The air flow patterns that circulate throughout Earth’s atmosphere are an integral
component of weather and subsequently climate. This chapter describes these
patterns. Focused on climate variability and human induced climate change, this
chapter provides an essential background for the next few chapters.

Activities and Labs:
Weather and Climate Activity Worksheet due Tuesday
Student:_________________________________________________
Materials:
Three waterproof containers, three thermometers, a heat lamp and ring stand,
light sand, dark colored sand, and water.
Procedure:
1. Fill the three containers with the light sand, the dark sand, and the water,
respectively to the same height.
2. Take the initial temperature of each of the materials.
3. Turn on the heat lamp and place it so that it equally distributes heat to each of
the containers.
4. Take the temperature of each of the materials every 5 minutes for 25 minutes.
5. Now, turn the heat lamp off and continue taking the temperature of each of
the materials as they cool for the next 15 minutes.
6. Record your data in the table below:
LAMP ON: LAMP OFF:

Conclusions:
1. Which of the three materials heated the fastest? Why?
2. Which of the three materials cooled the fastest? Why?
3. What can you conclude from these results?
4. What do these tell you about the heating and cooling of Earth? Think in terms
of the amount of land vs. water on our planet.
5. How would these results affect the weather on Earth?
Lichens activity due Thurs
This is a very simple activity that blends concepts learned from earlier in the year
with ones in this current chapter. The presence of lichens on
trees indicates good air quality. If you have access to the outdoors, take the
students out and look for lichens. They grow as crusty looking growths on trees.
If you don’t have access to outdoors, then use the internet to look at lichens.
After looking at lichens, give an assignment to the students to research lichens
found in their area. They are more than an important pioneer species and
abound in various types.
