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).

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

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.

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.
