1. What’s the Accuracy of Various Thermometers? By Fabian Fernandez Mr. Hankins 1 st period

2. Problem Statement: What's the accuracy of different types of thermometers in different temperatures at 76(° F), 75(°F), 74(°F) ? What's the accuracy of different types of thermometers in different temperatures at 76(° F), 75(°F), 74(°F) ?

3. Research Paper: The Thermometer was invented during the 16th and 17th century. the name came from the Greek word thermos meaning warm and meter to measure. A thermometer has two important things the temperature sensor bulb on a mercury thermometer in which some change occurs with temperature, plus converting this physical change into a value the scale on a mercury thermometer. Finally in 1724 Daniel Gabriel Fahrenheit produced a temperature scale which now is named after him. I learned that mercury is the most accurate out of all thermometers which where alcohol and kerosene. I learned that mercury is the most accurate out of all thermometers which where alcohol and kerosene. I also learned that mercury is the most commonly used thermometer its used for when people are sick too. I also learned that mercury is the most commonly used thermometer its used for when people are sick too.

4. Hypothesis: If the temperature is set to 76(°F), 75(°F), 74(°F). Then I hypothesize that The Kerosene thermometer will be most accurate.

5. Variables: Independent variable: Independent variable: - Type of thermometer Dependant variable: Dependant variable: -The temperatures recorded by the thermometers

6. Controlled Variables: Amount of temperature Amount of temperature How many thermometers How many thermometers The brand thermometer The brand thermometer Time of the day experimented on Time of the day experimented on The size of thermometer The size of thermometer

7. Data:

8. Conclusion Mercury turned out to be the most accurate out of all the other thermometers because it had the closest results compared to the other types of thermometers which where alcohol and kerosene. So my hypothesis was proved wrong. Mercury turned out to be the most accurate out of all the other thermometers because it had the closest results compared to the other types of thermometers which where alcohol and kerosene. So my hypothesis was proved wrong.

9. Mercury was the most accurate cause it was closest to 76.2 which was the average Graph:

10. Experiment #2 Problem Statement: what's the accuracy of different types of thermometers in water with ice in it ? Problem Statement: what's the accuracy of different types of thermometers in water with ice in it ?

11. Hypothesis Hypothesis: If the water has ice in it then I predict that the kerosene thermometer will be most accurate. Hypothesis: If the water has ice in it then I predict that the kerosene thermometer will be most accurate.

12. Variables Independent – type of thermometer Independent – type of thermometer Dependant – how cold the water is Dependant – how cold the water is

13. Controlled Variables Time of day experimented on Time of day experimented on How many thermometers How many thermometers Brand thermometers Brand thermometers Amount of ice Amount of ice Size of thermometer Size of thermometer

15. Conclusion Kerosene turned out to be the most accurate out of all thermometers which where alcohol and mercury. It was most accurate cause it was the closest of all so my hypothesis was proved correct. Kerosene turned out to be the most accurate out of all thermometers which where alcohol and mercury. It was most accurate cause it was the closest of all so my hypothesis was proved correct.

16. GRAPH GRAPH Kerosene was the most accurate because it was closest to 34.6 which was the average

17. Problem statement: what's the accuracy of different types of thermometers in a freezer at low, medium, high. Experiment #3

18. If the freezer is set at low, medium,and high then the kerosene thermometer will be most accurate. Hypothesis

22. Conclusion Alcohol turned out to be the most accurate out of all the thermometers which where kerosene and mercury. Alcohol was the most accurate cause it was the closest of all the other thermometers. So my hypothesis was proved wrong. Alcohol turned out to be the most accurate out of all the thermometers which where kerosene and mercury. Alcohol was the most accurate cause it was the closest of all the other thermometers. So my hypothesis was proved wrong.

23. GRAPH GRAPH Alcohol was the most accurate because it was the closest to 27.6 which was the average.
