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

Nitrogen Cycle-Stream Side Science
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...
Curated OER
Biosphere II
Students continue their examination of the existence of life on Earth. In groups, they determine the role of the water cycle and other biogeochemical cycles play in keeping balance on Earth. They participate in experiments to discover...
Curated OER
Mosquito Life Cycles
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...
Curated OER
Water Cycle in a Bottle
Students study the water cycle. In this water science lesson, students complete a water cycle experiment using soda bottles.
Curated OER
Water Cycle Column
Students use common materials to construct a working model of the water cycle. They then observe and explain evaporation, condensation, precipitation and percolation as aspects of a continuing cycle. Students also complete worksheets and...
Curated OER
Water Retention and Soil Variation in Local Ecosystems
Young scholars 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.
Curated OER
Fertilizer Frenzy
Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.
Nuffield Foundation
Nitrogen-Fixing Bacteria in Root Nodules of Leguminous Plants
Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.
Curated OER
The Seed Store
Students investigate the seed cycle. In this plant biology lesson, students plant tomato seeds and observe the plant growth. Students complete an activity sheet.
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
What is a Karst
Students investigate landforms by holding a class experiment. In this topography lesson, students define the word "karst" and discover why sinkholes are created on the surface of the Earth by completing worksheets. Students create a...

Viruses
Germs, parasites, and viruses, oh my! Facilitate a instructional activity on viruses as individuals explore functions of Archaea, Bacteria, and Eukarya. They learn how viruses compare with other organisms in nature and how they...

WET Science Lesson #3: Comparison of Aquatic and Terrestrial Plants
Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...
Curated OER
Population Growth
Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...
Virginia Department of Education
Go with the Flow
How does nature's hierarchy relate to our local human environment? Answer this question, along with others, as the class visually depicts the natural hierarchy provided by nature. Pupils discuss each piece of the pyramid and its energy...
Curated OER
The Artemia Hatchery
High schoolers, in groups, develop their hatcheries, working cooperatively in its design and construction. The lessons begin with the introduction to Artemia as a primary food source of many aquaculture species during their larval stages.
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Population Dynamics of Growth of Drosophila
Students experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...
Curated OER
Population Dynamics of Growth of Drosophila
Students investigate population dynamics such as variation in density of females, composition of food sources an environmental factors such as light and temperature on Drosophila. They then relate their findings to human populations and...
