### Science exhibit

March8

My experience in science fair over all was good, I was in a fairly crowed room. I found that people found my project very interesting and were asking questions about the date collection. My highlight was when a parent took a lot of interest and asked me about the recipe of the sauce as well. My goal is to be more inviting to guest instead of shying away from them. I also wished that I included more graphs to show results. I want to make sure that I start testing from the start since I found myself running out of time.

### Science Lab Metal

February13

Introduction-
Heat capacity is the amount of heat an object can store. To find out if a material has a high heat capacity, you will have to see the slight change in temperature. Where as specific is when you the heat required to raise the temperature of the unit mass of a given substance by amount .measure this using a temperature device or a thermometer. A daily example would be when you stick a metal spoon in a hot soup the temperature of the spoon raises. Therefore making the spoon very uncomfortable to hold. Where as if you stick a wooden spoon then you will find the wooden spoon remains almost the same temperature.

Question: Do different materials have different thermal energy characteristics?
– Do different materials absorb or release heat in the same ways or rates?

3. Hypothesis: What do you think you will discover
I think that I will find the temperature of the water will rise because the metal cubes heat will transfer into the water.
4. Materials : metal cubes, stand ring, bun set burner, thermometer and tongs
5. Procedure- what steps, what setup, diagram or image of experimental setup
Step1) measure the desired amount of water in a beaker and place it on the ring stand.
Step2)The take another beaker and measure the desired amount of water .
Step3) adjust the Bunsen burner so it has a medium flame that has a blue tint.
Step4) place the first beaker on the stand then use the help of the tong to pick and place the metal cube in the water.
Step5) let the water reach a boiling point (100 Celsius ) measure the temperature
Step6) carefully take out the metal cube with the tongs and place it in the water.
6. Results- Data table, description of what you saw happen
7. Analysis
– Calculations- for one metal (the whole set).
– Data table of Cq
– Assumptions
– Explanation of meaning of results
– patterns that you see (Max, min)
So after looking at my chart I found that copper had a higher heat capacity than aluminum. I found that very surprising because I though that it would be the opposite. So something I also think would be a variable is the fact that the copper was let to boil for a little long the water was measured at 103 Celsius other than that i think my basic idea was correct but our results were off when we compared to other students.
8. Conclusion
– What was the important data that shows you that this is true.
– What errors (or problems) were there with your experiment that built inaccuracy into this experiment? This does not mean mistakes that were made… it means
problems
I found that different materials do have different heat capacities since in my experiment I used two different metals. I found that one of the metal attracted and released more heat than the other. I was happy to know that my hypothesis was right the metal did transfer the heat into the water causing a slight change in temperature. I was expected the temperature to raise with higher number but my notion was still accurate.

Question: Do different materials have different thermal properties? Does heat travel from warmer to colder places?

Hypothesis: Yes, different materials have different thermal properties and heat travels from warmer areas to colder areas. This was proven by my experiment since metal attracted and released heat into the water.
