Finger Tapping Experiment: 

• Chicken wings
• explanation for the finger tapping experiment

The Experiment:

• For each finger, tap for 2 minutes. (non-stop!)
• At every 20 seconds say how many taps you have done, and restart counting again, make sure you do not stop!
• Your labpartner fills this in in the spreadsheet you have copied from classroom.
• You have 2 people and 6 fingers to test per person, so if you even take 4 minutes per finger (2 min test and 2 min setting up), the whole experiment should only take 48 minutes.
• Tip: switch lab pertners between each test so your fingers can rest.

Collecting Data:

• YOUR TITLE
• your name
• your student number
• if you have them, lab partner’s name(s) and student number(s)
• your class

Chapter 2: Materials & Method

• Materials:

All materials used in the corrent amounts and names, you can even add pictures if you wish.

• Method:

Instructions written in short clear sentences, no past tense!!

Step 2:

Chapter 3A: Data Collection

• Collect all measuements in tables in sheets (so you can make graphs). All tables, graphs and pictures must have 1-2 sentences of a description with them.

• Physical observations:

Write down all physical obeservations too, and organise these in tables too.

HW FOR LESSON 5:

• READ THE FEEDBACK YOU GET ON YOUR LAB PROJECT.
• COMPLETE THE SPREADSHEET.
• COMPLETE CHAPTERS 2 AND 3.
• Only on of the two submits the docs for feedback the other lab partner hands in a screenshot.

BROKEN BONES:

• A complete fracture - is when the bone has broken into two pieces. 
• A greenstick fracture - is when the bone cracks on one side only, not all the way through. 
• A single fracture - is when the bone is broken in one place.
• A comminuted fracture - is when the bone is broken into more than two pieces or crushed. 
• A bowing fracture - which only happens in kids, is when the bone bends but doesn't break. 
• An open fracture - is when the bone is sticking through the skin. 
  

A simple fracture:

is when the bone has broken in one place

A greenstick fracture:

is when the bone cracks on one side only, not all the way through. 

A compound fracture:

 is when the bone is broken into more than two pieces or crushed. 

An open fracture:

is when the bone is sticking through the skin. 

DISEASES:

oseoartritis

rheumatoid arthritis

osteoporosis

Osteoarthritis

Due to wear the cartilage and fluid in the joints gets worn down.

This often happens with elderly people and causes painfull joints.

Rheumatoid arthritis:

The bodies immune system attacks the fluid and cartilage in the joints.

This often happens with young people and causes painfull joints.

Osteoporosis:

Due to old age and a lack of calcium and collagen the bones become very weak. This happens more in elderly women than with elderly men.
