Mr. Larsen's video tutorial guides students through the process of working with isobars on a map. It begins with an introduction and instructions, followed by an explanation of isobars and how they differ from isotherms. The video then details how to calculate pressure from station models and draw isobars on a map. Students learn to place isobars between pressure points, connect them, and label them correctly. The tutorial concludes with finding and drawing additional isobars, ensuring students understand the entire process.

What should you do before starting the worksheet according to Mr. Larsen?

• Ask a friend for help

• Complete the worksheet

• Read the instructions

• Watch the entire video

What do isobars represent on a map?

• Temperature

• Wind speed

• Humidity

• Pressure

How do you adjust the number 126 to find the pressure?

• Subtract 10

• Move the decimal and add a 10 in front

• Multiply by 2

• Add a 5 in front

What is the first step in drawing isobars on a map?

• Use a ruler

• Mark the points with X

• Draw random lines

• Start at the bottom

Where should you place the isobar line for a pressure of 1004?

• Next to 1012

• Between 1002.4 and 1004.4

• Above 1009.7

• Below 1008.4

What should you do after marking the points for 1004?
