You really need to read this:              

I'm not kidding. I walk you through answering every question on the lab report and I give away a lot of the answers here

Every year, students miss questions on lab reports even when the answers are right here in the walkthroughs. It's sad, really.

Unit 01 Lab Walkthrough:      

Many thanks to science teacher Edward Shapard for his guidance in helping students learn.  The science lab 'Walkthrough' is his idea, process and format.

Determine heating characteristics of soil and water.

Follow along below and I'll show you exactly what to do for this lab in a step-by-step fashion.  This lab takes approximately 25 minutes to complete. The lab will open in a new tab. So anytime you want to refer to the 'Walkthrough' you can click on that tab.

The purpose of a lab report is to share your scientific knowledge with others.  Lab reports must be written so that your peers can understand 1) what you did in your experiment, 2) what data you collected and 3) what conclusions you made, based on your data.  Write as if you are writing for someone who did not do the experiment.  You are sharing what you learned. 

What's in this walkthrough:

Setup

Determine heating characteristics of soil and water.

This virtual lab will allow you to determine the differences in heating and cooling between soil and water. 

 

 

When you actually do the lab:  Click on 'Virtual Lab'   Or click here to view the Virtual Lab Press 'Begin Lab'

Procedure

  1. Put both probes in at the same time.  The soil probe in soil and the water probe in the water. 

  2. Record your data in the data table on your Lab Report

  3. Record the starting temperature next to the '0' time, under the column label

    Wait about 1 minute until the temperatures do not change.  This will be your starting temperature for your Lab Report

    led: Temperature of Soil  (°C)   and  Temperature of Water (°C)

  4. Next turn on both lamps

  5. Click 'start' on the timer

  6. Record the temperatures of the soil and the water at 1 min

  7. Record the temperatures of the soil and the water at 3 min.

  8. Record the temperatures of the soil and the water at 5 min.

  9. Record the temperatures of the soil and the water at 10 minutes

back to top

After the 10 minute reading, turn off both lamps and 'reset' the timer

Now you are going to record the 'cooling' times.

  1. With the lamps off, press 'start' on the timer.

  2. Record the temperature of the soil and the water at 5 min

  3. Record the temperature of the soil and the water at 10 min.

 

You have now completed the lab data table (7 points).

Total  = 20 points

NOTE that the soil and water start out at the same temperature, room temperature.  When you turned on the light, energy like that from the sun heats the medium (either water or soil). 

Ask yourself, "Are they changing temperature at the same rate, or is one getting warmer than the other more quickly?   If so, which one?.

How to answer the questions

There's no mystery here. And there's nothing you have to figure out.  How to answer questions 1, 3 and 4 is found in the procedure section above.

It's a radical teaching philosophy, I know; but I believe that you shouldn't be graded on your answers to questions unless you've either been taught the answer, or shown how to figure the answer out. I guess I'm just weird that way..Score break-down

Understanding what's going on

You'll notice in the data that the soil and water heat up at different rates.

Answer Question #3 (5 points). Ask yourself, "Was your hypothesis correct?"  Write an answer in Question 3  Your hypothesis must be written in complete sentences.

Answer Question #4 (5 points).  Use complete sentences to express your thoughts.

Look at your data and consider the rate of temperature increase and decrease of water vs. soil.  Then consider living in areas that are coastal or by large lakes, vs. areas where you are land locked.  How would the temperature affect the weather?  Use complete sentences to express your thoughts.

How to improve your grade on this lab

Correct your lab and turn it back in for more points!

You get unlimited re-takes for labs if you're in my class (Mrs. Lilly). Just read the comments I give you when I turn back your lab (see section above) to figure out what wasn't right about the lab, fix it in your lab report, and turn the new report back in to me. If you're in another teacher's class, ask them about their retake policy for labs.

You can keep doing this until you get a perfect score, but near end of the semester, we stop accepting labs, so don't wait until the last minute!
