nation. They create a company and research a trade nation in order to report to...

In this balancing equations worksheet, students balance ten equations by placing the proper coefficients in front of reactants and products to balance the number of atoms.

In this balancing oxidation-reduction reactions, learners learn how to assign oxidation numbers to atoms in compounds, they learn how to write half reactions in order to balance oxidation-reduction reactions in acidic or neutral...

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students simulate animals in a food chain. In this food chain lesson plan, students are identified as grasshoppers, frogs or hawks. Popcorn is spread across a lawn and students are given baggies (stomachs) and colored sashes to identify...
