Drawing Isobars and Pressure Representation

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?

• Erase the marks

• Connect the X's with a line

• Add more X's

• Start over

What is the next step after drawing the 1004 isobar?

• Draw the 1008 isobar

• Erase the 1004 isobar

• Finish the worksheet

• Draw the 1016 isobar

How do you determine the placement of the 1008 isobar?

• Find it between 1004 and 1009

• Place it randomly

• Draw it next to 1012

• Use a calculator

What should you remember to do with each number when drawing isobars?

• Multiply by 3

• Add a 10 in front and a decimal point

• Subtract 10

• Add a 5 in front

What should you do if you have questions while working on the worksheet?

• Ignore them

• Ask Mr. Larsen
