Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

Fourth graders investigate the life cycle of a tree by researching the Internet.  For this plant life lesson, 4th graders observe The Life of a Tree website and discuss the life of a tree from sprout to death.  Students create...

Students examine how global wind and water patterns aid in the spread of worldwide pollution. In groups, they read articles about the domino effect of pollution and create posters displaying its journey. On blank world maps, students...

Students identify the differences in local soil types and the relationship between soil size and water retention. They are introduced to microenvironmental conditions in ecosystem sustainability.

Students research about how lunar cycles affect living organisms. In this biology lesson, students prepare an oral presentation of their research results and analyses. They explore the forces that affect tides.

Third graders investigate the life cycle of the Monarch butterfly. They experiment with various tools to simulate the mouth parts of insects, conduct research, record their observations of butterflies hatching, write a play, complete...

Students investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

Students investigate relationships between plants and animals and how living things change during their lives. In this life cycle lesson, students split different types of seeds apart to see the beginning life stages of future plants.

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

Fourth graders simulate filtration of water containing contaminates to determine how nature cleans water. They make predictions, report observations, and construct reasonable explanations concerning their outcomes. then connect this to...

Learners determine the density of 1 drop of water. In this determining density lesson plan, students determine the mass and volume of a drop of water in the lab using appropriate lab techniques and calculate the density of a drop of water.

Students participate in a hands-on activity to investigate how water is recycled in a small environment, and determine how water is cycled on earth.

Learners discuss the different types of water found on Earth. They discover why not all water is used for drinking and calculate how much water they use. They create their own water conservation plan.

Students investigate the properties of water. In this states of water lesson, students explore how water goes from liquid to solid and back to liquid again. Students use measurement, observation, and communication to describe the change.

Students explore the parts of a flower and pollination of flowers. In this plants instructional activity, students use an interactive whiteboard to label the parts of a plant and the functions of each part. Students complete a worksheet...

Learners participate in an experiment in which they investigate the factors affecting the levels of nitrates in groundwater. Using examples, they explain the nitrogen cycle and identify the sources of chemical nitrogen fertilizers. ...

Middle schoolers investigate the concept of erosion by water in a problem solving activity. In small groups, they are assigned either sand, potting soil or rocks to construct a mountain that will hold up to a sprinkler can of water...

Young scholars examine different organisms in various marine habitats. They identify any adaptations that have allowed the organisms to survive. They develop an imaginary organism and describe its life cycle.

Students engage in a lesson of investigating the amount of water that is transpired in a one day cycle. They conduct research to find the purpose of transpiration and find information to explain the value to a plant and explain how...

Students investigate the concept of weather and how it is created. They review relevant vocabulary related to weather. Students predict weather given slight background knowledge. The lesson includes background information for the...

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

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...
