Title of Investigation:Calm Water
Names:Holly and Lucy
Date:Semester 2 2014
1. In this investigation, we are trying to find out: what temperature of water makes people the calmest.
2. What we think will happen is:wethink luke warm water will make people the calmest.
3. Why we think this will happen is:luke warm water is the same temperature as air so only the texture is different. It’s also the same temperature as your body.
4. In this experiment, we will change one thing only and record what happens.
The one thing I will change is:the temperature of the water.
5. (A) the thing that I will record is: which temperature makes people the calmest. We will be able to see if there the calmest by seeing the look on their face and asking them how they feel and there reaction.
(B) We will make measurements using: a thermometer.
6. The things which will be kept the same throughout the experiment (because
they would change the result if they were allowed to change) are: the amount of water, place we do the testing, the time we do the testing.
7. We will do my investigation by: we will record the temperatureofthe water. Then we will ask students to place their hand near and if they can into the water.
8. The safety precautions that we need to take are: not to make water too hot, and we will warn students to take care.
9. What happened?
We found that the favourite temperature overall was 30 degrees.
Then it was 0 degrees. Then it was 50 degrees. Then it was15 degrees. Then it was 70 degrees. See table below for all results.
10. Is this what we thought would happen?
15 degrees is what we thought was going to be the favourite so we were not right.
11. Why do you think this happened?Because 30 degrees isn’t cold and it isn’t hot.
12. What did you find difficult when doing this experiments. Getting the water to the right temperature.
``
13. If you were to do this experiment again what would you change to make it
better? Have different temperatures of the water.
