PROBLEM / OBJECTIVE

Will the temperature of water affects the Operculum Movement of fish?

variables
VARIABLES
  • Independent variable: Temperature of water
  • Dependent variable: No. of Operculum movement of fish
  • Controlled variable: Volume of Water
materials
MATERIALS
  • 1L Beaker (3)
  • Mercury Thermometer (3)
  • Water
  • Ice
  • Timer
  • Fishes (2)
procedure
PROCEDURE
  • The fishes were placed in a 1000ml beaker with half full tap water.
  • After that, the temperature of the water was measured using a mercury thermometer. The operculum movement of the fishes was recorded for one minute. The procedure was repeated two more times for it to have an exact result.
procedure1
PROCEDURE

3. Ice was added in the 1000ml beaker with half full tap water. Again, the temperature was measured using a mercury thermometer and waited for the temperature to reach 10˚C.

4. The fishes were then returned to the tank.

5. The average number of operculum movements as calculated for each of the three different water temperature trials.

RESULTS AND DISCUSSION

NO. OF OPERCULUM MOVEMENT OF FISH PER MINUTE

results and discussions1
RESULTS AND DISCUSSIONS

After the students have recorded the no. of operculum movement in different temperature of water, It was observed that “the lower the temperature of water, the lower the number of operculum movement of fish.”

results and discussions2
RESULTS AND DISCUSSIONS

In a 30˚C temperature of water, higher no. of operculum movement of fish was observed. In this case, the temperature makes fish breathe at a faster rate because warm water contains less oxygen. In a 20˚C temperature of water, it was observed that the fish breathe not faster than that of the warmer water or the 30˚C water temperature.

results and discussions3
RESULTS AND DISCUSSIONS

However, the operculum movement of the fishes was much slower in a 10˚C temperature than that of higher temperature. Fish can’t live last long in very cold water that they may eventually die. This was the student’s observation based on the experiment.

results and discussions4
RESULTS AND DISCUSSIONS

When the students tried to transfer the fish in a colder temperature, their operculum movement suddenly slows down and stopped. The fish settled at the bottom of the beaker. The students tried to recover the fish. The fish was transferred in the beaker with normal room temperature of water. The operculum of fish started to move faster, but the fish was not exactly in a normal condition. After a few minutes, the fish started to recover and was back at its normal state.

results and discussions5
RESULTS AND DISCUSSIONS

Same as what happened to the Fish 2, when the students transferred it to a 10˚C temperature of water, in just a few seconds its operculum movement stopped and the fish almost died.

conclusion
CONCLUSION

According to some information about the operculum movement of fish (R. Edmondson,United States 2006), cold water has more dissolved oxygen than that in warm water.

conclusion1
CONCLUSION

Therefore, the fish had to take more breaths in the warmer water to get much oxygen. Based on the results of the experiment, it was concluded that the rate of operculum movement of fish is higher in warm water and lower in cold water.

conclusion2
CONCLUSION

The students also found out that an increase in water temperature means a decrease in dissolved oxygen.

conclusion3
CONCLUSION

We all know that there are so many kinds of fish and they also have different characteristics, and so, the students came up with a conclusion that not all fish will have the same results as this if we try to conduct again an experiment about the operculum movement with a different species of fish.
