STABLE ANGLES OF SLOPES

Seventh graders identify variables and controls in a paper airplane investigation. In this scientific method lesson, 7th graders conduct an experiment to determine the variables that affect the flight of paper airplanes. They design an...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

A great lesson introduces your youngsters to electricity. They use internet links, streaming video, and engage in hands-on activities to understand what electricity is and how it works. They build a circuit board, and construct a variety...

Students explore the active layer above permafrost and investigate various factors on the insulation value of the active layer.  In this energy transfer lesson plan, students conduct and experiment to determine the effects of snow...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Go fly a kite, then fly a plane! The 19th part of a 22-part unit on aviation looks at the way kites and gliders help aid in the understanding of flight. Pupils discuss how engineers used kites to influence airplane designs.

Students examine how river travel affected the Lewis and Clark expedition. They define gravity, slope, and velocity, conduct a river formations experiment, complete an activity sheet, and watch a video about Lewis and Clark.

Learners investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...

Students examine the different ways heat can be felt.  In this radiation and conduction lesson, students recognize that the sun radiates heat. Students conduct three experiments to find how the sun warms the Earth and how that heat...
