Students explore the concept of environmental stewardship. In this science instructional activity, students examine the environmental effects of oil spills as they replicate a contained oil spill and clean up.

Students participate in a variety of experiments designed to illustrate types of heat transfer including conduction, convection and radiation. They complete worksheets as an assessment of the experiments.

Students investigate the dirt in the air. In this air quality activity, students use aluminum foil and petroleum jelly to discover if there is dirt in the air. Students discuss results.

Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...

This is an educator's guide for a unit on things that sink or float. It includes lesson plans, experiments, and activities. Students apply the scientific method as they investigate whether objects sink or float.

Throughout the activities in this investigation, students may have wondered how a boat made out of steel, which is more dense than water, can float. This activity addresses that question. Students will see that changing the shape of an...

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the activity, students will understand that density and weight are different and that density matters in floatation. They...

Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

Students find the densities of objects based on sinking or floating in this activity that demonstrates Archimedes Principle.

Students experiment with items that sink or float, and learn that water's density is equal to one, and objects/solutions with a density greater than one will sink, and those with a density less than one will float.

Students investigate with common objects to see if they can make something that neither floats nor sinks, but rather "flinks" in the middle.
