Celsius or Fahrenheit Advanced teaches students the difference between these two measurements of temperature. Students will discover where the two names come from and how to convert one to the other and vice versa.

You can check out the “Options for Lesson” section of the classroom procedure page for additional suggestions for ideas and activities to incorporate into the lesson. One option is to teach this lesson simultaneously with others about mathematical formulas. You could also fill cups with water at different temperatures and have students use thermometers to find measure the temperatures.

# What our Celsius or Fahrenheit Advanced lesson plan includes

Lesson Objectives and Overview: Celsius or Fahrenheit Advanced teaches students the difference between these two units of measurements. Students will also learn how to convert from one to the other. This lesson is for students in 5th grade and 6th grade.

### Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. This lesson requires paper, pencils or other writing utensils, and calculators.

#### Options for Lesson

In the “Options for Lesson” section of the classroom procedure page, you will see some suggestions for additional activities or ideas to add to the lesson if you want to. For a hands-on approach, have students measure the temperature of different cups of water and calculate the other temperature. Or, each day, have students use the formula to convert Fahrenheit to Celsius of the current temperature locally, in another state, and another country. Next, use the temperature on the weekly weather temperature predictions online or in a newspaper to convert between the two. Finally, blend this lesson with lessons focusing on mathematical formulas. Take out your phone and show students how many weather apps will convert from one system to another for you easily. You can also show them how to ask Siri!

### Teacher Notes

The teacher notes page provides an extra paragraph of information to help guide the lesson. You can use the blank lines to write down any other ideas or thoughts you have about the topic as you prepare.

## CELSIUS OR FAHRENHEIT ADVANCED LESSON PLAN CONTENT PAGES

### Two Types of Degrees

The Celsius or Fahrenheit Advanced lesson plan contains two content pages. Fahrenheit was invented by a German-Dutch physicist named Daniel Gabriel Fahrenheit in 1724. He created the scale with the freezing point of water at 32°F and the boiling point at 212°F. The distance between the freezing point and boiling point is 180 degrees apart. Fahrenheit is written with a small superscript circle (°) for degrees and the capital letter F.

Celsius, also called centigrade, was invented by the Swedish astronomer Anders Celsius in 1742. Water freezes at 0°C, and it boils at 100°C. This scale is called centigrade because there are 100 (cent-) degrees between freezing and boiling. Degrees Celsius is written with a small superscript circle (°) for degrees and the capital letter C.

### Celsius vs. Fahrenheit Worldwide

Celsius is the most common temperature scale in the world. Every country, except for five, uses it to measure their temperatures. Obviously, the United States is one of those five countries. The other four countries are Belize, Palau, the Cayman Islands, and the Bahamas.

Celsius is part of the International System of Units (SI), often referred to as the metric system. We use the metric system in science class when we work with centimeters, kilograms, and milliliters. But it isn’t just used in science class. The entire scientific world uses the metric system. However, Fahrenheit is part of the Imperial system, not the scientific world.

### Conversion Process

So how do we convert from degrees Celsius to degrees Fahrenheit and vice versa? We can often use our phone to quickly convert from one system to the other. Most weather apps will actually let you choose which method you want to see. But before computers, phones, and apps made it easy, people had to use a mathematical formula to convert one system into another.

To convert temperatures in Fahrenheit to degrees Celsius, subtract 32, then multiply by 5 and divide by 9. The lesson provides an example equation that requires students to convert 85°F into Celsius. To convert temperatures in Celsius to degrees Fahrenheit, multiply by 9, divide by 5, and add 32. Again, the lesson offers an example equation that requires students to convert 7°C into Fahrenheit.

## CELSIUS OR FAHRENHEIT ADVANCED LESSON PLAN WORKSHEETS

The Celsius or Fahrenheit Advanced lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each one will help students solidify their grasp of the material they learned throughout the lesson. You can refer to the classroom procedure guidelines to know when to hand out each worksheet.

### WHAT’S THE TEMP ACTIVITY WORKSHEET

For the activity, students will cut apart the squares on the first worksheet. Each set (total of five) shows a picture and the temperature in Celsius and Fahrenheit. Students will paste the pictures on a separate sheet of paper and match each image the two temperatures the scene represents.

### CONVERTING TEMPERATURES PRACTICE WORKSHEET

The practice worksheet requires students to convert temperatures from degrees Fahrenheit to Celsius and vice versa. The worksheet provides the formula students should follow to complete each calculation. It also provides items that match those temperatures.

### CELSIUS OR FAHRENHEIT ADVANCED HOMEWORK ASSIGNMENT

Similar to the practice worksheet, students will convert temperatures that correspond to various states in the United States.
