Description
Lesson 2
Activity 1: Contamination Effect on Sea Life
In teams, investigate the effect of fertilizer contamination affecting water and sea life. Look specifically for the effect of high levels of nitrogen and phosphorous.
Appoint a recorder to take notes so that the team can build a body of evidence that can be used in the next activity.
Activity 2: Educating the Public
Team share their flyers on environmental factors affecting sea life, particularly fish and crabs.
Members critique each flyer and decide on what is accurate, what the public needs to know, and what other information is important.
Then make a 2 minute Public Service Announcement that includes:
- The problem
- Possible causes based on evidence and research
- Recommendations to Public
- Hope - end on a high note that shows what is being done or what individuals can do to decrease the problem.
Activity 3: Case Study
Complete the case study, Tuna For Lunch?
NOTE: These activities may be substituted with others that meet the needs of students at the discretion of the instructor.

ENVIRONMENTAL FACTOR AFFECTING SEA LIFE

Activity 1: Contamination Effect on Sea Life
Most fertilizers are either nitrogenous or phosphates this fertilizers generally have
immense disastrous effects on the environment since in situations of excessive concentration of
nitrogen fertilizers most aquatic life is negatively affected. In a nutshell, this fertilizers lead to
the depletion of oxygen which supports life so most of the marine life dies. Secondly this
fertilizers support the growth of algae which leads to suffocation of aquatic life.
Activity 2-Educating the Public
1. Environmental factors affecting sea life particularly fish and crabs.
It is quite evident that nutrient pollution has spread widely in America, making it one of
the most costly and challenging environmental problems. It is mainly caused by excess nitrogen
and phosphorus in water and in the air. Nitrogen and phosphorus sustain aquatic plants and
algae, which supply food and home for fish, crabs and other microorganisms that live in water.
When too much nitrogen and phosphorus go into the environment, the air and water can be
polluted affecting river streams, lakes and coastal waters which in turn results to serious
environmental and human health issues. In addition, too much nitrogen and phosphorus in water
enables algae to grow faster than the ecosy...
