Tenth graders organize and interpret data from a student health program.  In this physical education instructional activity, 10th graders use a body composition analyzer over 8 weeks to determine the validity of a...

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

In groups, students create their own scientific impact experiments using ordinary materials, and observe and measure results with a variety of impacting bodies and velocities.

Learners become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.

Students relate meteorites to the mantle and crust of asteroids.  In this planetary instructional activity students complete experiments to model the separation of light.

Students observe how to distinguish observations form inferences.  In this examining inferences instructional activity students list observations relating to the activity and discuss the importance of them. 

Students explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...
