Here is a fascinating instructional activity about the life cycles of plants and animals, and other cycles found in nature. Learners explore the cycle of the moon, the tides, and other sequences of events in every day life. The big...

A thorough background and nitrate sampling lab sheet are provided to share with your young scientists. After discussing the nitrogen cycle with the class, you will break them into small groups and show them how to use their inquiry...

An educational instructional activity focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Why read about it when you can watch it happen? Bird cams make it possible for learners to experience the life cycle of a bird in real time! An engaging set of lessons provides activities to connect their learning to bird cam...

Students gather mosquito eggs to record the mosquito life cycle using drawings, descriptions, and any other appropriate means. In small groups, they analyze and describe the process of complete metamorphosis. They classify mosquitoes...

Students create terrariums in containers in order to study the Water Cycle. They examine how the terrarium maintains life in the closed environment.

Observe onion root cells undergoing mitosis underneath a light microscope and determine the phase of mitosis the cells are in. High schoolers draw a sketch of the mitotic cells, explore why cells undergo mitosis and learn how...

The goal of this science instructional activity is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and...

Identify the different stages of mitosis and what occurs in each stage with a straightforward biology lesson. Young scientists identify the importance of the cell cycle control in maintaining homeostasis, and then match the correct...

Young scholars investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.

Students observe the life cycle of the Drosophila fly as well as manipulate large numbers of flies, determine the difference between the sexes, and identify the different stages of the fly's life cycle.

Fourth graders explore the plant life cycle. They discuss the sequence of events in the life cycle of the plant and illustrate how the life cycle never ends. Students explore the importance of water, sunlight, and nutrients during the...

Third graders examine and compare the life cycles of a variety of different animals. They analyze photos of animals and discuss any unique body parts and why those parts function they way they do. Next, they observe mealworms and...

Students explore biology by researching ocean statistics. In this data analysis lesson, students conduct a snail examination experiment utilizing live pouch snails. Students collect data about the snails over the course of six weeks and...

Students study the stages of the water cycle and evaporation. In this water cycle lesson, students read Water Cycles and color a diagram of the water cycle. Students review related terms and sing a song about the Water Cycle. Students...

Ninth graders evaluate the use of radiation in medical procedures. In this biology lesson students compare and contrast meiosis and mitosis. They research the different applications of radiation.

Fifth graders identify the chemical and physical changes in the water cycle, carbon cycle, and the effects of weathering. They analyze the periodic table, and observe how vinegar reacts with limestone in a chemical reaction that causes...

Middle schoolers analyze an animal's life cycle and behaviors, and examine what animals need to stay alive and reproduce. They develop theories and hypotheses about the reasons for migrations, using the Journey North online project.

Students identify and explain the parts of a flower and their role in the life cycle of flowering plants. In this online plant biology instructional activity, students explore the processes of pollination, seed dispersal, and...

Young scholars identify the different biogeochemical cycles on Earth. In this biology lesson, students observe microbes under a microscope. They compare and contrast respiration and photosynthesis.
