What is alcohol? There are many different alcohols but the one that we can drink is ethanol – the active ingredient in alcoholic drinks.

Alcohol is quickly absorbed into the bloodstream, where it starts to have an effect on the CNS.

The effects of alcohol vary from person to person and with factors such as:

rate of consumption level of food/water intake

body weight/body fat.

age and gender

Most students will be able to explain the effects of alcohol on the body

• Small amounts of alcohol cause a person to feel relaxed and less inhibited. ( life and soul of the party)

• More alcohol has a depressant effect, making reactions uncoordinated and impairing speech. (you fall over and talk drivel)

• Alcohol is a diuretic, which means it causes more urine to be produced than normal. (helps the hangover get worse and you pee a lot)

• Alcohol also makes blood vessels dilate, leading to heat loss. ( dangerous for rough sleepers)

Short term effects

• Reduces inhibitions

• Depressant – lose co ordination

• Slows down reaction times

• Acts as a diuretic

• Blood vessels dilate

Most students will be able to explain the effects of alcohol on the body

• Alcohol slows down reaction times, gives a false sense of confidence and affects a person’s decision-making ability. (you will sleep with anybody who isn’t Quasimodo)

• At high levels, alcohol causes vomiting, unconsciousness and can even cause breathing to stop and lead to death. ( no jokes for this one. Mums screaming ‘No it can’t be’ is not funny)

Close your books -

Working with a partner -

• Give two factors that can affect the way the body handles alcohol ?

• Explain why these factors have an effect.

• Name three short term effects of alcohol on your body.

Like all drugs, alcohol is broken down, or metabolized, by the liver.

The long-term effects of alcohol

Heavy drinkers are also at increased risk of cancer and damage to the brain, kidney and immune system.

Over time, heavy drinking damages liver cells, causing them to produce fibrous scar tissue which blocks liver function. This is a disease called cirrhosis.

Long term effects

• Affects decision making

• Vomiting, unconsciousness

• Breathing stops – death

• Cirrhosis

• Mental health problems, stomach ulcers

Foetal Alcohol Syndrome

Most students will be able to explain the effects of alcohol on the body

• Describe two possible long term effects of alcohol on the body.

• Explain why it is not a good idea to drink during pregnancy.

All students will be able to produce a line graph

Most students will be able to produce a line of best fit.Most students will be able to interpret the graph by answering

questions on it.

• Task 1 – draw a line graph on the work sheet using the data given.

• Task 2 – answer the questions in detail, interpreting the graph.

• Task 3 – identify the independent and dependent variables for the data. Are they continous? What should have been controlled if the experiment was valid?
