How do you test for algae growth in a science project?

You can place bottles in different amounts of sun to determine how much sunlight is ideal for algae growth. Instead of testing algae, try using duckweed, a small green plant. Duckweed is ideal to test because you can actually count the number of plants that grow under your various conditions.

How do you grow algae in a bottle?

Add equivalent amounts of algae to two (clear plastic) bottles of purified water. Discard the bottle caps. Add two drops of 10-15-10 liquid plant food to each bottle. Pour out a small amount of water from a third bottle of purified water, leaving about an inch of air space at the top of the bottle.

Can algae grow in water bottles?

Algae growth is a common summertime nuisance. These microscopic organisms like to latch onto crevices in well-worn returnable bottles. The sunlight and warmer temperatures can cause algae to flourish in a bottle of water. Even though the bottles go through the wash cycle, the organisms are very resilient.

Does algae feed on fertilizer?

When you use algae as a fertilizer, it quickly begins to break down releasing its abundant nitrogen source. As a result, algae can act as an excellent fertilizer that can be used to help grow crops efficiently.

How to test algae growth for a science fair project?

Label one bottle “Control” and the other “CO2,” for carbon dioxide. Add equal amounts of algae to each bottle. Pour purified water into the third bottle, leaving an inch of space at the top; label this bottle “Reactor,” as you will use it as a carbon dioxide reactor.

Where did the algae science project come from?

Project adapted from: “Eutrophication Lab” D. Gioffre, Hillsborough Middle School, Hillsborough, NJ 08844Funded by the National Science Foundation, Biocomplexity in the Environment Program, Award #0120453 Education.com provides the Science Fair Project Ideas for informational purposes only.

What to do in the Environmental Science Fair?

In this environmental science fair project, you will experiment with the effect of different concentrations of fertilizers on algal growth. Grow algae in several concentrations of fertilizer and observe its effect on algal growth. Share your story with Science Buddies!

How does the algae in a bottle experiment help students?

At a college level, the experiment will introduce biology, oceanography, ecology, and environmental biology students to photosynthesis, aquatic productivity, food webs, carbon cycling, alternative fuels, sustainability, and carbon capture methods in a lecture or lab setting.
