For the next two weeks we are going to look at why life couldn't exist without chemical reactions. To start, we are going to review balancing equations and learn more about the basic elements of life - Oxygen, Carbon, Nitrogen, Hydrogen, Phosphorous . Keep your work in your class notes section of your binder.

Activity 1 - Do the balancing equations problems on worksheet 1 using this website
Activity 2 Learning about Carbon

1. Write down the element symbol, atomic number and atomic weight.
2. Write down where it can be found in nature
3. Scroll down and write a description of what the element looks like
   

Activity 3 Learn about Carbon and biology - answer these questions

1. How much is in your body - (change it from kilograms to pounds before calculating)
2. What is the ppb of the element in the human body?
3. What is the biological role of the element?

Activity 4 Learning about Oxygen

1. Write down the element symbol, atomic number and atomic weight.
2. Write down where it can be found in nature
3. Scroll down and write a description of what the element looks like
