For this plate tectonics worksheet, students review concepts such as the types of plate boundaries, the concept of continental drift, sea-floor spreading, earthquakes, and plate tectonics. They match 30 terms with their definitions.

Students investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.

In this salinity activity, learners simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

Students will use everyday items and speeds to describe the dimensions of a massive flood that occurred in the Pacific Northwest near the end of the last ice age.

Students explore force and motion through a series of experiments. In this physics instructional activity, students create and interpret speed graphs. They build an electromagnet and explain the factors affecting its strength.

Learners explore Wisconsin's natural and cultural history through hands-on exploration of Upham Woods. They are shown the basic paddling skills and they work in teams to paddle across the river on barge. Students describe cultural...

For this reading comprehension worksheet, students read a short text about living in space. Students then answer 6 multiple choice questions about the story.

For this living in space reading worksheet, learners read a passage about life on the International Space Station written by a former astronaut. Students then answer 6 multiple choice questions.

In this earth science worksheet, students read a poem about the wind and learn why the wind blows. After reading the poem and informative paragraphs that follow it, students answer 2 questions regarding the information they read....

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 engage in a lesson plan that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to...

Students use a coffee cup to demonstrate weightlessness. After a lecture/demo, students read an article on free-fall. They perform a simple experiment which helps them explain the concept of weightlessness.

Fifth graders explore how coral polyps increase the chances of egg and sperm meeting after being released into the vast ocean waters.

Students explore rotating frames of reference, focusing on the weightless environment in space and the Coriolis force.

Students explore the concept that free-fall eliminates the local effects of gravity. They discuss what an Earth-orbiting spacecraft experience is like as well as the terminology of weightlessness. Their lab experiment commences.

Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

Students investigate gravity.  In this weightless lesson students complete a lab activity about how a free fall might effect how one perceives gravity.

Sometimes, against a uniform, bright background such as a clear sky or a blank computer screen, you might see things floating across your field of vision. What are these moving objects, and how are you seeing them? This video explains...
