Key element • Carbon is the key element in many important processes: – Regulates the Earth’s temperature – Makes up the food that sustains us – Provides a source of energy to fuel human activities (transportation, factories, etc) – Used in photosynthesis in the form of CO 2

Where do you find carbon? • Most of the Earth’s carbon is stored in

Where do you find carbon? • Most of the Earth’s carbon is stored in rocks and sediments • The remaining carbon is located in the oceans, atmosphere and living organisms

Today’s lesson… • Today we will explore the carbon cycle. – What is the carbon cycle? – Why is the carbon cycle important to study? – How does a disruption of the carbon cycle impact the environment? • We will also explore recycling. – How does recycling impact the carbon cycle.

Definition: Carbon Cycle • The process of carbon continuously moving between living and non-living things on Earth and in the atmosphere • Carbon is mostly present as CO 2 • It can also be present as methane (CH 4)

Activity 1: Carbon Cycle Video • Directions: Watch the following video describing the carbon cycle. • Using both the video and the “Carbon Cycle Diagrams” respond to the questions in your guided notes. http: //studyjams. scholastic. com/studyjams/jam s/science/ecosystems/carbon-cycle. htm

Why is the carbon cycle important? • CO 2 is like an atmospheric blanket

Why is the carbon cycle important? • CO 2 is like an atmospheric blanket over the planet • Its job is to trap radiation from the sun (heat) to help keep the Earth’s temperature stable

Turn and Talk: What do you think? • What is the relationship between the Earth’s temperature and the amount of CO 2 present in the atmosphere? • As CO 2 increases…

Turn and Talk • As CO 2 increases, the temperature of the Earth increases

Turn and Talk • As CO 2 increases, the temperature of the Earth increases as well. • This increase in the Earth’s temperature can negatively impact the environment, which you will learn about tomorrow.

What can we do? • Looking back at the carbon cycle diagrams, brainstorm some

What can we do? • Looking back at the carbon cycle diagrams, brainstorm some actions that we can take as humans to not disrupt this cycle by releasing more CO 2 into the atmosphere.

Recycling • To recycle means to: – Convert (change) waste into reusable material –

Recycling • To recycle means to: – Convert (change) waste into reusable material – Use again • All waste that is not recycled ends up in a landfill – A place where waste is taken and dumped

Landfills • The waste is buried and covered over with soil • This method

Landfills • The waste is buried and covered over with soil • This method is used to make room for more waste • Consequence: The organic wastes present (food, paper, grass, etc) is digested by organisms living in the landfills • The digestion of this organic waste releases carbon in the form of methane gas into the atmosphere • Thus, more carbon is being released into the atmosphere unnaturally, disrupting the carbon cycle
