• Identify the seven characteristic of living things and use the characteristics to decide whether something is living or non-living things.
• Discuss the difference between each of the seven characteristics of life.
• Discuss the difference between breathing and respiration

1. Movement – changing the position of all or part of the body.
animals move to :
- Find shelter
- Find food
- Avoid enemies
Muscles provides movement for all animals.
Note: Plants moves but only some parts.

2. Respiration – is the process getting energy from food, often used oxygen.
• Word equation:
• Glucose + oxygen Carbon dioxide + water
Animals – use oxygen for breathing and release Carbon dioxide
Plant – uses carbon dioxide to make food and releases oxygen as waste.

Difference between breathing and respiration
Breathing
• Movement of air into and out of the lungs.
• Takes place in and out of the lungs.
Respiration
• Breakdown of food to release energy.
• Takes place in all body cells.

3. Sensitivity – living organisms able to detect/respond to changes in their surrounding.
Main human senses: sight, hearing , smell , taste, touch, temperature detection (feeling)

4. Growth – gets bigger and stays bigger.
• Organisms change in size, shape, height and other development that takes place in an organisms

• 5. Reproduction – is the process by which organisms produce offspring.

6. Excretion – is the process of removing waste products from organism’s body.
• Waste are released in urine, sweat and carbon dioxide in air that we breathed out.

7. Nutrition - the process by which living organisms take in or make food.
(Animals cannot make their food so they take food)
(Plants make their own food – photosynthesis)
Word equation of photosynthesis:
Carbon dioxide + water Glucose + oxygen

Limewater (calcium hydroxide dissolved in water)– substance used to test the presence of carbon dioxide in exhaled air.
If carbon dioxide is present the limewater turns white or milky.
The calcium hydroxide dissolved in the limewater reacts with the carbon dioxide.
This makes the water turn white or milky.

Testing the presence of carbon dioxide in exhaled air
