Elements cycle through our environments such as oxygen, carbon or nitrogen
The Nitrogen Cycle https://www.youtube.com/watch?v=8ofDiXF1HpA
Read though page 184 in your textbook with your symbol group, and identify what’s going on in the
picture.
Facts about nitrogen
The amount of nitrogen (or of water) can vary in different areas. If an area has too little nitrogen farmers
add fertilizers or plant nitrogen-fixing plants to try and solve the problem. What occurs when an area is
lacking water?

How do you identify the concentration of nitrogen, phosphorus and potassium in a fertilizer bag. Create
an example inside the “bag” and swap an example with your desk neighbor.
Think about it! Do you believe that Farms need to use pesticides and fertilizers?
Solid Wastes https://www.youtube.com/watch?v=Yg1tEKILiR4
How do we solve our trash problems?
What is Solid Waste?
Where does it go?
How do we get rid of it?
What could we do in Lac la Biche that other places are doing?
Liquid Waste
•
___________________________________________ is waste water that contains dissolved and
undissolved material from your kitchen, bathroom and laundry
•
A _________________________________________ is an underground tank where bacteria
break down organic materials
•
_______________________________________ (aka treated wastewater) is released into riversmay still contain extra nitrogen and phosphorus- this can cause alga bloom as the algae in the
water uses the fertilizers to bloom
Where does the rain water go?
Fuel Combustion https://www.youtube.com/watch?v=cJ-J91SwP8w
What is combustion?
What are Fossil Fuels? List examples
When do we use fossil fuels?
• The combustion of fossil fuels produce carbon dioxide and water vapor
o Hydrocarbon + oxygen  water + carbon dioxide + energy
Think about it: Can the carbon we release be reused? Describe where carbon can be recycled.
What do we mean by Incomplete Combustion?
What is Pollution?
Unit C 1.4 page 204-209
There are three basic ways that substances enter plant roots, and how substances move through an
environment
o
1) Diffusion
