Humans can have a big impact on the environment, specifically the influence they have on the carbon cycle. First, the class will define and discuss each of the earths four major spheres, the biosphere, hydrosphere, atmosphere, and...

Note the way that plants change during the season by adopting a plant on your school campus. After your class chooses their plant, they research the plant's needs, how it differs from other plants, find ways to support their plant's...

A 22-slide set provides pretty much everything you need to teach the rock cycle except the actual specimens. All of the slides contain graphics or photographs to help describe the process, and most even have links to educational videos....

Crawl into the world of the darkling beetle with this scientific investigation. Watch as the insects move through the larval, pupal, and adult stages of life, recording observations along the way. Discuss the necessities of life as young...

It's an extravaganza of excrement! Do your pupils understand that waste doesn't really go to waste? Introduce the nitrogen cycle with an interesting instructional activity and lab from the K20 series. The activities include a look at...

Learn the science behind ocean acidification and its effects on ocean wildlife. Young scientists conduct a laboratory investigation that monitors the acidity level of water. While burning a candle, learners capture the carbon dioxide in...

Third graders take note of the changes in the water level in a cup of water that is left out. Using a model of the water that depicts a lake and landscape that is being heated by a heat lamp, the students observe precipitation, and...

Students explain the function of the hydrologic cycle and demonstrate how transpiration rates can be experimentally changed.

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.

In this reviewing water and changes of state worksheet, students answer questions about water vapor, state of water, freezing point of ice, evaporation, condensation, distillation, dry ice, and the water cycle. Students answer...

Third graders complete a KWL chart on what they already know about water and what they want to know. As a class, they participate in an activity in which they discover the amount of drinkable water on Earth and are introduced to the...

Students test tap water for hardness and mineral content. In this environmental science lesson, students identify the different stages of the water cycle. They classify plant and animals according to the rules of taxonomy.

Students recognize that all of the water on earth cannot be used for drinking and that the percentage of ground and surface water is a small percentage.  In this water activity students identify ways to conserve water. 

This weather PowerPoint features a game in which students advance to the finish line with a race car as they answer questions related to weather. Topics include types of clouds, weather instruments, the water cycle, and various weather...

Encourage peer collaboration and assist with the creation of visual aids to identify carbon, water, and nitrogen cycles as your class learns more about nature. They discuss relative information, create a visual aid...

Where does the water we use come from? To understand the concept of a watershed, class members study the water cycle and then engage in an activity that simulates a watershed.

This slide show progresses through a comprehensive review of the grounding principles of earth science. Get down and dirty with the details of fossil fuels! Help your geologists to have a rock solid understanding of the rock cycle. The...

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...

How does weather affect Earth? Learners understand the characteristics of water and make predictions about weather patterns. They recognize how water and weather affect rocks and minerals through erosion. They also learn about fossils...

Is everything really connected? Take your class on a walk outside, where they will make observations and write them down on a worksheet. Once they are back in the classroom, learners will work to determine if and how things like birds,...

There are many interactions among living things and their surroundings. By completing a reading, scholars learn about the Earth, the moon, and the sun and how they relate to the solar system. They also investigate the basics of physical...

How does nature's hierarchy relate to our local human environment? Answer this question, along with others, as the class visually depicts the natural hierarchy provided by nature. Pupils discuss each piece of the pyramid and its energy...
