5. Construct a graph showing the average monthly temperatures in Hartford, CT.,
a city on the equator and a city in the Southern Hemisphere.
Questions:

1. What do you notice about the temperatures?
2. How is heat transferred throughout the Earth?

4. How is Steam used to create electricity in Power Plants?
A. Coal Plant: w​ ater is turned into steam which then is used to drive turbine generators
B. Natural Gas Plant:​ fuel produces heat, which heats up water to make steam which turns the
turbines
C. Nuclear Plant​:fuel produces heat, which heats up water to make steam which turns the
turbines
D. Where did Fossil Fuels originate? A​ ll were formed hundreds of millions of years ago before
the jurassic age
E. What is the difference between Renewable and NonRenewable forms of energy?
Renewable forms of energy are easy to renew, they are unlimited and you will never run out.
Nonrenewable forms of energy are not easy to renew, some take thousands of years to renew
while others never renew.

Part II - Water, Orange Juice and Vegetable Oil
1. Conduct an experiment to determine the Heat Gained by 20 g of each substance
2. You must measure the mass of Orange Juice and Vegetable Oil.
3. Research the Specific Heats of Orange Juice and Vegetable Oil in Calories/g C not in
Joules.
4. Make a data table
5. Construct a 3 Line graph for 2 minutes of data collection - 1 pt every 10 seconds
6. Write a conclusion about your results.

Critical Thinking Questions
1. What happens to the molecules in each of the beakers as heat is added?
The molecules become more separated because the heat is starting to break away the polar bonds
making the molecules more free to move.
2. Which substance showed the greatest temperature change? Least? Use data
3. Which substance does research say should show the greatest temperature increase?
Least? Why? How does this relate to Specific Heat?
4. How does Average Kinetic Energy relate to this experiment?
5. Why is water a great substance to put into a car engine radiator?

Practice Calculation
1. How much heat was gained by a 50 g sample of Orange Juice that increased its
temperature from 35 C to 75 C?

2. How much heat was gained by a 350 g sample of Vegetable oil that increased its
temperature from 24 C to 95 C?

6. Lab Experiment:
*Conduct an experiment that tests 3 different cups for their ability to insulate.
A. Conduct experiment
B. Create Data Table - Include Specific Heat
C. Write short conclusion paragraph that relates your data to research about the
effectiveness of the 3 materials to provide insulation.

Critical Thinking - Choose 2 out of 3 to research
Provide pictures
1. How did NASA protect the astronauts in their space vehicles from the harmful
radiation from space?
2. How is your home insulated? Research the “R” value system for insulation.
3. How does the atmosphere act as an insulator?

7. Lab Experiment: April 28-30
*Conduct an experiment to determine the Specific Heat of 3 different metals.
A. LAB TEMPLATE
