Are electric motors all they're cracked up to be? Scholars take a stance and use their knowledge to discuss the benefits and disadvantages of the motor as the first question in a series of four. The questions that follow ask about other...

Pollution is a real concern in most areas of Earth. A four-question AP® assessment has learners analyze data related to water pollution and air pollution as well as consider the pros and cons of recycling. Each question has several...

What's in the water? Encourage your class to further explore this question and learn about pond ecosystems, food chains, and food webs as they complete this hands-on activity. They view the environment from a new perspective...

The tide will turn in your earth science or oceanography unit when viewers see this clip. They learn that tides are caused by the gravitational pull of our moon, and are even impacted by the gravity of the sun. High, low, neap, and...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

Students illustrate the chemical differences between surface and tap-water. They investigate the common chemical and physical parameters relevant for water quality and gain hands on experience with water quality testing. They enhance...

Students investigate the distribution of the earth's water. They conduct a demonstration of water distribution, and create a pie graph to display the results.

Students research water clocks online, investigate how water clocks work, and construct water clock that will keep time accurately for at least two hours without human intervention.

Students research a given nation and complete an activity chart for that country.   In this water crisis lesson students work in groups to organize and present the information for their given country. 

Young scholars use the example of natural water purification to show that healthy ecosystems provide services to people that are essential to life as we know it.

Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

In this science instructional activity, students find the words that are associated with the water found in our environment. The answers are found at the bottom of the page.

Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Students conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Assign ecologists one of five countries that struggle with access to clean water. They research the water crisis in that country and then present information to classmates. A handout was designed for each country, and a worksheet on...

Students identify ways to conserve water. In this environmental lesson plan, students use a water use checklist to identify how much water they use in one day. Students analyze the data and brainstorm ways to conserve water.

Get your scientists engaged in both recall and life application responses after reading a selection from a McGraw Hill science text (not included). Based on chapter 14, this water pollution worksheet has students review where water...

Second graders investigate the water cycle. In this water cycle lesson, 2nd graders discover how the water cycle effects erosion and weathering. Students create their own terrariums to view the water cycle. Students illustrate their...

Students are introduced to the water cycle and water movement in soil. In this water cycle lesson, students explore how water moves through the water cycle and discuss water sources, natural reservoirs, soil...

Students explore the properties of water. In this cross curriculum art and physical science instructional activity, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Students create...

Students investigate the 3 states of matter. In this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data, and...

In this science worksheet, students collaborate as a group of 4 to conduct a science investigation about the water cycle. Students read about the specific job responsibilities for each team member and record their findings on this sheet.
