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
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
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
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
Students 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...

Some Like It Hot, Some Like It Cold
Students are explained that thermophiles are organisms that have optimal growth temperatures above 50oC. They investigate the temperature ranges for the growth of common bacteria. Students answer the question of do either of these...
Curated OER
What Are We?
Students describe different types of water pollutants. They complete experiments in which they observe the affects of water pollution on algae. They also brainstorm and list three causes of each water pollutant.
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.
Curated OER
Dissolved Oxygen in an Aquatic Ecosystem
High schoolers explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.
Curated OER
Water Quality and Dissolved Oxygen
Young scholars investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of...
Curated OER
Allelopathy Experiments
Students explore how allelopathy works in plants. In this botany lesson, students explain how this phenomenon affect other organisms. They read and analyze an article about allelopathy and discuss its flaws.
Curated OER
Snow on Sea Ice
Students examine different samples of ice and predict the amount of snow that has fallen in a given year. Using a calculator, they graph the various thicknesses. They analyze the graphs to determine the relationship between the snow and...
Curated OER
Fertilizers
Students examine the nutrient makeup in fertilizers. In this plant nutrient lesson plan students see the effects of common fertilizers on plants.
Curated OER
Where's My Bot?
Students estimate geographic position based on speed and air travel. In GPS lesson students use GPS to estimate the set and drift of currents.
Curated OER
Oxygen Levels and Aquatic Plants and Animals
Students design an experiment to test the effects of a change in the amount of dissolved oxygen of water on aquatic plants and animals. Questions are offered for exploration and experiment design. Results are tabulated and conclusions...
Curated OER
Coral Bleaching
Students examine the relationship between corals and zooxanthellae, identify stresses to corals, and explain coral bleaching. In this sea life instructional activity students predict the effects of increased temperatures on coral reefs.
