Description

Ocean’s Impact on Weather Instructions: In the Ocean’s Impact on Weather Lab, you explored the effects of restoring mangrove habitat compared to natural mangrove regrowth following a natural disaster. Record your observations in the lab report below. You will submit your completed report. (30 points possible)

Name and Title (1 point) Include your name, teacher’s name, date, and name of lab.

Objective(s) (2 points) In your own words, what was the purpose of this lab? The purpose of this lab is testing if the restoration project restores it better then the natural way

Hypothesis (2 points) Identify the independent and dependent variables in your investigations. Independent factor is the mangroves the dependent factor is the restoration team State your hypothesis. If I replant the mangroves myself in the north beach, then the north beach will repair faster then the south beach

Procedure At the north beach, your team will implement a project to replant three mangrove species and monitor their growth over five years. The growth of the replanted mangroves will be compared to the natural regrowth of mangroves in the south beach area. Mangrove growth in both beach areas will be monitored via satellite. You will record data for each location about the percentage of mangrove coverage, the number of species in the area, and the average mangrove height in order to assess the health of the beaches.

Data and Analysis (16 points) Complete each table below by recording the collected data, and then create graphs to display the data.

Percentage of Mangrove Coverage

Before hurricane Immediately after hurricane damage 6 months post hurricane 1 year post hurricane 2 years post hurricane 3 years post hurricane 4 years post hurricane 5 years post hurricane

North Beach 90% 2%

South Beach 100% 2%

25% 30% 45% 50% 70% 80%

20% 30% 40% 50% 60% 80%

North Beach 54 21

South Beach 59 30

25 31 36 39 44 51

34 37 43 45 49 55

Number of Species

Before hurricane Immediately after hurricane damage 6 months post hurricane 1 year post hurricane 2 years post hurricane 3 years post hurricane 4 years post hurricane 5 years post hurricane

Average Mangrove Height After Five Years (in meters)

Red Mangrove Black Mangrove White Mangrove

North Beach 4.2m 3.7m 3m

South Beach 5.1m 4.4m 3.7m

Create a graph to display the mangrove coverage from the first data table. It should be a line graph showing percent coverage over time and have two lines of data points on it, one for the north beach and one for the south beach. Title and label the graph. (3 points)

Create a graph to display the number of species from the second data table. It should be a line graph showing the number of species over time and have two lines of data points on it, one for the north beach and one for the south beach. Title and label the graph. (3 points)

Conclusion (9 points) Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer in complete sentences. 1. Was the restoration project effective? Explain why or why not, supporting your answer with information from your data tables and graphs. Yes in the beginning was effective because during the restoration project north beach had higher percentages of mangroves growing back then south beach did. However at the end the restoration project was somewhat effective after 5 years south beach had an 80% mangroves restored and north beach had the same percentage with 80 % of the mangroves restored in addition South beach had 55 species after 5 years while north beach only had 51 species 2. Why was counting the number of species in the area important? In your answer, consider the effect a mangrove habitat has on biodiversity. Counting the numbers the numbers of species in the area is important because it shows us how much the hurricane really affected the wildlife secondly its important because it show how much the hurricane damaged the north and south beach, the mangrove effect on biodiversity is the

major loss in mangroves is the major loss of biodiversity and the more mangroves in one area is the biodiversity there is

3. After five years, the average height of each mangrove species was also measured. Did this information help you better evaluate the success of the restoration project, or did it change your mind? Explain your reasoning.

Yes after seeing the height of the mangrove trees it helped me when deciding if the restoration project was a success. The results from the project are only 3m In the north beach whereas in the south beach they have an average height of 3.7m in conclusion we can see the restoration project wasn’t as successful as planned in my hypothesis...
