TIP @ Columbia - A Hot Hand! (temperature introduction)

Short description: [one or two sentences only] Students will be introduced to both the Fahrenheit and Celsius temperature systems. Then, students will apply temperature to their daily lives and measure the temperature of the palm of their hand using the temperature probes.

Duration of lesson(s): 90 minutes

Grade level(s) and/or target group(s): 5th/6th grade

Subject(s): Science

Technologies used: computer, Vernier computer interface, LoggerPro, temperature probe

[Adapt the following to fit your lesson]

Objectives: Students will be able to...

1. 1. Accurately read a thermometer to determine metric measurement

2. To understand the Celsius system and apply them to everyday scenarios

3. To understand questions/hypothesis of the scientific method and apply it to a short temperature lab

4. Use a computer to measure temperature and compare results

Key Questions/Driving Questions: What is temperature and what are applications in our daily life?

Prerequisites and Sequence of Lessons in Unit: Prior to this lesson, students were introduced to the metric system and learned the following lessons in the measurement unit:

1. metric length- using a centimeter/millimeter ruler for measurements

2. metric volume- direct measure, capacity, irregular volume through displacement

3. metric conversion (between units)

4. reading a graduated cylinder

5. reading triple beam balances and understanding metric mass

6. estimating and measuring actual metric measurements

Lesson Introduction: What is the temperature like outside today?

Where does the red stuff inside the thermometer like to go when it is summer? Winter? Fall/Spring?

What is the "red stuff" inside of a thermometer?

a. What does it mean when the thermometer goes up high?

b. What does it mean when the thermometer goes down really low?

c. If I wore a hat, scarf, boots, a heavy coat, a pair of paints, and gloves, what do you think the thermometer would look like? What season would it be?

d. If I put the thermometer way up here, what kind of cloths would I wear?

e. If I put the thermometer right here (at 60 degrees), what season do you think it is? What would you wear?

Color your thermometers so that each one would read an appropriate temperature for each one of the four seasons. Then paste them in the correct box. Finally, you may color in the rest of the picture.

Lesson Core:

Celsius temperature readings are part of the metric system. The system is generally scaled between 0 and 100 degrees. O degrees is freezing, 100 degrees is boiling and around 25 degrees is room temperature.

"Zero's ice!

23 is nice!

100's like boiling rice!"

Now, I have pre-made 10 different flashcards for you with different temperatures on them for each group. Each group will also get a person and different clothes to dress them up in or dress them down in. So, for example, if the first flashcard you pick up is 45 degrees Celsius, we know that it means its going to be real hot outside. What kinds of clothes do you wear when its real hot outside? Put those clothes on the person and draw them on your class work sheet on the person as well. We will review them as a group as soon as you have completed all of them.

So, as part of our lab today, we are going to first talk about the scientific method. The scientific method is a set of steps that scientists go through when they complete investigations and experiments. There are five steps total:

1. Question

2. Hypothesis

3. Materials/Procedure

4. Results

5. Conclusion

Today, we are going to focus on the first two parts of the scientific method. Before scientists can experiment or carry out any types of investigations, they first have to create or develop some time of question. What kinds of questions are good ones? Questions that can be tested, questions that do not have "yes" or "no" answers, questions that are practical with the materials we have in the classroom.

Our question for today's class is: How is the temperature of water affected when high temperatures are mixed with low temperatures?

Hypothesis: a hypothesis is an educated guess, a guess that we make that has to answer our question.

So, if someone asked you the question, how would you answer? What are some thoughts that may come to your thoughts immediately? (ex. answers)

warm water, it will stay hot, it will stay cold, depending on the two temperatures, it will be warmer or colder

How do we write a hypothesis? For sixth grade, we are going to focus on writing it with a specific format or design that will help us write it the same way every time. As you get into higher grades, you most likely will change the way you write the hypothesis. The format we will use is, "If..............., then..........."

If we mix higher temperature water with lower temperature water, then ____________________________________________________.

The lab is quite simple, but it will help us to read thermometers and temperature probes. Today, we have Mr. Brant with us to talk to us about how to use the temperature probes.

First you are going to get hot water, in a plastic cup. As soon as you get it, leave the temperature probe in the water for 1 minute before you take the reading. Record the reading on your paper. Secondly, you'll get a cup of cold water. As soon as you get it, take the temperature and leave the probe in the water for a minute before recording it on your lab sheet. Lastly, mix the hot water and cold water in an empty cup and immediately insert your temperature probe to take the reading of the water. Take a look at the numbers and see if you your hypothesis is true or false.

Now that you are familiar with how to use Celcius thermometers, let's let Mr. Brant introduce us to the temperature probes. In this experiment you will measure the temperature of the palm of your hand and the palm temperatures of your teammates. In the process, you will get to know the computer program Logger Pro and how to use Temperature Probes. You will also get to know your teammates better. In this experiment, you will use a computer to measure temperature, calculate temperature averages and compare results.

Make sure you follow directions and complete the data chart below.

Lesson Closure:

Was your hypothesis correct or incorrect? Why?
Why do you think the temperature of the third cup was what it was?
How do you think the temperature of third cup would change if the hot water was 10 degrees Celsius hotter?
How do you think the temperature of the third cup would change if the cold water was 10 degrees Celsius colder?
