What is Risk?
Risk is the
possibility of
consequences
involving mortality,
morbidity, or injury
to members of the
public.
What risk do we
take when we drive
our vehicles?
How much risk is safe?
There is no situation in which there are no risks,
but every situation should be as safe as
possible.
Our government allows a 1 in 1,000,000 risk for
things out of our control. For example: The
chance of coming into contact with radioactive
material.
Thing we can control are allowed a 1 in 10, 000
risk. For example: The chance of being
poisoned by a pesticide.
Where is risk relevant for
students?
Cosmetics
Detergents
Cell phones
Medications
Cleaning supplies
Pesticides
Herbicides
Transportation
EVERYWHERE!!!
Poisons Surround Us
Water
Soil
Air
Purpose
Enrichment for Chemistry and Biology
curriculum.
Alert students of poisonous products in
their environment.
Increase awareness of risks in everyday
activities.
Enhance learning by using technology in
labs.
Background Knowledge
Chemistry:
Chemical properties - those properties a
substance possesses because of its
action or lack of action with other
substances. Reaction with an acid, or
reaction with oxygen (combustion) are
just a couple of examples of chemical
properties.
Background Knowledge
Biology:
Cellular respiration - is the
process of oxidizing food molecules, like
glucose, to carbon dioxide and water.
The energy released is trapped in the
form of ATP for use by all the energyconsuming activities of the cell.
