|
A-1 |
evidence |
observations or
data to support a statement,
hypothesis, or point of view |
| |
hazardous
materials |
substances that
can pose a danger to the health &
safety of living things |
|
A-2 |
reactive |
substances
capable of causing an explosion or
providing heat or oxygen (oxidizers)
that might cause a fire, or can emit
toxic fumes when mixed with other
substances |
| |
corrosive |
(usually a
liquid) that reacts with a solid
material and chemically wear away |
| |
flammable |
any substance
substance that can catch on fire
when exposed to a spark, flame, or
heat source |
|
A-3 |
mixture |
a combination of
more than one pure substance that
can be physically separated |
| |
observation |
notes taken that
provide evidence using 5 senses |
| |
inference |
a conclusion
based on observations or what is
already or known |
|
A-4 |
toxic,
toxicity |
poisonous
The capability of a substance to
cause harm in living systems over a
period of time. |
|
A-6 |
chemical
properties |
traits of a pure
substance that you find by seeing if
it reacts in a certain way with
other chemicals. Chemical properties
include pH, the production of a salt
when an acid reacts with a metal, or
a unique color change in a chemical
reaction. |
| |
miscible,
miscibility |
two or more
substances that can be mixed
together in any ratio to form a
single phase without separation |
| |
physical
properties |
a characteristic
of a substance or material, such as
color, density, flexibility,
hardness. They help identify pure
substances and never change whether
there is a large sample or very
small sample of material. |
|
A-7 |
conductivity |
The ability of an
object to support the flow of heat
or electricity. |
| |
density |
The mass per unit
volume of an object. Density is a
physical property used to find the
identities of pure substances.
Formula for density is- mass divided
by volume. |
| |
reactivity |
The ability of a
substance to combine with another
substance that may cause an
explosion, provide heat or emit
gases. |
|
A-8 |
cubic
centimenters (cm3) |
Metric
measurement of volume, usually for
smaller amounts. |
| |
liter (l) |
Metric measure of
volume, for larger quantities. |
| |
metric
system |
The measuring
system used by scientists and most
countries other than the US. The
metric system is based on the power
of ten and to convert from one unit
to another, the decimal place is
moved. |
| |
milliliter (ml) |
Metric unit of
volume. 1000 milliliter
= 1 L |
| |
qualitative |
Description,
observation or analysis of a
substance based on its
characteristics such as color, size,
shape, etc. |
| |
quantitative |
Description,
observation or analysis of a
substance based on measurements. |
| |
volume |
The amount of
space an object or substance
occupies. |
|
A-9 |
mass |
The amount of
matter in an object. |
| |
weight |
The force exerted
by a mass as a result of gravity. |
|
A-11 |
trade-offs |
An exchange of
one thing in return for another.
Trade-offs always involve balancing
benefits against risk. |
