Making an Algae Bloom
Students will perform an experiment that models how algae grows in a marine environment. It will involve a variety of science skills and processes that will allow then to think like a scientist.  The experiment will allow students to form simple procedures, hypothesize,analyze, observe and draw conclusions about those things that affect the water of the Inner Harbor.
Students will:
1. conduct an experiment using various science skills and processes.
2. perform an experiment that stimulates how algae affects the conditions of the Inner Harbor.

Making an Algae Bloom
Prelab Question: Can algae grow if optimal abiotic condtions are present?
1. Divide the students into small groups of four.
2. Provide groups with listed materials.
3. Label each contianer - Container #1- Nutrients and Container # 2- Control
4. Measure 500 ml of water and add to each container.
5. Add five drops of algal culture to each container.
6. Cover container labeled "Control" with a piece of foil.
7. Add five drops of liquid fertilizer to nurtient container.
8. Cover container labeled "Nutrients" with a piece of foil.
9. Place both containers in a sunny window for light exposure and temperature. ( The same areas assures that the abiotic factors are the same.)
10. Make observations dail for one week and record on data table. (See Attached)
