BODY COORDINATION ASSIGNMENT

Choose two of the following topics.
You must choose one from Part A and one from part B:
PART A
Make a Model
Make a three-dimensional model of a neurone. Refer to diagrams in the text and on line. Label and define the purpose of parts of a neurone.
Hints: Use string, beads, dry pasta, plasticine or any material you think suits this task. Magazine or Television Advertisement.
A commonly held belief is that chocolate is addictive due to certain chemicals in the chocolate. Most studies that have been carried out are inconclusive and suggest chocolate simply tastes good. Research to present your findings in the form of an advertisement for a brand new chocolate bar. Make references to the ingredients and their effects on the nervous system. ie Brain and senses.

Short Story
W rite a short story in which as many stimulus-response examples are given. After each description, identify the stages in brackets. Example: The alarm clock buzzed (stimulus) and Daniel heard (receptor) it. So he lifted his arm (effector), picked up the alarm clock and hit the snooze button (response). He was awake now and knew it was time to get up (stimulus and receptor), so he used his stomach muscles (effectors) and rolled to the side of the bed (response) and stood up. Time for breakfast, he thought.

Experiment
Design your own experiment to determine how your body responds to changes in temperature. Use a thermometer to measure skin temperature inside a bent elbow and internal temperature under the tongue. If you have access to an electronic clinical thermometer, measure internal temperature at the ear. Record any observations about how your body responds in a table similar to the one shown below. Eg. Lying still. Putting on more clothes. Exercise. Standing in front of an air conditioner etc. Example.

Activity

Internal
Temperature
37 °C
Exercise
37 °C
Clothed
Air conditioner 78 °C

External
Temperature
30 °C
30 °C
25 °C

W rite the experiment as a Practical Report.

Observations
Sweating, increased heart rate
Sweating, increased heart rate
Shivering, goosebumps

PART B
Diabetes
Research the incidence of diabetes in Indigenous and non-Indigenous Australians. Explore resaons for the difference. Present this information as a comparison table or a short essay. MRI
Read and research about MRIs and issues associated with trying to ‘heal’ brain injury or tumours.
Research brain tumours or brain injury
Find how the MRI detects these injuries
What medical treatment exists for these injuries? Focus on non-cancerous or benign tumours. Any other interesting information.
Effects of caffeine, alcohol and nicotine on the nervous system. Research the effects of caffeine, alcohol and nicotine. Discuss reasons for people using these substances. Discuss the consequences for the nervous system for abusing them. Consider the question: If decisions were made today, would caffeine, alcohol and nicotine be classified as legal drugs?

Hormones
Choose a hormone involved in the endocrine system. Find out: Where it’s produced?
What its target cells are?
What it does in the body?
What happens if too much is produces?
What happens if not enough is produced?
What its advantages and disadvantages are?
How it fits in the body?
