Sixth-grade students conduct a laboratory experiment investigating the flow of thermal energy. They place a sealed plastic bag filled with water at 60°C into a beaker filled with an equal amount of water at 80°C. They then put the beaker with the plastic bag in an insulated container.

Based on the flow pattern of thermal energy, what can students predict will most likely happen in about an hour?



A. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in the beaker will be 60°C and the temperature of the water in the plastic bag will be 80°C.


B. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in the plastic bag will be 80°C and temperature of the water in the beaker will be 60°C.


C. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in both the plastic bag and the beaker will be 70°C.


D. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in both the beaker and the plastic bag will be 70°C.

Why would the climates of Austin, Texas and St. Paul, Minnesota be different?
(use the map)

a St. Paul is much warmer than Austin due to its closeness to the Great Lakes.
b St. Paul is at a higher latitude than Austin. The farther from the equator you are, the colder it is.
c The Altitude in Austin is much greater than in St. Paul, making Austin much colder
d The climates of both cities are very similar since they are almost lined up north and south of each other.

Energy and Temperature Activity Worksheet
Instructions: Follow the directions below to complete part one and part two of this activity. You will submit both parts once completed.



Note: You are not performing the experiment—only designing it.

Introduction
The purpose of this assignment is to design an experiment that another student could follow and use to test whether land or water heats faster.

You will complete the following:

Part One: Experimental Design. Plan out an experiment by answering the guiding questions below.
Part Two: Design a Lab Report. Write the outline of a lab report so that another student could complete the experiment by using the materials listed below:
sand
water
heat lamps
thermometers
cups

Part One: Experimental Design
In this section, you will think about what type of experiment to set up. Remember, you are NOT completing the experiment, only designing it. If you want to review the scientific method first, use this tutorial. Use these guiding questions to help you design the experiment. Answer each question below:

What hypothesis will the experiment test?
What are the variables?
What purpose would the sand serve?
What purpose would the water serve?
What purpose would the heat lamps serve?
What purpose would the thermometers use?
How can you use these materials to test whether land or water heats faster?
How would you compare whether land or water heats faster?
Within a 24-hour period, at what three points should the temperature be taken? Why?
What would an effective conclusion need to include?

Part Two: Design a Lab Report
Once you have designed the experiment, you must write out the instructions so another student could act as the experimenter and follow them. Fill in the following elements of this lab report as described in italics below.

Lab Report
Objective
Explain the purpose of your lab.


Procedure
List the experiment procedures. Some steps have been filled in for you. You may need to adjust the numbers to match the steps you decide on.

Identify the variables.
Write out your hypothesis in an if/then format.
Gather your materials.
Analyze the data.
Write your conclusion.

Data Analysis
Label a data table so that the experimenter can record observations for the sand and water temperatures at various points.


Conclusion
Explain what the experimenter should include in this section to show how the data proved the hypothesis.

The amount of water vapor in a given volume of air is ______________ .The amount of water vapor in the air at any one time depends on ______________ . Warmer air holds ______________ water thancooler air. Clouds form when humidity is ______________ and thetemperature is ______________ . ______________ humidity is definedas the amount of water vapor in the air ______________ by the amountthat would have to be present in the same air to form a ______________ or condense on a surface. ______________ is related to the humidityof the previous day. The air temperature at which water vapor in the air ______________ onto cool surfaces is the dew point.
