Sealing at Work

Aircraft assemblers use sealants at work.

Assemblers check the temperature to see how long the sealant needs to dry.

Assemblers can find this information on a line graph like this one.

The little circle º after the number means degrees.

Example: 120º F

The F means Fahrenheit.
It is important to add F after the degree sign.
If the temperature is in Centigrade, then use C instead of F.

Look at the line graph.

• If the temperature is 130º F, it takes the sealant 5 hours to dry.

Fill in the blanks.

1. If the temperature is 110º F, it takes the sealant to dry.
2. It takes the sealant 7.5 hours to dry if the temperature is .
   Did you remember to add the degree sign and the letter F?

Circle the correct word (less or more) to make the sentence true.

3. As the temperature gets lower, it takes more/less time for the sealant to dry.
