While watching the video below, you may want to collect evidence (takes notes) in your ISN to be used later on the questions.

Throughout this lesson, you’ve learned about many different ways that humans contribute to greenhouse gas production. One way to understand these contributions is to break down the release of fossil fuels by economic sectors. Industry is one sector that can release greenhouse gases. The industrial sector also produces many different types of useful materials, including cement.

1

What is a fossil fuel?

A fossil fuel is any substance formed using renewable energy sources.

A fossil fuel is any substance with nuclear qualities

A fossil fuel is any substance that is man made.

A fossil fuel is any substance formed using non-renewable energy sources like coal, oil and natural gas.

1

What substances, when mixed together, make up cement?

water and powder

sand, pebbles and rocks

sand, rocks and water

a mixer, some powder and some water

1

Why is the process of making cement bad for our environment? Click all that apply.

Limestone heated uses fossil fuels

Burning Limestone emits CO2

A chemical reaction occurs, causing more CO2 to be emitted.

1

In Industry, what is the major source contributing to Global Climate Change?

The breakdown of limestone in cement

Machines

Power sources

Heating things up

1

Which source contributes the most CO2 into our atmosphere?

Limestone/cement production and usage

Ships

Airplanes

Long distance trucking

1

What would be the "game changer" for our climate when using cement?

Manufacture the cement using renewable sources

Stop using limestone and use alternative materials to make cement

Using alternative materials to build with

Use less cement per building

1

Check all the reasons why we choose to use limestone vs using alternative materials.

Too early in development

Too expensive

Not enough product to manufacture

Adopted tentatively, but not quite ready for production

Consider the following claim:

Cement production is a human activity that is a MAJOR factor affecting Earth’s mean surface temperature over the past century.

3

List 3 pieces of evidence you would use from the video, notes from your ISN or packet, and/or vocabulary words to prove or disprove the claim. Number each piece of evidence and use complete sentences.

5

Using the bar graph above, explain how the global production of cement might have a negative impact on the climate. Feel free to use evidence from the video you first watched as well. Write your answers in complete sentences.
