Activity #1

1. Does hot water or cold water freeze faster? Cold
2. Does hot water or cold water boil faster? Hot water
3. Does salt water freeze faster or slower than regular water? Slower

Questions/Items to then include in you blog posting for this activity:
1. Pictures of your experimental materials and setup.

2. Your hypothesis to the questions posed. I predicted that the cold water was going to freeze faster than the hot water because the temperature is closer to the freezing point. For the next question, I predicted that the hot water would boil faster than the cold water because since it is already at a hotter temperature, it wouldn't take much longer for it to get to a boil. For the last question, I predicted  that salt water would freeze slower than regular water because there is less particles and substances in it, making it harder for the process to happen since other particles are inside the water.
3. Data in the form of a graph or table

Freeze Time	Cold water (1 tsp)	Warm water (1 tsp)
Test 1	6 min 23 sec	12 min 33 sec
Test 2	7 min 1 sec	13 min 12 sec

Boil time (on high)	Cold water (one cup)	Warm water (one cup)
Test 1	2 min 14 sec	2 min 10 sec
Test 2	2 min 58 sec	1 min 54 sec

Salt water V.S regular water	water (one cup) with 1 tsp salt	Regular water (one cup)
Test 1	58 min	10 min 15 sec
Test 2	1 hr 2 min	11 min 22 sec

4. Show data of experiment repeated (see above)
5. List your controlled variables for your experiment The heat temperature of the burner, the pan, the amount of water used, the temperature of the water (how hot or how cold the water really was), the temperature of the freezer
6. Formulate a theory that answers the questions posed.Through these experiments I have found that hot water will boil faster that cold water because it is closer to the boiling point. Cold water will freeze faster than hot water because it is closer to the freezing point. And lastly, regular water will freeze faster than salt water because the salt prevents the water from freezing as easily because of the particles distilled in the water.
7. Image of the atoms that make up water molecules.

8. Video or animation that shows how water molecules are arranged in the three states of matter for water.

9. Describe the scientific method/process and how each step correlates to your own experiments.

Ask a question: In each process, a question was asked that needed to be experimented with to find conclusions. So you ask a question about what you have observed. For example, does hot or cold water boil faster? 

Do background research: Instead of starting from nothing, it is important to use different sources and other research so that you may get a better idea of what you are looking for and have a well thought out hypothesis before constructing it. This will also help to avoid repeating past mistakes in experiments.

Construct a Hypothesis: A hypothesis is to be formed in order to base the experiment off of. That being said, once the hypothesis is created, the experiment tests the hypothesis. For example, I predicted that hot water would boil faster than cold water  but there was no evidence that I was right, therefore, an experiment needed to be done to find proof. For example, If hot and cold water are boiled, then hot water would boil faster.
Test Hypothesis: This is where you test to see if your hypothesis is correct. You do this by getting data from the experiments and trying to keep the general experiment the same while changing one factor at a time to come to a conclusion. For example, when doing the experiment to see what boils faster, it is important to time the experiment and make sure there are the same amounts of water in each one and that they are at the same temperatures.
Analyze Data: Once the experiment is completed, you will be able to see whether or not your hypothesis is correct by taking the data from the experiment. For example, I timed how long it took for both the hot and cold water to boil.
Draw Conclusions:After you analyze the data, you will be able to draw conclusions from your experiment to see if the hypothesis you created was true or false, this will let you know whether or not you need to start this scientific method process over again.
Share Results: Once a conclusion has been formed, it is important to share the information you have found with others. For example, I found that hot water boils faster than cold water.
