Fifth graders observe a diagram of the oxygen-carbon dioxide cycle to know that when they breathe out, they exhale carbon dioxide as do animals. They observe an aquarium containing both plants and fish and discuss the cycle. They then...

Learners examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Learners study the Miller-Urey Experiment including its history and criticism.  In this origins of life lesson students repeat this experiment to see how it works.

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.

First graders grow radishes. In this Science lesson plan, 1st graders observe the growth of radishes in both the light and dark. Students discuss what plants need to live.

Sixth graders define atmosphere and hydrosphere, explore through experimentation how the atmosphere was formed, and describe the layers of the Earth's atmosphere and their distances.

When is the last time pupils did a happy dance in class? Scholars act out photosynthesis and dance excitedly in front of the class. The resource also comes with a worksheet for those waiting or who have already completed the...

Learners experiment to determine which bottle of soda has more dissolved carbon dioxide. For this solutions lesson, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and explain the...

Students explore the Chernobyl incident and the resulting environmental health impacts. They explore three different isotopes that were released into the atmosphere. Through inquiry, students determine the difference between types of...

Students work in groups to research biomass using the International Energy Agency's website. Students use evidence from the web search to assess biomass energy potential in Pennsylvania as part of a classroom "Alternative Energy...

Students study the Krebs's cycle and understand the steps at a functional level.  For this cellular respiration lesson students complete different stations then do a written assignment. 

Students discover how coal is formed. In this science lesson, students create a scrapbook on the life cycle of coal and show how coal is formed by showing pictures of each stage.

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...

Learners discover the harm and benefits of microbes. In this biology instructional activity, students explore water, nitrogen and carbon cycles. They investigate the factors affecting bacteria growth.

Students analyze the energy consumption of a household to see the amount of carbon dioxide they add to the atmosphere each year.  In this energy consumption instructional activity students calculate carbon emissions and discuss...

Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...

Ninth graders complete a unit of lessons on ecosystems, organism interactions, and energy flow. They create a key for known species of fish, diagram the movement of energy through an ecosystem, and create and present food chains and food...

Students identify the physical and chemical properties and explore the differences.  In physical and chemical property lesson plan students test polymers for the differences between the physical and chemical properties, record their...

Students participate in an experiment to define a parts-per-billion solution. In this ecology lesson plan, students select a second substance to create a parts-per-billion solution and observe and record their results. Students work in...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

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 create their own environment. For this environmental protection lesson, students pretend they are the owners of a tropical island. They create jobs for the citizens and develop the island as a model environment.

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...
