Where the Rubber Meets the Road
Eighth graders examine two different types of tires and the effects of different factors on the amount of force needed to overcome sliding friction such as when the vehicle tries to stop.
Curated OER
Force/Newton's Laws/Friction
Learners describe how to recognize a force, define balanced and net forces, state Newton's first law of motion, explain why friction works, state Newton's second Law of Motion, and explain why the direction of force is important.

Tightrope Trials
Learners 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.
Curated OER
Seesaws
Students make direct comparisons between objects using balance and spring scales. They also are encouraged to estimate which object is heavier by holding the objects before using the balance scales. Comparing the masses of objects is the...

Planets in Balance
Students study the solar system by researching the planets. In this exploratory lesson students divide into teams and create mobiles.
Curated OER
Torque Me Off
Students investigate the lever and the mathematics associated with levers. They determine the conditions necessary to balance a system of forces around a fulcrum.
Curated OER
World Geography: Climate Change Round Table
Students are able to explain the suspected causes of relatively recent climate changes, specifically the observed global warming. They discuss how unusual or extreme global warming disrupts the balance of the earth's geo-spheres.

What is the Rock Cycle and Its Processes?
Geology beginners examine three different rock samples and determine their origin by their characteristics. By making and recording observations, they become familiar with features of igneous, metamorphic, and sedimentary rock types....
Curated OER
To Dam or Not to Dam
Young ecologists explore the Aswan Dam in Egypt via the internet. Each collaborative group is assigned a specific article about the ecological impact of the dam. Then they prepare a presentation to share with the rest of the class. Some...
