Biochemistry- Biomolecules

Children love to learn, but at some point they lose that and become adults that don't like formal learning. Let's explore why "play" has gotten such a bad rap and figure out how to get it back in education.

First Problem: http://xkcd.com/657 Biomolecules and macromolecules revealed what if LOTR was a
course or a textbook? How DO
children
learn? they
give
it a
try they push at boundaries The brain is
ready to learn
by filling in blanks We tend to LIKE something if we are able to "see" the patterns in it When this happens, we begin to "groove" in the patterns ... to seek them out and to expect them. conscious thought the brain
functions
at three levels
of thinking making lists
recalling facts
mathematical
assigning values Enzymes An enzyme is a biological catalyst. It quickens (speeds up) chemical reactions. "Fun from games arises out of mastery. It arises out of comprehension. It is the act of solving puzzles that makes games fun. In other words, with games, learning is the drug." - Raph Koster, A Theory of Fun "Boredom is the brain casting about for new information. It is the feeling you get when there are no new patterns to absorb." Flower Power Factortris http://bit.ly/9uhSJF http://www.funbrain.com/ Math Baseball http://www.mangahigh.com "the best instruction hovers at the boundary of a student's competence" - Andy diSessa, Cognitive Scientist [Video games] tend to encourage players to achieve total mastery of one level, only to challenge and undo that mastery in the next, forcing kids to adapt and evolve. - Dr. James Gee, University of Wisconsin
Wired Magazine, 2003 -Rath Koster, A Theory of Fun DNA Song Function: Nucleotides are responsible for encoding genes and gene expression. This essentially means that they are responsible for offspring inheritance http://www.flickr.com/photos/dinah/239650274/ 2 5 28 Think like a Babylonian [ !?*!? ] 75 12 59 60 35 61 Babylonian

for the game (learning) up front. the act of
mentally
mastering
a problem fun some games just make games lame IBL is great,
in theory, but ...
time-consuming
in reality. Designing and using activities where students learn new concepts by actively doing and reflecting on what they have done. The guiding principle is that instructors try not to talk in depth about a concept until students have had an opportunity to think about it first (Hastings, 2006). Inquiry-based Learning addition & subtraction of integers simplifying like terms
3x+4+2x-7 multiplication and division of integers solving
one-step equations

do we want
our students'
brains to be? why did
you go in to teaching? AHA moment =
the brain having fun See if you can figure out Babylonian without the "cheat codes" On linear learning paths,
students often get stuck
because of
one concept. autopilot reflexes

boredom
and frustration sorting and packaging associative

"common sense" Biomolecules #1: Carbohydrates:
Used for energy
Monomers- Glucose
Polymers- Starch, Glycogen (in animals), Cellulose (in plants) Revelation #2: BIOMOLECULE #3: PROTEINS
Monomer-amino acids least 20 amino acids needed
Polymers-structural and structural proteins
*Used as building blocks
*cell parts
*enzymes Lipids-
*Long term energy storage
Monomer- glyercol and fatty acid

Polymer- fats, oils, waxes, phosopholipids

learning
is fun PLAY what is ? illustrations by
Mat Moore Enzymes join with molecules within our cells called substrates. The exact place where the substrate and enzyme join are called active sites. As the enzyme and substrate join- the reaction is sped up. How does this happen?
Through chemical reactions produced by the enzyme and substrate and yet, children learn a remarkable amount before
they ever enter

have taken "fun"
out of learning. addition & subtraction of integers simplifying like terms

(and I suspect your discipline is similar) learning ^ So ... what can
we do? http://bit.ly/PlayLearn http://www.kwarp.com/portfolio/grammarninja.html Grammar Ninja Vocab Sushi http://www.vocabsushi.com/ http://lab.andre-michelle.com/tonematrix Tone Matrix You don't have to

we are very young ... Surely, we can
take advantage of
this in adult learning though it may require us to stretch our minds a little If we're not careful,
we're going to take
ourselves out of
learning too. Unfortunately, most
formal education focuses on
surface-level learning Bloom's

Maltose – in grains (glucose, glucose)
Lactose – in milk (glucose, galactose)
Sucrose – table sugar (glucose, fructose)
Lipids are composed primarily of fats and glycerols and normally have a chain of three fatty acids and are long chains of:
-hydrocarbon chain (nonpolar)
-carboxyl group(polar)
-glycerol The four types of triglycerides are:
Saturated, Monounsaturated, Polyunsaturated, and Hydrogenated Fats

Saturated: made from long chains of C-C bonds. These can be derived from animal fats or tropical oils (think coconut). RAISE cholesterol levels.
Monounsaturated: made from one C=C bond. Found in plant oils and can lower cholesterol level.
Polyunsaturated: more than one C=C bond and are also found in plant oils
Hydrogenated fats: made by adding an extra H to unsaturated fats. This is
found in junk foods and why companies can claim that they have no BAD saturated fats. Saturated Fats and Oils Mono and Poly unsaturated Hydrogenated fats Amino Acids-
these are configured using RNA, which are made using DNA Remember that organic compounds are made of :
Monomers: single units of a compound

Polymers: made from monomers by dehydration synthesis

Isomers: monomers that look identical bu
act differently Introduction from Boakye Glucose Functions:
Main source of energy (food) for all organisms.
Building block for cell walls
Used for structural support in organisms. What it looks like: Remember:
When lipids are present in living things, they are used to store energy and are used to form the cell membrane.
Examples of lipids are- fats, oils, or waxes Structure of Amino Acids The END... for now Since each type of enzyme has a specific duty, they are susceptible to many environmental factors. If an enzyme is made ineffective, the reaction is slowed down, eventually making the reaction stop.

Enzymes are slowed by-
A change in temperature
A change in pH levels
A change in salinity pH and temperature
