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. 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?

can someone help me with part one please ☆ ～('▽^人) you'll receive 100 points

Answer 1

To test whether land or water heats faster, you can design an experiment using sand, water, heat lamps, and thermometers. By comparing the rate at which the sand and water cool off, you can determine which material heats faster.

Step-by-step explanation:

To test whether land or water heats faster, you can design an experiment using sand, water, heat lamps, and thermometers. Here is a step-by-step plan for the experiment:

1. Place equal masses of dry sand and water at the same temperature into two small jars.
2. Heat both substances for the same amount of time.
3. Record the final temperatures of the two masses.
4. Now bring both jars to the same temperature by heating for a longer period of time.
5. Remove the jars from the heat source and measure their temperature every 5 minutes for about 30 minutes.

By comparing the rate at which the sand and water cool off, you can determine which material heats faster. An effective conclusion would include a statement about which material heated faster based on the observed data and a discussion of the possible reasons for the observed results.
