Energy and Temperature Activity ,the am of this test is to figure out if land or water warms up more quickly in certain situations.
Energy and Temperature Activity
Part One: Experimental Design
1.Hypothesis:
We want to find out if land or water heats up faster when they both get the same heat.
2.Variables:
Independent Variable: The type of surface (land or water).
Dependent Variable: How much the temperature changes.
Controlled Variables: We keep the amounts of sand and water the same, and control how long and how strong the heat lamps are.
3,Purpose of Sand:
The sand acts like land in our experiment. It helps us see how fast it gets warm.
4,Purpose of Water:
Water is like a liquid surface. It helps us see how it warms up compared to land.
5.Purpose of Heat Lamps:
The heat lamps give a steady amount of heat to both the sand and water.
6.Purpose of Thermometers:
Thermometers measure and write down how warm the sand and water get during the test.
7.Testing Procedure:
Fill cups with the same amount of sand and water.
Put a thermometer in each cup to measure the starting temperature.
Use heat lamps on the cups for a set time.
Write down temperature changes regularly.
8.Comparison of Heating Rates:
We compare how fast the sand and water warm up to see which one is quicker.
9.Temperature Measurement Points (within 24 hours):
Start with the first temperature before adding heat.
Check the temperature regularly while heating.
10.End with the last temperature after the heat is done.
Effective Conclusion:
Sum up what we found. Say if land or water got warm faster. Also, talk about anything unexpected, mistakes, and what we can do better next time. Explain why this matters in real life, like understanding how different surfaces warm up.

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. Shape 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 Shape Part One: Experimental Design Use these guiding questions to create the experiment.
