Students are introduced to the concept of free enterprise. In groups, they discuss the price of various food items and decide on which item to produce. They calculate the cost of producing the item and share their results with the class.

Students explore the simple machine of a wedge. In this wedge lesson, students test wedges on different materials including wax, soap, clay and foam. They learn how a wedge was used to build the ancient pyramid and modern day skyscrapers.

Middle schoolers examine where energy comes from and how it can be used.  In this solar energy lesson students explore different aspects of the sun. 

Students examine force and conduct activities that model parachutes and helicopters.  In this airplanes lesson students identify the forces that make airplanes fly higher and land. 

Students study the human digestion system and the functions of the stomach and small intestines.  In this digestion lesson students view a demonstration on the process. 

Students study what passive solar design is for buildings and structures.  In this solar design lesson students identify passive solar design techniques.

Students examine the properties of light and the behavior of light during interference.  In this electromagnetics lesson students explain behaviors of light.

Young scholars study asteroids and how their size relates to a possible danger of one colliding with Earth.  In this asteroids lesson students see how big an asteroid has to be to cause destruction to Earth. 

Students develop a painless means for identifying cancerous tumors.  In this imaging lesson students list the information that may be needed to answer the problem.

Students explain what biodiversity is and how adaptive features are maintained in a population.  In this biodiversity lesson students complete a simple activity involving mouse populations.

Students explain how laser security systems work.  In this security system design lesson students create a presentation of their system that they designed. 

Students complete experiments to determine how rocket fuel is affected by surface area and temperature. They compare the reaction rates of antacid tablets. They discuss their results to complete the lesson.

Learners collect and analyze data. In this statistics lesson, students display their data using excel. They plot the data on a coordinate plane and draw conclusion from their data.

Amazing science can sometimes happen right before your eyes! The class gets cozy as they watch crystals grow. They use Epsom salts, rocks, and food coloring to create crystals. They'll observe the entire process, documenting every step...

Examine paper money from the American revolution! Historians study the paper bills and discuss the history of money. How has money changed over the times? Activities are included. 

Students examine the result of a negative charge. After rubbing a balloon with a wool cloth, students hold it over a mixture of salt and pepper. They observe the pepper "jumps" to the balloon. Students discuss their observations and then...

Learners calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Learners explore wind energy by making a pinwheel to model a wind turbine. They experiment with their turbine by placing it in different locations for optimal energy.

Students build simple gear trains and record data to discover how to compute gear ratios. They investigate the definition of torque and how torque can be increased or decreased in a gear train.

Learners examine how infrared works with everyday items. In this investigative lesson, students examine how we use infrared in household items. They will conduct an experiment to create an infrared remote that works around corners as...

Students conduct a simple inertia demonstration by spinning a hardboiled and raw egg. They push a wagon to demonstrate inertia. They explore Newton's first and second laws of motion.

Young scholars study different ways of using solar energy. They design a solar water heater and determine how much water it can heat in a set amount of time. They examine how the heaters work by solar radiation and convection.

Students discuss the different types of tornadoes and how they form. Working in groups, they record journal entries by conducting experiments with water bottles simulating vortex formation.

Students examine how a pollutant recovery method functions in cleaning industrial air pollution. They listen to a teacher-led discussion, conduct an experiment with balloons, static electricity, and pepper, and observe and record the...
