Science Fair Project Idea. Scientific Method. Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to use archived data from continuous monitoring stations on the ...
For ninth and tenth grade students, use this activity to model growth rates. For example, place a solar cell under the tank and connected to a voltmeter. As the algae begins to grow, take periodic measurements of how much light passes through the tank. Allow students to create a graph over time of the data they collect and have them explain why ...
Here are some resources to help you! Here are some Lesson Plans: Algae Growing (Google document) Algae Bloom Investigation (Google document) Algae Bloom Experiment (Downloadable PDF) Zooplankton project are really great too: Brainy Briny family of products. Here are some videos: ARS Phototaxis in Brine Shrimp.
When they ocean is green, phytoplankton are abundant. In the experiment, the color inside the bottle provides an indication of the amount of algae. Changes in the color inside the bottle over a period of days indicate how fast the algae are growing. It will be important to observe and document these changes.
4. Experimental Procedure: a) Remove algae beads from the test tube by pouring through the kitchen strainer. b) Use the plastic spoon to place an equal number (approximately 10) of algae beads in all four vials/cuvettes. c) Fill all four vials with algae beads to the top with hydrogen carbonate pH indicator solution.
Preliminary studies show that com-pounds isolated from algae can kill drug-resistant pathogens. "Kind of a neo-Neosporin," says Manning, "Algae don't have teeth and claws, so they're producing a lot of these different compounds as a defense. They're usually just trying to claim their space in the world.".
Summary. The Algae-in-a-Bottle Experiment provides an engaging and flexible high-impact teaching tool for helping students to know, understand, and apply a number of concepts related to the biology and ecology of aquatic plants and their environments. It is also relevant to methods being developed for the use of algae as an alternative energy ...
This effectively traps large numbers of algal cells in 'jelly like' balls made of sodium alginate. Sodium alginate is not harmful to the algae, and they will continue to photosynthesise once immobilised. When these algae are 'wrapped up' in the jelly balls they are excellent to use in experiments on photosynthesis. These algal balls are ...
These toxins have caused health problems, such as lupus-like symptoms and hives for some residents. To understand the causes of this environmental problem, we need to look at the basic chemistry and biology of plant and algae growth. Farmers put un-natural amounts of phosphorous (P) and nitrogen (N) on their fields to grow maximum crop yields.

SCIENCE. Teen's Algae-Biofuel Experiment Wins Science Fest. The winner of the $100,000 Intel Science Talent Search is Sarah Volz, a Colorado public high-school senior who developed a way to increase oil yields from algae, a potential alternative to fossil fuels. Algae's potential as a fuel source is so great, it's nicknamed "green crude
The optimum temperature for algal growth is between 20 and 24 degrees C. Temperatures above 35 degrees C are lethal to algae.) Monitor the growth of the algae in the two sample bottles for one month. If necessary, replace the sugar, yeast, and water in the reactor to keep the carbon dioxide source operating. At the end of the month, compare the ...
Ecology. The algae and pollution experiment is a Biology experiment from the Layers of Learning Ecology unit. Layers of Learning has hands-on experiments in every unit of this family-friendly curriculum. Learn more about Layers of Learning. Algae grows naturally in ponds and is a normal part of the ecosystem of a pond.
Abstract. Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to use archived data from continuous monitoring stations on the Chesapeake Bay to study how water ...
