Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Young scholars investigate how water goes from a solid to a liquid then back again.  In this experimental lesson students conduct their own experiment and see how water changes form. 

Students explore water and ice. In this physical science lesson, students participate in a science inquiry and observe the characteristics of ice and water. Students compare the differences between a solid and liquid and record their...

Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

The blue king crab and the red king crab live in the same range but never in the same region. The third lesson in the series of five focuses on the blue king crab and the impact the changes in water temperature is having on its...

Elementary schoolers study the geographic location of the Sonoran Desert. They pay close attention to the characteristics of the plants and animals found in this desert environment. The student handouts embedded in this plan are...

Eighth graders are introduced to the Earth's hydrologic system including the cycling of water in the atmosphere and the movement of water on the surface of the planet using the Great Lakes watershed as an example.

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Students discover the forms water can take. In this hands-on science lesson, students examine how water can change from a solid to a liquid and then back again.

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

Students explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing lesson,...

In this science worksheet, students read about the Hydrologic Cycle. Students use the reading and a diagram to answer 2 comprehension questions.

Students explore cycles in nature. In this cross curriculum agriculture lesson plan, students define "cycle" and research weather and planting folklore. Students make a bracelet in which individual colored beads represent the many...

Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson plan, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific...

In this rock cycle worksheet, students use different colored crayons to represent different types of rocks. They follow step by step procedures to model the rock cycle with the crayons. Students draw the rock cycle, show weathering,...

Middle schoolers identify and describe the steps in the water cycle. They discover the sun as the source of the cycle. They work together to create their own water cycle model.

For this water worksheet, students review the steps involved in the water cycle. This worksheet has 9 fill in the blank and 3 short answer questions.

To conclude their examination of forest ecosystems, class members consider the role forests play in the carbon cycle and how forests can offset climate change.

Fourth graders explore evaporation and condensation. In this water cycle lesson, 4th graders investigate their surroundings for real-life examples of evaporation and condensation. Students conduct various experiments.

Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.

A teacher with talent has created a fun set of review questions on the changing states of matter. Cycle through 15 questions, multiple choice answers, and a monetary reward for guessing correctly. Use this game show PowerPoint to help...

Focused little scientists will flitter their arms back and forth across the room with excitement as they learn the life cycle of a butterfly and how living things grow and change over time.

Young scholars explore forms that water can take and examine the water cycle. In this hands-on science lesson, students participate in activities that require them to change water to a solid and back to a liquid again.
