Students explain the different stages in the growth of a frog, then analyze and collect data to make generalizations about a larger population. They determine the survival rate of a population of tadpoles under controlled conditions.

Pupils 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.

Students identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Students explain the parts of the body that are involved in breathing and explore lung function.  In this model lung lesson students make a model of a lung then interpret and explain it. 

Learners predict the flow of an oil spill and depict it on a map. They explain the predicted route of the oil spill using knowledge of ocean currents in a short presentation to their peers.

How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson plan....

Wouldn't it be great if you could produce your own food? Scholars learn about the processes of photosynthesis and cellular respiration in plants. They consider how to use photosynthesis as a model of an efficient system and how to apply...

Students explain the effect of water, temperature and light on plant growth.

Students easure and record volume of water, then measure and record mass of soil. They explain the effects of the following in controlling erosion: Contouring, cover crop, strip cropping, reforestation, inter-seeding.

Students investigate the function and purpose of seed dispersal. In this garden lesson, students examine the importance of wind in the plant cycle. Students construct a flying seed model from an attached design and discuss if it can be...

In this science worksheet, students match each of the descriptions on the right to the correct scientist listed on the right. There are thirty scientists to identify and match on the sheet.

Students construct their own diagrams outlining the pathway of carbon and oxygen in the atmosphere. Students explain their diagrams outlining the pathway and teacher checks for accuracy and completion.

Pupils investigate U.S. geography by exploring it's bodies of water. In this river formation lesson, students identify the reasons rivers are needed in our country by reading assigned text. Pupils examine a diagram which explains how...

Students identify different climate regions and local weather patterns.  In this cloud coverage lesson students use NASA satellite data and import it into Excel. 

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...

Fourth graders investigate the significance of natural resources and the habitats of butterflies. They create a list of their own favorite foods, then watch a video about habitats. Students identify things in the video that animals and...

High schoolers discover how toys often illustrate fundamental physical principles. The toy drinking bird is an example. The challenge for you in the lab is to discover why the drinking bird functions.

Students conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.

Students put items in a plastic bag and watch the effects of composting. While completing the experiment, students answer questions and ask permission to start their own compost pile at home.

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.

Students understand the sea ice cycle and can explain its stages. In this Sea Ice lesson, students play a game to identify types of sea ice. Students answer critical thinking questions about sea ice. Students complete a sea ice worksheet.

A little engineering design is mixed into this lesson on precipitation measurement. Groups plan and construct a rain gauge, and use it to collect precipitation. As part of the PowerPoint presentation, learners view a satellite map of...

Fourth graders are introduced to how electricity is produced. In groups, they compare and contrast the linear production of energy with other forms of mechanical energy production. They try to make a turbine work acting like it is part...

Students perform an activity in which they discover what happens when food chains overlap in an ecosystem and discover the three components of a food web.
