Pupils individually determine what they need to know about osteoporosis and how they will find that information. They share their thoughts with a partner before moving on to share with the class. The class arrives at a list of a set of...

Introduce your class to the steps that occur in the manufacturing of parts, the assembly, and the testing of a Mars rover. Pupils learn about fabrication techniques and tolerances in the manufacturing process. 

You've got to pump it up! Using the equations for projectile motion and Bernoulli's Principle, class members calculate the water pressure in a water gun. The pupils collect data on the number of pumps and distance traveled in order...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

  Students consider the life span of dams, and what would happen if a dam falls apart.  In this environmental impact lesson plan, students discuss what the purposes of dams are, how they could be damaged.     

A series on environmental engineering introduces the class to issues that environmental engineers work to solve. This first lesson focuses on air and land issues, and looks at ways to reduce pollution.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Students analyze information and draw conclusions about the reality of human life expectancy; the battle between health care technology and our own internal time clocks. Students answer questions such as "Why does aging occur and can...

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...
