HAPPY MONDAY BUFFS!!

Bellwork:(Have out your HW)

Anticipation Guide: Write down “Agree” or “Disagree” for each

statement.1. I love to bake cakes.

2. If you leave sugar out of the cake it, it will taste the same.

3. I like to eat cookies with milk.4. If you mix glue and water, it will

make a liquid.5. A polygon has more than one

side.

CO: I will understand how Polymers are made.

LO: I will write notes on Monomers and Polymers

and participate in the “Gloop Lab”.

BIOMOLECULES (A QUICK RECAP)

BIO = LIFE MOLECULE = ATOMS BONDED TOGETHER

4 major biomolecules:1. Carbohydrates2. Lipids3. Proteins4. Nucleic acids (we will talk about this one

later)

Biomolecules are molecules that are essential for life

We find biomolecules in our FOOD!

Title: Gloop Lab and Polymers

Essential Question: How are large molecules formed?

Set up Cornell Notes. The underlined words will need to go on the left.

BIOCHEMISTRY: THE CHEMISTRY OF LIFE

Matter: anything that takes up space

Atom: basic unit of matter, building block of a molecule

Molecule: two or more atoms bonded together

CHEMICAL REACTIONS

Chemical reactions are how ATOMS

bond together and break apart.

PARTS OF A CHEMICAL REACTION

Reactants: what goes INTO the chemical reaction, left side of arrow

Products: what is produced from the reaction, right side of arrow

Arrow: “yields”, makes

Chemical Reactions in a Cake

MONOMER Mono = one Monomers are small molecular units that

can be combined to make larger units.Monomers are the subunits of polymers

POLYMERS Poly = many Polymer = a large molecule made by

bonding smaller molecular units (monomers) together

Monomer + monomer + monomer +…= polymer

What is the monomer in the above polymers pictured?

EXAMPLES OF BIOLOGICAL POLYMERS INCLUDE: Proteins, Complex Carbohydrates,

Lipids, Nucleic Acids (DNA)

Dehydration synthesis = a process through which polymers are formed from monomers through the removal of H2O.

Hydro=water Lysis=cut

Hydrolysis = the process of breaking down polymers into monomers by the addition of H2O.

DIRECTIONS FOR MAKING “GLOOP”*DECIDE ON ONE “MATERIALS PERSON” PER TABLE, THIS IS THE ONLY PERSON ALLOWED TO LEAVE THE LAB GROUP*

1. In your plastic baggie, add glue up to the 1 cm line (Use a ruler: CM not Inches).

2. Add 2-4 drops of food coloring to the glue and knead together with your hands.

3. Add 7mL of water to the baggie using the marked graduated cylinder and mix thoroughly.

4. Add 8 mL of borax solution to the baggie using the syringe and mix thoroughly. (Mix the solution in the beaker before using.)

Gloop Lab Report:

Copy what is in bold and answer the questions:

1. When we added water, what process was occurring: dehydration synthesis or hydrolysis? Describe the glue after water was added.

2. When we added borax, what process was occurring: dehydration synthesis or hydrolysis? Describe the glue after borax was added.

3. Summarize what happened during the Gloop Lab in 30 words. You must use the words: polymer, hydrolysis, dehydration synthesis
