Students study the law of sine and cosine. In this pre-calculus lesson, students create a triangle and identify the different ratios of a non-right triangle. They use the properties of sine and cosine to solve.

If you have solar car kits for your junior high schoolers, they can experiment with photovoltaic cell angle, light intensity, and aerodynamic design to discover what makes their car move more quickly. This is a classic activity to use...

Progress through various aspects of the  "The Beautiful Era" in this presentation. Political, technological, and scientific contexts surround the time of innovation and change in the world landscape. The short length of this slide...

Define six common forces: propulsion, air resistance, water resistance, friction, gravity, and upthrust. A picture of a Smart Car is displayed with arrows showing all of the forces acting on it when it is motion. A picture of a rubber...

Discuss with your oceanographers what forces cause nearshore upwelling and downwelling. Display a line of wind vectors alongside a graph of the temperatures so that they can discover whether or not they are related. Discussion questions...

Students explore the challenges astronauts face while eating in outer space. In small groups, they design and construct an original model device to assist astronauts eat in a microgravity environment.

Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...

Students observe a demonstration presented by the teacher covering different types of energy. They participate in an experiment where they study numerous physics vocabulary words and visit websites that demonstrate examples of these...

In this interactive grammar worksheet, students select the word from each drop down menu that completes each of the eight sentences. This worksheet focuses on using the present perfect progressive or nonprogressive tense.

Middle schoolers use cereal boxes, paint, buttons and glue to design and make a frame for a photograph. They consider the different processes involved in making the frame and discuss how their observations apply to manufacturing systems...

Students design and create their own heart valves out of a variety of materials. Their heart valves are one way valves designed for water flowing through a tube representing blood moving through the heart.

Middle schoolers work in groups to conduct experiments the demonstrate the differences between static and kinetic friction. They consider how friction affects us in our everyday lives, determine the effects of weight on friction and...

Students investigate the three types of material stress related to rocks. They identify the three types of stress, conduct a simulation by breaking bars of soap using only their hands, and complete a worksheet.

Students study concepts of energy and energy transfer. They look at how these concepts apply to musical instruments. They study the law of conservation of energy. They use the concepts studied in the lesson to design a musical instrument.

Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. They build a conductivity tester to determine whether different objects are...

Learners examine the current technologies used in mapping resources in the marine environment. They look at remote sensing, sounding, and underwater vehicles. They examine image from the benthic habitat produced by the GIS in order to...

Students investigate types and sources of indoor air pollutions both at home and in school. They decide on how to prevent poor indoor air quality. They debate smoking in order to determine how language usage can be an influence in...

Students study the parts of the human respiratory system while examining the gas exchange that takes place in the lungs. They make a model lung. They look at how the respiratory system is affected by spaceflight.

Young scholars investigate the friction between tires and the road and how it affects the movement of cars while driving. They discuss and define friction, experiment with sandpaper and wax paper to determine which material provides the...

Students simulate different spacecraft missions using materials provided. In this space science lesson, students observe and record a planetary model's features from a distance. They relate this activity to scientists' space exploration...

Young scholars build and observe a simple aneroid barometer to discover changes in barometric pressure and weather forecasting. They graph changes in barometric pressure for two weeks and make weather predictions.

Middle schoolers investigate the effect of weight on normal friction or the friction due to surface roughness. They tell about the effects of contact area that occurs as a result of molecular attraction by looking at data on line graphs.

Students determine location by using the technique of triangulation. They imagine that they are out in the wilderness and have come to the top of a ridge. How can one identify the ridge on the topo map? How can one figure out where you...

Students conduct an experiment to determine the percentage of sugar in various types of gum. They weigh the gum after chewing it to determine the amount of mass lost from each piece of gum, analyze the data, and create a graph of the...
