Students recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data,...

Students conduct experiments with plants.  In this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

Students diagram a plant. In this Science lesson, students explore the concept of photosynthesis focusing on the oxygen production. Students calculate the amount of plants needed to filter the air in their classroom.

Second graders observe images of prairie ecosystems and discuss the needs of living things. They create a prairie habitat in a closed jar to observe the water cycle and plant growth.

Here is a fantastic, informative, interactive presentation on plant and animal cells. The PowerPoint is produced by an elementary school teacher who has a doctorate in science, and it shows! This would be a splendid presentation to use...

Students work together to build models of prairie plants. Using the model, they estimate the height and then measure them using metric and standard units. They write a fraction to represent their part of the whole set and compare and...

Learners explore elements by analyzing everyday objects and materials in class. In this carbon lesson, students define several vocabulary terms such as carbon dioxide, hydrocarbon, and carbonate. Learners view a group of items,...

Students investigate air by participating in a class experiment. In this matter measurement instructional activity, students identify air as a gas which consists of mass. Students utilize a windsock or balloon to measure oxygen and...

Middle schoolers measure and record their height in centimeters on a graph. By integrating math and science, students collect data and apply graphing skills to the experiences they are having growing plants. Finally, middle schoolers...

Students investigate how all links in the food chain are related. In this animal habitat activity, students hypothesize about what would happen in the food chain if an endangered species were to become extinct. This activity also...

Third graders watch a video on the solar system and examine the role of the sun. As a class, they complete a KWL chart and make different color temperature pockets to use during their experiment. In groups, they make predictions about...

Students compare the efficiency of producing food calories in different types of food then calculate how much land is required to supply their food for a year. They then graph the results.

High schoolers bag trees to determine the mass of the water given off in the evapotranspiration process.
