Cautiously take the goldfish out of its container and set it in the Ziploc bag that is filled
1/3 of the original water the fish was in.
2. Then put the Ziploc bag in a beaker that is 1/3 filled with room temperature water (21°C or 70°F)
3. Allow the goldfish to adapt to the temperature for one minute
4. Place a thermometer into the Ziploc bag and record the number of times the goldsifh opens and closes its mouth in a period of one minute onto your data table
5. Record the number of times the goldfish opens and closes its mouth
6. Take the Ziploc bag out of the beaker and add the crushed ice little by little to decrease the temperature 12 degrees below the room temperature
7. Put the bag into the beaker again and check the temperature with

Millions of people come from across the world to visit Seaworld every day without thinking about the lives of the animals behind the scenes. Why would they have concerns? From Seaworld’s commercials to the website, they convince the general public that Seaworld is the place to go to see the happy sea animals perform. If Seaworld is such an ecstatic place, what excuse does Tilikum, their greatest well known orca whale, have for the three attacks on trainers? The documentary “Blackfish” was created by the director Gabriela Cowperthwaite because she questioned herself after realizing Tilikum's odd behavior over time in captivity, and if there was any indisputable parts to animal captivity?
4Slowly add more water to the blue glass until you can see a bulge of
Cowperthwaite begins Blackfish by discussing the biggest accident SeaWorld is known for. The audience is introduced to a chilling 911 phone call regarding one of the whales and the trainers. It appeals to shock factor by stating “a whale ate one of the trainers” (Blackfish, 2013), this phrase is repeated a second time which adds emphasis to the context of the film. In contradiction
one gram of water by 1ºC. I chose to use water because it is safe,
The materials necessary for this experiment are: four plastic cups numbered 1-4, a scale, six ice cubes, cold deionized water, a pipet, a heat lamp, two LabQuests, four temperature sensors, some paper towels, and four partners in total. The first thing you will need to do is use the tare function to zero out the mass of cup #1, then add three ice cubes to the cup. Record the mass of the ice cubes. Once the mass is recorded, add cold deionized water to the cup until the total mass is between 99.80 g and 100.20 g. Use the pipet to add and subtract water as needed. Put cup #1 aside when this is accomplished. Repeat this process for cup #2. Continuing to cup #3, use the tare function to zero out the mass of the cup and then add between 99.80
Measure and record the temperature of the water in the Styrofoam cup. Leave cardboard cover on until the heated metal is ready to be transferred into the calorimeter.
Then, repeat steps 7-11 another 4 times but with the room temperature water. For the room temperature water just leave it in the room but try not to change the room’s temperature. 15. Try to put all your recorded data into a table for organization 16. Repeat the entire experiment for more reliable data.
5.) One at a time, place your test tubes in the water bath and heat the first test tube to 25 , the second to 50 , the third to 75, and the last to 100 degrees c. Remeber to stir with your stirring rod every so often.
- Temperature was measured after and exact time i.e. 1 minute, 2 minutes, 3 minutes.
In the experiment we have a time taker, tapper, and 3 observers. The tank should have a black line straight down the middle of it, however, if the 10 gallon tank does not already have a line down the central part of the tank, take a sharpie and draw one exactly down the middle. Once you acquire the tank make sure there are 8 fish in the tank, if not, position 8 fish in the tank. The first trial that was done required the tapper and the time taker with 3 observers. The tapping began for 10 seconds while the fish behavior was observed by the 3 of us observers. After the 10 seconds the results were verified and discussed among the observers. There was an elimination period for 1 minute, and trial 1 was repeated again for the second time making it trail 2 for 20 seconds. The results were documented once again and discussed. The second trail that was done required a little more focus to assure the tapping and placement was the same as the one before. After 20 seconds the results were recorded. There was a rest period for 1 minutes, and trial 2 was repeated making it trial 3 for 30 seconds. The results were
In order to determine the mass of salt required for the ice pack to reach 0.0°C and hot pack to reach 65°C, we must set the ΔHdissolution which will be calculated from our trial equal to the ΔHdissolution of hot/cold pack containing 100 mL of water and reaching a temperature of 65°C/0.0°C. This equation is given below:
Methodology: A plastic cup was filled half way with crushed ice and mixed with four spoonfuls of 5 mL of sodium chloride. A thermometer was quickly placed inside the cup to take the temperature and the
