Grow Your Own Algae!
Develop a model of a wastewater treatment center. The last activity of the unit has pupils mix a lake water sample into a tank of water containing fertilizers. Over time, the algae from the lake water grows and removes the nutrient-rich...
Curated OER
Land Plants and Algae
Students compare and contrast algae and land plants. In this plant lesson students discover what algae and land plants require for growth. The students discuss experimental design. The students experiment with different treatments of...
Illustrative Mathematics
Lake Algae
Introduce learners to exponential growth with this real-world problem about algae that is rapidly spreading across a lake in a city park. The task presents the rate of growth and an end value and asks learners to determine what happened...
Curated OER
Algae Blooms
Your microbiologists explore a changing algae population and build an exponential function modeling algae concentration from the description given of the relationship between concentrations in cells/ml and days of rapid growth.
Curated OER
Algae Experiments
Students describe the characteristics of algae. In this biology lesson, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.
Curated OER
Algae--Where does it Live?
Students discover algae. In this science lesson plan, students examine what green algae is and where it grows. Students test the growth of algae in four different types of water: lake water, well water, distilled water and tap water

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
The Marvels of Mud
Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine the role that...
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
High schoolers determine the physical and chemical factors that affect plant growth. In this biology lesson plan, 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
Tracking Ocean Ecology
Students look at the data maps given to them about how chlorophyll affects the algae blooms and make predictions about the harm they will cause. In this data maps lesson plan, students manipulate data sets from the website.
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.
Curated OER
Biomanipulation
Young scholars explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.

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...

Let it Grow and See What Happens
Students 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...
Curated OER
Eutrophication
Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...
It's About Time
The Nitrogen and Phosphorous Cycles
How do we affect the ecosystem, and what can we do to preserve it? Pupils explore chemicals that promote and inhibit plant growth, then discuss the importance of nitrogen and phosphorus to the survival of organisms and describe how...

Measuring Exponential Growth
Middle schoolers reinforce math skills while learning about best practices
for protection of water quality in the management of animal feeding
operations. They make a table to show results of their calculations and compare and justify...

Effects of Nitrate and Phosphate Changes on the Growth of Algae
Students 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
Young scholars 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...
