Goldfish

Background Information:
* Goldfish are exothermic, meaning their be temperature depends on the weewee surrounding them. As the water cools/heats the low things to be affected are their digestion, respiration, and immune response. When a gold fish is exposed to extreme cold water, their body starts to turn out down their non-vital organs first. They slow down their breathing because they put ont as much oxygen to bring to their working organs. As the water pop offs heated up, goldfish tend to bring to pass more active, and this is the time breeding is most correlated with.
conjecture:
* If you change the water temperature, then the amount of breaths the fish leave take will adjust, because the fish wont motive as much oxygen to perform its physical functions.
Experimental Design:
* Experimental/ Independent Variable Temperature of water
* Dependent Variable Amount of breaths taken by the fish
* take in First trial, Breaths taken: 89 Initial temperature: 25 ® C
Constants:
* The fish
* super acid mL Beaker
* Aquarium water
* Amount of time taken to drop off number of breaths
* Thermometer

Materials:
* Thermometer
* Goldfish
* 1000 mL Beaker
* Distilled water
* Ice
* Hot plate
* Timer
Procedure:
1.



weft 1000 mL Beaker half way with distilled water, and then track record the initial temperature of water.
2. Pick out a goldfish, and put it in the beaker. (Let it have a couple of minutes to settle into the brisk surrounding).
3. Record the amount of generation the fish opens its speak in a period of 60 seconds.
4. Insert thermometer into the beaker, easily add ice to the beaker until it reaches 3® C, recite the number of times the fish opens its mouth within a 60 second time period. Record data.
5. Place the beaker on the sultry plate and carefully raise the temperature to 6® C and count the breaths the fish takes, record the data.
6. Repeat step 5, raising the ground level by 3® each time until you...If you want to get a full essay, order it on our website: Ordercustompaper.com
