of the most important greenhouse gases.
2) chemical change: or
chemical reaction is a change that occurs when you mix substances. The mixing
results in a new substance with properties different from the original
substances.
3) dissolve: when a
substance is blended with another to create a new solution
4) fair testing: making
sure that you change just one variable at a time
5) molecule: the
smallest particle of a chemical substance. Molecules can consist of one atom or
more atoms bonded together.
6) observations:
watching and taking notes of everything (using all of the senses) that happens;
you may record using a notes, a table, chart, graph
7) particles: an object
or body
8) prediction: an answer (with reasons)
to the experiment question
9) procedure: a series
of steps that can be followed repeatedly to produce the same results
10) question: a
testable question that can be answered by conducting an experiment or test
11) results: a record
of your observations e.g. notes, numbers and illustrations
12) scientific process:
the procedure followed for scientific investigations (see mini-lesson)
13) separate:
separation is a process that changes the mixture of substances into different
products.
14) solution: a mixture
of one or more substances dissolved in another substance e.g. sugar dissolved
into water
15) substance: any
material used in a process in chemistry
1) mini-experiments:
a) read Conduct and Investigation text pp 236-239
b) complete six class-guided mini-experiments (including four fair-testing ones) using set forms
2) design your own experiment (two pages, one you complete when you try your experiment and one you set up (with materials and procedure) for your peer)
a) read Design Your Own Experiment text pp 240-241

5) vocabulary quiz
*facts and information related to experiments
Pre-lab: The Power of “Sea” Water (see why)
- H2O (water) + ClNa (salt)
- salt makes the
water denser
- denser water
supports more weight
- increasing salt
makes water increasingly denser
- when water becomes
dense enough the egg floats
#1 Curds and Whey
- milk + with C2H4O2 or Acetic Acid (vinegar)
= a chemical reaction
- the vinegar causes
the milk to separate into two parts
1) curds is
the coagulated (thickened) part of the milk
2) whey is the watery part of the milk
#2 Solid or Liquid ! (see why)
- water + cornstarch = a suspension (neither a solution nor reaction)
- when you are not pressing it, the molecules are relaxed, watery
#3 A Different Form (see why)
- CHNaO3 (Sodium bicarbonate or baking
soda) + C2H4O2 (Acetic
Acid or vinegar) = a chemical reaction, acid reaction
- when sodium bicarbonate dissoves in vinegar, it reacts with the water and forms OH which reacts with the acetic acid to form water
- the fizz is carbon dioxide
#4 Green Pennies (see why)
- Cu (copper or penny) + mixed C2H4O2 (Acetic Acid or vinegar)
= a chemical reaction
- mixture turns the penny green
- copper + oxygen = copper oxide, copper oxide makes pennies look dull and dirty
- vinegar is a weak acid and dissolves the copper oxide making a blue-green complound called malachite
#5 Naked Egg (see why seeFeb 10)
- uncooked egg + mixed C2H4O2 (Acetic Acid or vinegar)
= a chemical reaction
- vinegar changes the
calcium from a hard shell to a soft, rubbery, transparent shell

body's building blocks, different sizes and shapes (muscle cells, brain cells,
nerve cells, bone cells, skin cells, & blood cells) image
2) blood
vessels: stretchy tubes our blood travels through
3) circulatory
system: the route our blood travels through e.g. our blood vessels (arteries,
capillaries, and veins) and our heart that work together to pump blood through
our bodies (takes 26 seconds to circulate once) image
4) arteries:
these big vessels carry blood away
from the heart, rich with oxygen and food, to the capillaries
5) capillaries:
very little, thin vessels that carry the blood through our cells; as it passes
through, it carries waste products out through our breath
6) veins:
larger than capillaries, these vessels carry the blood from the capillaries
back to the heart; very little oxygen or food in this blood
7) heart:
strong, powerful muscle that pumps the blood through your body; is a two part
pump (right side takes in the blood while the oxygen-rich blood leaves out the left side to travel
through your body
8) carbon
dioxide: waste gas which is exchanged for fresh oxygen in our lungs
9) blood: the
fluid that runs rich with oxygen and food from our heart, through our arteries,
through our capillaries, then through our veins back to the heart
10) valves:
one-way doors to keep the blood from flowing backwards e.g. so the good rich
blood does not get mixed up with our waste filled blood image
11) heart
attack: when the blood stops flowing to a part of the heart
12) stroke:
when the blood stops flowing to the brain image
13)
arteriosclerosis: when the blood vessels carrying the blood get clogged,
interfering with the blood flow
14) pulmonary artery: takes the blood to the lungs, where it picks up oxygen
15) aorta:
the main artery from the heart that divides into other arteries that carry the blood to the rest of the body
16)
pulse: occurs each time your heart pumps
17) oxygen: a gas found in the air you breathe in image
18) nutrients: materials your body needs to stay alive and grow image

food down so that our bodies can use the nutrients and get rid of the waste
- uses organs that work together to keep
digestion going
- mouth, esophagus, stomach, large intestine,
small intestine
- hydrocholoric acid used by the body to help
break down food
6) circulatory system:
- heart pumps blood thoughout your body
- oxygen into lungs, blood with oxygen enters
left side of heart and onto the body cells
- from the body cells the blood travels back to
the heart, carbon dioxide filled blood travels back to the lungs
7) skeletal system:
- our framework, gives us our shape
- 4 groups of bones: skull, spinal column,
ribs, bones in arms and legs
- joints allow your bones to move
- cartilage is a gel-like material that reduces
the friction between the bone ends and your joints
8) muscle system:
- muscles are attached to the bone by tendons
and other tissues
- muscles enable us to move our body
- we can strengthen our muscles by making them
work
9) nervous system:
- gathers, stores, and controls the body's
information
- it collects information about the body's
external situation, this helps us to survive
- example: when you place
your hand on a hot stove, the nerve ends in your hand send a message to your
brain that says "move your hand!"

- one part of the rope is attached to a load
- when you pull on the rope, the wheel turns and the load is
lifted
- examples: flag poles, sailboat, blinds, crane
2) ramp:
- sloping surface
- changes the effort and distance needed in doing work,
makes it easier
- examples: staircase, bottom of a bath tub, ramp, slide
3) lever:
- a board or bar that pivots
- helps to lift a load
- the closer the load is to the pivot point, the easier it
is to move
- examples: door on hinges, teeter-totter, hammer, bottle
opener, crow bar, using a hammer to remove a nail
4) screw:
- an inclined plane wrapped about a rod
- used to hold things together
- examples: bolt, spiral staircase, jar lid, meat grinder
5) wedge:
- two inclined planes, the planes meet and form a sharp edge
- used to split things
- examples: axe, zipper, knife, a fork, nail
6) wheel:
- a larger wheel connected by an axle, the axle goes through
the wheel letting it turn
- the wheel move a larger distance than the axle but need
less force or energy to move it
- example: door knob, wagon, roller skates
