ocean zones lab report
instructions: in the ocean zones lab you explored organism adaptations that them survive best in a particular habitat and observed how changing some of the factors in the ocean affect the organisms that live there. record your observations in the lab report below. you will submit your completed report.
(30 points possible)
name and title: (1 point) j
objective(s): (2 points)
in your own words, what was the purpose of this lab?
the purpose of this lab was to learn how the different zones of the ocean have different traits and how those differences affect how the separate organisms heal
hypothesis: (5 points)
write your hypothesis by completing the if/then statements below for each of the 5 trials.

• trial 1: anglerfish in high light levels vs. low light levels
if the light in the habitat is increased, then the anglerfish will have a (higher/lower) health rating.

• trial 2: anglerfish in high-pressure levels vs. low-pressure levels
if the pressure in the habitat is increased, then the anglerfish will have a (higher/lower) health rating.

• trial 3: anemone in high salinity levels vs. low salinity levels
if the salinity in the habitat is increased, then the anemone will have a (higher/lower) health rating.

• trial 4: anemone in high ph levels vs. low ph levels.
if the ph in the habitat in increased, then the anemone will have a (higher/lower) health rating.

• trial 5: narwhal in high temperature vs. low-temperature levels
if the temperature in the habitat is increased, then the narwhal will have a (higher/lower) health rating.

procedure:
in this lab, you will meet three marine organisms who are searching for just the right habitat. look at each one’s profile, then predict what type of environment it would prefer. you will then conduct multiple trials.

for each one, you will write a hypothesis showing how an independent variable will affect the dependent variable (the health of the organism). you’ll be able to test your hypothesis in controlled aquarium settings and collect some data and observations for your report. each trial will show the health rating of the organism, which uses data about their activity and respiration to generate a number between 0 and 10, with 10 being the best health.
data: (10 points)
record the health meter reading in the table below for each of the trials, and then record your observations of the organism's behavior.

trial hypothesis independent variable health reading behavior observation
trial 1: anglerfish high light = 10 lux

low light = 2 lux
trial 2: anglerfish high pressure = 100 atm

low pressure = 10 atm
trial 3: anemone low salinity = 28 ppt
high salinity = 36 ppt
trial 4: anemone high ph = 8.3
low ph = 6.7
trial 5: narwhal high temperature = 18°c
low temperature = 4°c

conclusion: (12 points)
your conclusion will include a summary of the lab results and an interpretation of the results. write in complete sentences.
1. how did your hypotheses compare to the results for each trial?
2. which independent variable affected the organism’s health positively in each of the trials? why do you think this occurred?
3. what types of behaviors were exhibited with high health ratings in each trial? what types of behaviors were exhibited with low health ratings for each trial?
4. based on the results in the experiment, what can you infer are the habitat characteristics necessary to provide the highest health rating? explain why.
