Young scholars develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Students collect and examine microscopic life from a local pond. In this biology instructional activity, students examine local pond water, searching for protozoa, with the use of a microscope. Students identify the various life forms in...

High schoolers examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.

High schoolers investigate the effects of urban pollution on plankton. In this plankton and pollution lesson plan, students use samples of plankton collected in urban areas to observe the effects of pollution on plankton samples. They...

Students identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

Learners observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...

In this relationships and biodiversity activity, students investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and stems, using paper...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

Photosynthesis was discovered in the 1770s, but chemosynthesis wasn't discovered until 1977. While many have performed an experiment to show how photosynthesis works, the activity allows pupils to observe chemosynthesis. Scholars set up...

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

Students investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on it to...

In this comparing plant and animal cell worksheet, students use a microscope to observe cheek cells and onion cells. They compare their observations and answer 3 questions about their discoveries.

Students discuss scientific advances brought about by the Mars Surveyor Space Program which impact on daily life, identify laboratory apparatus like microscopes, slides and coverslips, and use the microscopes to view cells and organisms.

For this microscope worksheet, students label the parts of a microscope, they calculate the powers of magnification for each lens on the scope and they answer questions about making a wet mount slide.

Students discover the microorganisms that live in water. They study the structures and life functions of protists and recognize the similarities between them and multicellular organisms.

Fifth graders identify function of phytoplankton in the biospere by conducting experiments and simulations and reading for information. They detect the presence of phytoplankton in bodies of water by examining ocean in satellite images...

Students create model coral reefs showing surface area and including examples of communities.  In this coral reef activity, students research and explore the functions or benefits from a coral reef.  Students design a benthic...

Students listen to an explanation of yeast cells and how they effect bread and beer. They discuss the ways alcohol affects the human body and participate in an indirect observation about cell respiration in yeast-molasses cultures.

Students explore animal characteristics by participating in an environment identification activity. In this animal habitat lesson, students discuss a range of different wild life and the ecosystems that they are a part of. Students view...

Beginning biologists prepare a sugar solution for yeast cells to live in, and divide it into two different jars. Samples from each jar are viewed with a microscope, and then one jar is placed in a warm environment and the other a cold...

In this microscope worksheet, students review how microscopes work and how early scientists figured out how microscopes could help them with their discoveries. This worksheet has 3 fill in the blank and 7 short answer questions.

Pupils conduct tests of water samples from different sources, such as a local river, tap water, and an irrigation ditch. After determining which pollutants are present in each sample, students hypothesize the possible sources of the...

Students identify protists under a microscope, and using a stopwatch calculate the speed of a protist from a pond water sample. They use distance and time to identify the speed of a protist, and create a distance versus time graph to...

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.
