LO: SWBAT differentiate between organic and inorganic molecules DN: What elements are all living things made up of? HW: due monday page 48 # 1,2,5

What elements are all living things made of? Carbon, Hydrogen, Oxygen, Nitrogen COHN

When atoms bond together they are called…… MOLECULES Join

Bonds store energy When is energy released? Bond must be broken to release energy.

Formulas CO 2 A chemical formula represents the chemical makeup of a compound or molecule. How many carbon atoms in 1 molecule of CO2? How many oxygen atoms in 1 molecule of CO2 ? 1 2

How do we write chemical compounds using symbols? What is H 2 0? How many hydrogen atoms in 1 molecule of water? 2 How many oxygen atoms in 1 molecule of water? 1

Structural Formula Structural formula shows the kinds, numbers, and the arrangements of atoms. It also shows the bonds Bonds

Chemical Equations and Reactions A + B C or C A + B Raw materials Products

Example of a Chemical Reaction: C 6 H 12 O 6 + O 2 6H 2 O + 6CO 2 GlucoseOxygenWater Carbon dioxide Which are the raw materials? Which are the products? How many water molecules are produced? How many glucose molecules are used? How many carbon atoms are present in a molecule of glucose? 6 6 1

Types of molecules Organic Inorganic

What do organic molecules have in common? C & H Examples Carbon and hydrogen

C O What do inorganic molecules have in common? C OR H OR neither

Organic Have C & H together Made by living things Inorganic Have C or H or neither, but never both at the same time. Can be found in living things Organic vs. Inorganic

Organic compounds are made by Living Things CO 2 + H 2 O O 2 + C 6 H 12 O 6 inorganic organic
