A solid sample that has a mass of 2.3 grams. The solid sample has a volume of 2.0 cm. What is the density of this sample?

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.

Measuring Physical Properties Lab Report
Instructions: In the Physical Properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in Tiny World. Record your observations and test measurements in the lab report below. You will submit your completed report.

Name and Title:
Include your name, instructor's name, date, and name of lab.


Objective(s):
In your own words, what was the purpose of this lab?


Hypothesis:
In this section, include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.


Procedure:
The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome.

Using the summary questions, clearly define the dependent and independent variables of the experiment.


Data:
Record the results of each of your physical property tests in the table below.

Wood Clay Brick Iron Aluminum Copper Nickel
Flexibility
(?/10)
Magnetism
(number of paper clips)
Thermal Conductivity
(W/(m·K))
Electrical Conductivity
(x107 S/m)
Density
(g/cm3)

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.

Using two to three sentences, summarize what you investigated and observed in this lab.
What building material did you use to build your house? Did your results support or fail to support your hypotheses?
What were the densities of the materials you chose for the walls and floor for the home in Tiny World? Why do you think a building material's density is important when building homes or architectural structures?
Why wouldn’t you choose wood or aluminum for the latches on your house?
Which material has the highest thermal conductivity? Which material has the highest electrical conductivity? Explain why thermal and electrical conductivity is so high with this material.
Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather. What building materials do you believe would work well to build a home in that area? Explain why you chose these materials.

Please answer the following essay question with 5-7 sentences.

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.
