HAPPY MONDAY BUFFS!!

Bellwork: Please turn in your Meal Breakdown sheets and posters to table 7 marked with your class period.

On the sheet of paper you picked up:Title: Quiz 2NamePeriodDateNumber it 1-10

SCIENCE FACT OF THE DAY: IF YOU YELLED FOR 8 YEARS, 7 MONTHS, AND 6 DAYS, YOU WOULD HAVE PRODUCED ENOUGH SOUND ENERGY TO HEAT UP ONE CUP OF COFFEE.

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!

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 different atoms bonded together

BONDS, BONDS, BONDS!

Molecules are different atoms bonded together.

The bond stores energy.

When that bond is broken, energy is released.

CHEMICAL REACTIONS

Chemical reactions are how ATOMS bond together and break apart.

When a chemical reaction breaks a bond, energy is release in the form of heat.

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.

Hint: Think red rover

DIRECTIONS FOR MAKING “GLOOP”

1. In your plastic baggie, add glue up to the baggie.

2. Add 5 ml of water to the glue.3. Add 2-4 drops of food coloring to the glue

and knead together with your hands.4. Add 8 mL of borax solution to the baggie,

MAKE SURE THE BAG IS CLOSED, and mix thoroughly.

Gloop Lab Report:

Copy what is in bold and answer the questions:

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

2. Describe how are monomers and polymers related.

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