Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires,...

Students learn about the importance of dams by watching a video that presents historical and current information on dams, as well as descriptions of global water resources and the hydrologic cycle. Students also learn about different...

This is a performance task for Grade Four students where they observe two different pendulums and compare the two types of motion. The activity is designed for a lab setting where students work at individual stations. A rubric and...

Examine the link between molecular motion and energy. Observe the movement of a molecule at room temperature. Learn about the different types of molecular motion.

Students explore how tension and compression forces act on three different bridge types. Using sponges, cardboard and string, they create models of beam, arch and suspension bridges and apply forces to understand how they disperse or...

Team lesson focuses on the different types of simple machines, how they work, and how they can be found in daily life.

Students' use a motion detector to examine how different types of motion affect the shape of the distance versus time plot. They explore how changes in direction and other factors affect the shape of the plot.

Explains the different ways that metamorphic rocks can form. Looks at high temperature, high pressure, and chemically active fluids. Discusses structures created in metamorphic rocks by different forces and the classifications based on...

Students discover the different types of reactions, and the driving forces behind those reactions. They learn how to write net ionic equations, and learn about specific types of reactions like acid-base neutralization and...

This lesson allows students to construct a rocket launcher that can be used for several different types of rockets. This rocket launcher is propelled by students stomping on a two liter bottle to provide force.

This well-written article explains what competition in an ecosystem is and the different ways it can manifest itself. It also looks at how organisms avoid competition, some disadvantages and outcomes of competition, the impact of a...

Thirty interesting facts about World War 1 include the causes of the Great War, the American Expeditionary Force (AEF), the countries of the Allies and Central Powers, the American troops, WW1 weapons and the different types of warfare...
