Lesson 5: Convection Currents in the Air Lesson 5 Investigating the Effects of Colliding Air Masses

Lesson 5: Convection Currents in the Air Big Questions: What happens when cold moist air meets cold moist air? What happens when hot moist air meets hot moist air? What happens when cold moist air meets hot dry air? Hypothesis: Use your chart to form your hypotheses.

Procedure What are some ways we could set up two Convection tubes to show two different types of air colliding? Using this setup of the convection tubes and the materials listed on the board, how can we test our Big Questions?

Collecting Data ADD MOIST AND DRY TO BOTH YOUR CHARTS Setup of Convection Tubes Observations (What Happened to the Air) Cold Moist & Cold Moist Warm Moist & Warm Moist Hot Dry & Cold Moist

Lesson 5 -Investigating the Effects of Colliding Air Masses Day 2 – Analyzing Our Data

Worksheet 5.1b - Convection on the Earth Using the diagram on page 66 – Draw a punk stick, smoke and arrows on the Convention Tubes to show the movement of air. In the space below, explain why the air moves like this.

Worksheet 5.1b Convection on Earth Answer these in the space below the illustrations. 4. Use the results of your experiments to explain what is happening in the pictures.

Worksheet 5.1b Convection on Earth Answer these in the space below the illustration. 5. Based on our experiments, how can you explain why so many more tornadoes happen in Tornado Alley than any other part of the world?

Air Mass Reflection 1. What did you observe when both tubes contained air with the same temperature and humidity conditions? Why do you think this happened? 2. What did you observe when the tubes contained air with different temperature and humidity conditions? Why do you think this happened? 3. Under what conditions do you think wind and rotating storms might form?

Lesson 5 -Investigating the Effects of Colliding Air Masses Day 3 – Literature Connections

Read the articles “Why Does the Wind Blow?” And “Trouble in Tornado Alley”

Weather Fronts Read "Weather Fronts“ on page When do weather fronts occur? 2. What are the four types of weather fronts and when do they occur? 3. In your notebook, draw and label an example of each front type.
