What are Some Substances That Will Cause Algae To Grow?
Students discover algae. In this science lesson plan, students examine what green algae is and where it grows. Students determine the effects of oil, detergent, copper crystals sulfate and lawn fertilizer have on the growth of algae.
Curated OER
Pea Soup Ponds
Students perform an experiment where they learn how water can be polluted by algal bloom. They grow algae with different concentrations of fertilizers or nutrients and analyze their results.
Curated OER
Factors Affecting Plant Growth
Students determine the physical and chemical factors that affect plant growth. In this biology lesson, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.
Curated OER
Testing Growth of Algae
Students participate in an experiment in which they test the growing rate of algae. They test the algae in different elements recording their observations. They share their results with the class and discuss.
Curated OER
What Are We?
Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.

Phytoplankton and Ocean Color
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...
Curated OER
Let it Grow and See What Happens
Pupils participate in an experiment in which they try to stop algae from growing. In groups, they develop a hypothesis and test it while making changes to the experiment along the way. They make observations and organize their data to...

Effects of Nitrate and Phosphate Changes on the Growth of Algae
Learners determine the effects of an increase of the amount of nitrate and phosphate levels on the growth of algae. the development of a hypothesis is encouraged and students proceed to a conclusion based on their results.
Curated OER
Fertilizer Frenzy
Learners design and conduct an experiment testing the effect of fertilizers/soaps on algal growth. They estimate and predict, identify the variables, formulate a hypothesis, and record and analyze the data, presenting their findings in a...
