When we want to know how long something is, we use a ruler. But when we want to know how hot or cold it is, we use a special tool called a thermometer. Temperature tells us if something is warm or chilly, and we measure it in degrees Fahrenheit (°F) or degrees Celsius (°C).
Imagine you have two thermometers. One shows degrees Fahrenheit, and the red line is at 65°F. The other shows degrees Celsius, and the red line is at 15°C. The red line on a thermometer tells us the temperature. If the red line is tall, it means it’s warm or hot. If the red line is short, it means it’s cold.
When it’s hot outside, we can have fun by going swimming, visiting the beach, and wearing shorts and t-shirts. But when it’s cold, we can play in the snow, stay cozy indoors, and wear warm clothes like long pants and coats.
Let’s look at two thermometers with tall red lines. The temperature is about 90°F on the Fahrenheit thermometer and 32°C on the Celsius thermometer. On a day like this, I would love to go swimming and wear my bathing suit.
Now, let’s check out two thermometers with short red lines. The temperature is about 25°F on the Fahrenheit thermometer and about -5°C on the Celsius thermometer. On a chilly day like this, I would enjoy sled riding, building a snowman, and having a snowball fight. I would wear snow pants, a sweatshirt, and a winter coat to stay warm.
Temperature helps us decide what fun activities we can do and what clothes to wear. Isn’t it cool to know how to read a thermometer and plan your day?
Thermometer Craft: Create your own paper thermometer! Use a strip of paper and draw a thermometer with a red line that you can move up and down. Practice setting the red line to different temperatures and discuss what activities you might do at each temperature. For example, if the red line is high, what summer activities would you enjoy? If it’s low, what winter activities would you choose?
Temperature Scavenger Hunt: Go on a scavenger hunt around your home or classroom to find items that are hot, warm, or cold. Use your sense of touch to feel the temperature of different objects like a cup of warm water, a cold ice cube, or a cozy blanket. Discuss how each item feels and why it might be that temperature.
Weather Diary: Keep a weather diary for a week. Each day, draw a picture of the weather and write down the temperature. Use a real thermometer if you have one, or check the weather online with an adult’s help. Note what clothes you wore and what activities you did. At the end of the week, look back and see how the temperature changed and how it affected your choices.

When measuring length, we use a ruler. To find the temperature, we look at a thermometer. Temperature indicates how hot or cold something is, and we measure it in degrees Fahrenheit (°F) or degrees Celsius (°C).
Here are two thermometers: one shows degrees Fahrenheit, with the red indicator at the 65°F mark, and the other uses degrees Celsius, with the red indicator at the 15°C mark. The amount of red you see on a thermometer indicates the temperature outside. A tall red line means the temperature is warm or hot, while a short red line indicates it is cold.
When the temperature is hot, we can go swimming, visit the beach, and wear shorts and short-sleeved shirts. Conversely, when the temperature is cold, we can play in the snow, stay indoors, and wear long pants and coats.
Looking at these two thermometers with tall red lines, the temperature is about 90°F on the Fahrenheit thermometer and 32°C on the Celsius thermometer. In this temperature, I would go swimming and wear my bathing suit.
Now, examining these two thermometers with short red lines, the temperature is about 25°F on the Fahrenheit thermometer and about -5°C on the Celsius thermometer. In this temperature, I would go sled riding, build a snowman, and have a snowball fight. I would wear snow pants, a sweatshirt, and a winter coat.
