Students discuss pollution and the steps in the hydrologic cycle. They follow a drop of water through a watershed simulation. They discover the components of a water cleaning system as well.

Learners select one of the ideas for a science project reflecting their knowledge about coal. They then choose a catchy title to spark interest that describes their project. They use the scientific method to explain the process.

Students relate the states of matter and clouds.  In this environment instructional activity, students create a chart of information they know about clouds.  Students put an ice cube in a bag and tape to a window. Students...

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle instructional activity, learners calculate how much water leaves produce from a whole tree. ...

Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Students see that spiders have a life cycle, and reproduce by laying many eggs. We can count by ones, twos, fives, or as many as we want. They make two lists of animals on a chart.

Students, operating under simulated budget constraints, build pop-rockets and launch them. Working in pairs, they complete budget worksheets and use their "Blast Off Bucks" to pay for the construction. They then redesign their rockets...

The "Engage" section of a wetlands lesson plan asks young ecologists to examine a wetlands poster. You can easily find one online and display it using a projector. Pupils immerse a piece of sandstone and a piece of granite in water to...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Students explore the pollination cycle. In this pollination activity, students investigate the process of pollination. Students illustrate the pollination cycle of bees on paper plates.

Young scholars conduct an experiment. They review how to use the scientific method to conduct an experiment with white carnations and food coloring. They create a hypothesis and test it to better understand how plants get nutrients,...

Students explore the different types of pollution. they conduct experiments using dye mixed with tap water to measure the levels of dilution. They discuss at what point the dye (pollution) would be diluted enough to be safe to drink.

Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.

Young scholars explore the life cycle of shrimp. In this life cycle lesson, students research the different stages of a shrimp's life cycle. Young scholars examine threats to the species in each stage of life.

Students sequence the steps leading to the formation of rain, and design a model to represent these steps. This task assesses students' abilities to classify, generalize, infer, interpret and communicate data, and construct a pictorial...

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Learners discover how the "drinking bird" functions. In this investigative lesson, students discover what makes the drinking bird drink by analyzing relative humidity, temperature, and barometric pressure.

Students identify rock classifications and rock cycles.  For this rocks and soils lesson students complete experiments on rocks and how they are symbols in the Bible. 

Junior geologists, hydrologists, or meteorologists simulate what happens during the flooding of a river and demonstrate factors that contribute to flash flooding. This outstanding resource provides a vocabulary list, online resources,...

In this physical oceanography PowerPoint, viewers learn about ocean circulation, sea surface temperatures, and salinity. Relationships among these aspects are explained, as well as their impact on the atmosphere and climate. Each slide...

For this fresh water worksheet, students click on the links in the questions about fresh water to find the answers and then come back and answer the questions. Students answer 9 questions total.

Students examine the differences between snow and rain. In this precipitation lesson, students measure one inch of rain and snow to calculate the amount of liquid water. Students use a snowfall "conversion" chart to measure how much...

Students examine sunflowers and discuss the importance of sunflower cooking oil and seeds. They view pictures, read books, sing sunflower songs, and grow flowers from sunflower seeds.

Sixth graders create designs for salmon habitats. They work in groups to design a tank habitat that mimics the requirements for salmon in various phases of its life cycle. Students may also raise salmon eggs as part of this unit.
