SPECIFIC BEHAVIORAL OBJECTIVES:
Cognitive:
The
student will examine facts on tobacco.
The student will
examine effects of tobacco.

CONTENT OUTLINE:
I.
Tobacco
A. What is tobacco?
i. a
powerful drug which comes from the leaves of the tobacco plant.
ii. The leaves of the plant are dried, aged
for two or three years, and then used to make cigarettes, cigars, pipe tobacco, chewing tobacco,
and snuff.
iii. Facts
1.
Changes the chemistry of the brain
2.
About 50 million people in the US smoke tobacco on a regular basis
II.
Chemicals in Tobacco
A. Nicotine – an addictive drug that is found
in all tobacco products.
i. Affects smokers brain in the same way as
heroin or cocaine
ii. The tobacco user constantly craves more
nicotine
iii. Nicotine makes the user feel more
relaxed and more alert
B. Tar – a dark, thick, sticky liquid that
forms when tobacco burns
i. Several substances in tar are known as
carcinogens (cause cancer)
ii. Poison contained in tar and tobacco are
arsenic, benzene, formaldehyde, and hydrogen cyanide.
iii. Tar can cause cancer, emphysema, and
other diseases.
C. Carbon Monoxide – is a colorless, odorless,
poisonous gas that is produced when tobacco is burned.
i. Passes through the lungs and into the
bloodstream.
ii. Reduces the amount of oxygen the blood
cells can carry.
III. Facts and effects of tobacco
1.
Irritates the eyes
2.
Finger nails become stained
3.
Lungs receive less oxygen
4.
Stains your teeth
5.
Breath smells
6.
Can cause mouth or throat cancer

METHODS/LEARNING EXPERIENCES:
Introductory:
(5 minutes)
Welcome
the class. Take attendance. At The Bell
question, refer to attachment. Hand back any student work during
this time. Go over at the bell question,
and ask students who would like to
share their answers.
Developmental:
(35 minutes)
Start
the lesson by informing students they will be moving around the classroom in groups today going to different
stations. Go over the stations with the
students and what they are going to
do at each.
Station #1 – Simulated
Blood Vessel Restriction/Heart Rate Increases
·
One child pumps the bicycle pump. Another child
tightens the C-clamp on the pump hose. As the clamp tightens, it will get
harder to pump. A third child continually tells the first child to “pump
faster.”
Station #2 – Simulated
Blood Vessel Restriction
·
Fill all six glasses with equal amounts of
water. Put the large diameter straws in three of the glasses. Put three very
small diameter straws in the other three glasses. On the word “GO,” have six
children begin to drink as fast as they can (as if it were a race). Time them
using the stopwatch.
Station #3 – Obstructive
Properties of Tar
·
Place the funnel in the jar. Line the funnel
with filter paper, and pour in the water. Note how quickly it flows through.
Remove the wet paper.
·
Coat another piece of filter paper with molasses
or other tar-like substance and place it in the funnel. Pour water into the
filter, noting how slowly the water flows through the coated paper.
Station #4 – Oxygen/Carbon
Monoxide Simulation
·
Place the coffee grounds in the bottle of water
and shake it up. The coffee colors the water very slowly. This represents
oxygen in the blood.
·
Now add one drop of food coloring to the same
bottle. Note how quickly it colors the water. This represents CO as it enters
the blood.
Station #5 – Showing how nicotine is poisonous
·
Put two
cigarettes in a jar of water. The
nicotine will dissolve in the water and make it poisonous.
Station #6 – Memory Game
·
Students will see how many matches they are able
to get about facts and effects of tobacco by flipping over playing cards.
After
going over the stations, the teacher will split the groups up into groups of 4
and 5. Teacher
will then send students to their station and let students know when they are
able to start. After about 2 – 3 minutes at the station the
teacher will then have students rotate around the
classroom to a new station. After going
to all stations students will sit back down in their seats and discuss as a class what they discovered at each
station.
Culminating:
(2 minutes)
End
class by asking students to write on a separate sheet of paper how the body is affected by tobacco. When the students are done they will hand in
their answers and wait for the
bell to ring.
