Students investigate the process of hydroponic agriculture. They grow beans in different hydroponic solutions, compare results and graph their observations.

Explain the coagulation and coalescence processes associated with milk protein and cheese. List the components of milk and explain how each component is dispersed in the milk. Describe what happens when milk protein is coagulated Discuss...

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

Explain the coagulation and coalescence processes associated with milk protein and cheese. List the components of milk and explain how each component is dispersed in the milk. Describe what happens when milk protein is coagulated Discuss...

What does it mean to grow? To germinate? For the plan detailed here, class members investigate the growth process of an oak tree while focusing on the beginning stages of planting and germination. They plant seeds and record observations...

Students examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden increase...

Students explore the process of decomposition. In this ecology and measurement lesson plan, students prepare a worm home to be used for vermicomposting. Students weigh a group of worms and the added food, recording this information on a...

students analyze the place of humans among the tropic levels by observing what we eat. They calculate the caloric content of several foods commonly eaten by humans and calculate the total energy cost to grow, process, transport, store...

Students gain an enhanced understanding of the relationship between proper nutrition and good health. Through use of video, hands-on activities and interaction, students measure energy in food, and recognize sources of vitamins and...

Seventh graders trace a piece of food through the digestive system. They describe the functions of the mouth, esophagus, stomach, etc.

Seventh graders trace a piece of food through the alimentary canal and differentiate between mechanical and chemical digestion in several different hands-on activities related to digestion.

Third graders create a map showing the journey of rice from the field to the grocery store.  In this agriculture lesson plan, 3rd graders discover and map the process of harvesting and preparing rice to be packaged and shipped to...

Second graders discuss worm composting. In this decomposition lesson, 2nd graders look at the anatomy of the worm and how it eats food. They have their own worm bin and review what foods can and can not be given to the worms for...

Students explore the process of decomposition in plants. In this plant biology instructional activity, students use a cleaned out pumpkin and observe how the decomposition process takes place. Students write down adjectives to describe...

Learners analyze the trophic level of humans by first calculating the kilocalories in own their lunch. They then calulate the kilocalories in a wide variety of foods found in grocery stores and compare the kilocalories needed to acquire...

Students investigate how plants transport water and nutrients through the plant. In this transportation in plants lesson plan, students use glass tubing, celery stalks, food coloring and leaves from plants to observe adhesion and...

Young scholars explore the process of decomposition. In this science lesson, students carve a pumpkin and observe as it decomposes. Young scholars compare the changes to an uncarved pumpkin. Students write about the disappearing pumpkin.

Students investigate the composting process through a variety of experiments. For this ecology lesson, students discuss the benefits of composting. They examine how compost affect plant growth.

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Students create a definition of eutrophication.  In this organic material lesson plan students work together to create a storyline.

Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.

Seventh graders investigate nutrients and nutrition to determine what types of food the body needs for energy. They study each type of nutrient and why it is important to the body. They determine what a balanced diet is by completing the...

Students explore nutrition. In this science lesson plan, students identify and describe the main nutrients in our diets that are needed by the body as a source of energy.

Students explore the various components of the digestive system and learn about both the physical and chemical processes that work together to break down food into absorbable molecules.
