In conclusion: Substances that make living things, also burn.
What does “burning” mean?
Substance + O2 CO2 +H2O+heat
A substance that burns, does this:
Since it breaks down to carbon dioxide and water, the substance must contain carbon.
Initial heat
ORGANIC substances are made out of C, H, and sometimes O, N, more. Organic substances burn.
Organic substances: •In nature, they originate from living organisms. (Today – many are synthetic).
Making Molecules from Marshmallows:
White - HydrogenGreen - NitrogenPink - Carbon

Connect according to the drawing, attach model to a white paper, add information from back of the card.
Orange - OxygenDouble bond
In your notebook: -Draw your molecular model as on the card.
-Circle one atom-Copy the details on the card.
Observe the molecular models:1.What do the marshmallows and
toothpicks represent? 2. How many bonds
(connections) do C, O, N and H always make?
3. Write at least two facts that describe the structure of the modeled molecules.
Almost all molecules that make a living organism are made from monomers, connected into large polymers:
Mono-mer(subunit)
Poly-mer
Draw a brace map of a polymer..

Fill in as much as possible
Brace maps show relationship between whole and parts.Use brace maps to show the following connections:1. “Our body is made out of organs.”2. “Polymers are made of monomers”3. “Molecules are made of atoms.”4. “Living things are made out of
water, proteins, carb’s, lipids, and DNA.”

Analysis: 1. List the four major types of
biomolecules, and for each – name its parts / monomers.
2. For each type of monomer, name two examples.
3. For each type of monomer – draw the common part.
4. Which molecules here are made of more than one subunit?
5. Which type is the most varied?
Observe the molecular models:1.What do the marshmallows and
toothpicks represent? 2. How many bonds
(connections) do C, O, N and H always make?
3. Write at least two facts that describe a parts-whole relationship.
A closer look at the moleculesWork with drawings of molecules:
1.Color: Oxygen - Red, Nitrogen – Blue.
2. Cut out the drawings. Sort the drawings into FIVE groups.3. Glue the grouped molecules onto a paper, as organized as you can.4. Give each group a title.

In regards to yesterday’s model building:
1. What did you learn that you otherwise would not have learned?
2. What questions do you have about biomolecules? (None is not accepted)?
3. Compare the two models – of a polysaccharide, and a protein.
3-dimensional models:Carbohydrates
1) Per group: build a glucose molecule from the parts:Carbon = blackOxygen = RedHydrogen = WhiteBond = tube2) Per class – connect to make a cellulose!

Proteins
Carbohydrates
Lipids
Nucleic Acids
Subunits:
Amino Acids
Mono-Saccharides
Fatty acids + Glycerol
Nucleotides
Protein

Lipid
Nucleic acid
The four major types of organic compounds (bio-molecules) of the cell:
(myoglobin – the muscle protein)
(Starch)
(Fats)
(DNA)
“Proteins run our life!”
Subunits: Amino acids20 kinds of them:
R-Group
The order of amino acids determines the 3 dimensional shape of the folded protein:
(Each letter represent a different side group)
The shape is critical for the function of the protein!
Carbohydrates – The fuels of life!
Subunits: Mono-saccharides(pronounced: sacarides= sugars)
For example: Glucose, Ribose
Poly-Saccharides:
Cell Membrane:
Subunits: Fatty Acids, glycerol
Lipids ‘draw’ the cell (by avoiding water..)! (Not a chain..)
Nucleic acids carry the genetic information!
Subunits: Nucleotides (4), A, C, G or T.
Stable!

Macromolecules:
Polymers, which are chains of smaller molecules -
Monomers = Subunits
Using the arrow code (‘part of’, ‘example of’), organize the following terms in one concept map:
Amino acids, carbohydrates, proteins, biomolecules, starch, monosaccharides, polysaccharides, glucose, proteins, lipids, nucleic acids.
Use notes, Reader page 25-28

2. Which of the four types of biomolecules does each of them belong to?
3. Organize these molecules in a concept map, using the arrow code (‘part of’, ‘example of’). Add other terms, if needed.
1. The English language contains hundreds of thousand words. But it uses only 26 letters. How come?Apply your answer to #1 to the following: 2. All living things are made of ‘just’ four types of molecules. How come living things differ so much from one another?
