LAB #4 – Heating Earth’s Surface

LAB #4 – Heating Earth’s Surface

copy the title

Sometimes, a plunge in a pool or lake on a hot summer day feels cool and refreshing. Why does the beach sand get so hot when the water remains cool? A few hours later, the water feels warmer than the land does.

Problem

What is the effect of radiant energy from a light bulb on the temperature of a tray filled with "soil/land" and a tray filled with "water/sea"?
↑

Copy the problem, make a hypothesis, use the writing prompts to guide you.

Hypothesis

If we add radiant energy from a light bulb to trays filled with "land" and "sea"....

then the temperatures of the trays will ______________________,
and this is because _______________________________________.

(What will happen to the temperature of the soil and water when the light is turned on? What will happen to the soil and water after the light has been turned off? Will they cool down evenly? Will they heat up the exact same? Will they heat up differently? Will there be a change in temperature? Why do I think this?)

Materials copy the materials

Soil
Water
Containers for soil and water
Overhead light
Thermometers

Stopwatch

Procedure

DO NOT COPY.. You don't DO this, I did it, watch the videos.

1. Add 300 ml of water to one of the boxes and 300 ml of soil to the other box.

2. Use a thermometer to find the temperature of the water and soil in each container. Record your data in the Results section.

3. Place the containers side by side underneath the overhead light. Be sure both containers receive the same amount of light.

4. Measure the temperature of the water in each container at 1-minute intervals for 10 minutes. Record your data in the Results.

5. After you record your 10 minute reading, turn off the light and take your initial reading with the light off.

6. Measure the temperature of the water and soil in each container at 1-minute intervals for 10 minutes. Record your data in the Results.

Results watch the videos, copy the data into these tables

	Temperature With Light On (°F)	Temperature With Light On (°F)		Temperature With Light Off (°F)	Temperature With Light Off (°F)
Time (min)	Soil	Water	Time (min)	Soil	Water
0			0
1			1
2			2
3			3
4			4
5			5
6			6
7			7
8			8
9			9
10			10

Analysis Answer these completely, make line graphs

1. Graph the data from the table using a line graph in degrees Celsius. Use one colored pencil to show data for the water container and a different one to show data for the soil container with the light on. Make a second graph with the light off. X-Axis: Time (min.), and Y-Axis: Temperature (°C). Draw lines to connect the temperature for each container.

2. Calculate the total change in temperature for each material. Do this by using the following formula:

Total Change = Final Temperature - Initial Temperature

3. Which material had the greater increase in temperature? Why do you think this is?

4. Infer from your graphs which cooled faster—the water or the soil. How could you prove this?

5. What was your independent variable? What was your dependent variable? What are three variables that should remain constant?

6. Relate: What is this modeling in the real world? (Hint: watch above videos)

https://www.wnct.com/news/sunday-science-tidbit-sea-breeze-and-land-breeze/

7a. Draw a picture of the lab setup with the light on. Label the following: lithosphere (land), hydrosphere (water), sun (light), convection arrow/heating up, convection arrow/cooling down, sea breeze.
7b. Draw a picture of the lab setup with the light off. Label the following: lithosphere (land), hydrosphere (water), convection arrow/heating up, convection arrow/cooling down, land breeze.

4. Cloud cover

5. Wind speed (mi/h or km/h)

B. Personal Paragraph

- How does this weather affect you?

How does it affect your clothing, outdoor activities, etc?

How does the weather affect what you eat or drink, what

you do, where you go, what you can or cannot do?

***5 Sentence Summary***

Self Expression

C. Illustration - Be creative, make an illustration of what the weather means to you today and how it affects your daily life. Illustrate your experience with the weather today. Use weather symbols, pictures, images, be creative! This should be ½ page.

Very Important Tips/Tricks/Hints

1. Have fun doing this! Learn something. Experiment. Explore.

2. What is your Independent Variable? Dependent Variable? Constants?
3. You must have proof that YOU did the research for your project. Have some type of visual evidence i.e. photographs, video clip.

Additional tips.....

Infer is based on observations in the present moment; this is why I think this happened. A prediction is future based; I think this will happen because I observe this now.
. Additional research explains your results, i.e. why did this happen? Use a search engine!
Use specific websites too! i.e. not just google.com, mrconsidinescience.blogspot.com, wikipedia.org, youtube.com, etc
This is not an ELA, but proper spelling, punctuation and grammar are expected in this class.
Test and retest to gather more evidence to support your data! A presentation deserving of an A+ will have 3 trials!
