5. Lesson 7: Molecules of life
Proteins
Composed of long chains of molecules called amino acids
Form parts of your skin and muscles
Help carry Oxygen throughout body

6. Lesson 7: Molecules of life
Lipids
Known as fats and oils
Insulate body from cold
Protect and cushion nerves
Important source of energy
Body stores extra energy as FAT

7. Lesson 7: Molecules of life
Carbohydrates
Main fuel that your cells “burn” to get energy
Ex – bread, pasta, rice, potatoes
Most basic carbohydrates are sugars – Glucose, Fructose, and Starch

8. Lesson 7: molecules of life
Big Idea #2 – Organic Compounds VS Inorganic Compounds

9. Lesson 7: molecules of life
Organic Compounds
Most contain Carbon
Found or produced in living things

10. Lesson 7: molecules of life
Inorganic Compounds
Usually DO NOT contain Carbon
Produced by humans or in laboratories

11. Lesson 7: molecules of life
Big Idea #3 – Living things are mostly composed of
just a few elements:
Carbon
Hydrogen
Oxygen
Nitrogen

13. Lesson 8: Reaction Rates

14. Lesson 8: Reaction Rates
Big Idea #1 – There are 4 ways to increase the rate of a chemical reaction
Increase the temperature
Increase the surface area
Increase the concentration
Add a catalyst

15. Lesson 8: Reaction Rates
Big Idea #2
All chemical reactions require a certain amount of ENERGY in order to break existing bonds in the reactants and form new bonds in the products
