Topic 4 Lesson 2 Climate Change

Climate Change

Objective: I can describe ways in which climate can change.

Open Ended

List one thing you already know about climate change.

Open Ended

List one thing you want to learn about climate change.

Scientists collect weather data from different technology sources through the use of satellites and weather stations. They analyze the data to explain weather patterns.

Now it's time to Read on

Pg. 142

​Climate Change - is a change in temperature, precipitation (rain, sleet, snow), or other weather patterns over a long period of time.

Let's watch a video about Climate Change!

What do I need to do?

Lab Instructions

1. Look at the tree ring image on pg. 143

2. Determine the tree's age in years by counting the rings starting at the very center.

3. Next slide you will answer how old you think the tree is.

Multiple Choice

About how old is the tree on pg. 143?

• 10 years old

• 20 years old

• 16 years old

• 13 years old

Now....

1. Observe the width of the rings of the tree on page 143

2. Predict how you think temperature and precipitation affect tree growth. Remember to predict means to tell what you think will happen in the future. Write it in your book and be prepared to share.

3. Next, we will look at a website to further our understanding of tree rings and climate change.

List one thing you have learned today about climate change?

Greenhouse Effect

Describes how the atmosphere
traps energy from sunlight and
keeps Earth warm, similar to a
garden greenhouse.

Pg. 144-145

Greenhouse Gases

A gas that traps heat in the
atmosphere.

Open Ended

What is the greenhouse effect? What part of the visual provides evidence for your answer?

Open Ended

How might the path of solar energy change if greenhouse gas emissions decreased?

Open Ended

How does a greenhouse gas relate to the greenhouse effect?

Natural Factors and Climate Change

Climate Change - is a change in temperature, precipitation, or other weather
patterns over a long time.

pg.146

Multiple Select

What are two weather patterns that are affected by climate change?

• natural causes

• temperature

• precipitation

• volcanoes

Open Ended

Why is it important to collect climate data over time?

Humans and Climate Change

Let’s Read Pg. 147

Let’s Create a T-Chart and discuss evidence that explains how natural factors and
human factors contribute to climate change

Let’s complete an interactivity.
