Head Bands! (UNIT VOCAB)
• Everyone in your group should look at the headbands.
• Everyone should have completed their headband
pictures.
• You will need a 30 second timer and a half sheet of
paper (with your name on it!) to record your progress.
• Lay them face down, randomly pick one up.
• You cant say your word, or rhymes with, and only
have 5 questions to ask for clues to what word is on
your headband without looking! YES or NO questions.
You get 2 guesses at your word. Keep track of how
many total words you do and how many (including
which ones) you got correct.
• Familiarize yourself with all the words before you start.

METALLIC BOND
METALLIC BONDS form when any element in the METAL
group bond with another element in the METAL group.
Metallic bonds are WAY better than M&M’s because they
are M&M&M (Metallic bond = Metal + Metal) Get it?
Atoms: the chemistry of life.
•Distinguish
• IONIC Bond
between the 3
– the force that holds oppositely
charged ions together.
types of bonds.
•Metal ions are positive (cations)
•Nonmetal ions are negative
(cations)
•Any “salt”
IONIC BONDS form when any element in the METAL group
bond with any other element in the NON-METAL group.
Since our bodies contain IONIC BONDS – I aM aN Ionic
Bond. Get it? IMN (Ionic Bond = Metal + Nonmetal)
Atoms: the chemistry of life.
•Distinguish
• COVALENT Bond
between the 3
–SHARE 1 or more electrons
(literally)
types of bonds.
– e- share to gain a full outer
shell (8). HOMEOSTASIS.
COVALENT BONDS form when any element in the NONMETAL group bond with any other element in the NONMETAL group.
Covalent Bonds made the news on CNN. Get it?
Covalent Bond = Nonmetal +Nonmetal.
Organic compounds are COVALENT BONDS!

sugar, phosphate and
nitrogen base)

Examples are:
Function is:
To provide
INSTRUCTIONS, or
genetic code. To provide
energy (ATP)

Keratin - hair, nails.
Antibodies - kill
invaders. Enzymes carryout biochemical
reactions
Main purpose of fat is
storage, more efficient
than carbs. Barriers

Organic Molecules (macromolecules)
Carbohydrates
•Made of C, H, O in ratio of 1-2-1 (sugar)
ENERGY SOURCE!
•Can be simple (monosaccharide, sugar,
quick energy), or complex (polysaccharide,
starch, pasta/rice short term energy
storage).
•Cellulose provides structural support,
plants, becomes undigested fiber in
humans.
•Cows/horses can break down cellulose for
use. Termites
Organic Molecules (macromolecules)
Proteins
•WORKHORSE OF ALL LIFE!
•Composed of long chains of amino acids
•Proteins function determined by its 3D shape.
•Hemoglobin = protein in blood that transports
Oxygen
•Proteins provide structure: collagen = cartilage,
tendons; keratin = hair.
•Proteins act as enzymes which increase chemical
Reactions needed for growth, movement etc.
Organic Molecules (macromolecules)
Lipids
• Fats
•INSOLUBLE (wont dissolve in water) Hydrophilic
head, hydrophobic tail.
•Fats store energy, more carbon-hydrogen bonds
than carbohydrates.
•Saturated fats –solid at room temp. Are “saturated” or
“hydrogenated” with hydrogen.
•Unsaturated fats =liquid at room temp. Olive oil,
vegetable oil etc…
Organic Molecules (macromolecules)
Nucleic Acids
•Two main types: DNA, RNA. Sub units are called
nucleotides which form genes (A,C,G,T/U).
•DNA = double helix. It encodes sequence of
proteins and when they should reproduce. Made
of two RNA strands.
•DNA together with proteins called chromosomes.
•RNA (monomer of DNA)helps in the synthesis of
proteins and carry DNA’s message from one place
to another in a cell.

Diversity of Cells Lab
• Check the timer, that is how much time you have left,
it’s a Rally day.
• If you run into a question ASK ME, don’t guess.
• READ THE DIRECTIONS!!!
• Clean up your own slides when you are finished in the
front/side sinks. BE CAREFUL. Dry completely.
• Onion cell: peel off a tiny piece of the shiny skin of an
onion, or scrape knife sideways then smear on slide, 1
small drop of methylene blue or lugols solution and
allow it to soak for a few seconds. Then carefully tip
the cover slip on.
• Make sure the STAPH slide stays with your
microscope but clean up everything else.
Macromolecules worksheet
• While you start your Macromolecules
worksheet, have your notebook open for me to
check your CELL picture from the internet.
• DO NOT BE COLORING IT NOW! It should be
finished. If you are coloring it you will not get
credit.
• Have your Eukaryotic/prokaryotic WS out, also
your lab paper.
Macromolecules worksheet
• HW!!!
• Tues- Macro worksheet due, Ch. 7.1 (on
left side of NB) vocab and ?’s 1, 2, 4. quiz
on the vocab.
• Wed – Unit vocab quiz, ch. 7.2 (on the left
had side of NB) vocab and ?’s 2, 3, 4, 5

CELL as a metaphor
•What did we miss?
• What do YOU think that part could be?
•Bring colored pencils, tomorrow you will create your
OWN cell as a metaphor poster.
•Start thinking of something UNIQUE to represent the
Cell as.
•I will put you in groups to work together to create
something MAGICAL! 
