Unit 1 Basic 1-3

Slide 1 - Slide

Do's during instruction
Always have: your textbook, workbook and pencil case with you
Take notes: Taking notes is learning 
Make drawings and sketches
*During learning it clarifies and visualises the subject 
Make a glossary
list difficult/biological words, use a dictionary


Slide 2 - Slide

Breathing and respiration

Lesson 1: Combustion and respiration 

Slide 3 - Slide

Some questions: 
  • What do you need for combustion (burning)?
  • What is produced by combustion?
  • What are the starting substances in our body for combustion?
  • What do we do with the products? 

Slide 4 - Slide

What is the formula of respiration (= combustion in your body)? 
->
Glucose
Oxygen
Energy
Carbon dioxide
Water

Slide 5 - Drag question

Combustion in your body = respiration
Getting energy from food 
  • Our fuel is glucose
  • Oxygen is needed to break down glucose (breathing)

Because oxygen is needed we call it:
Aerobic respiration 

Slide 6 - Slide

Energy in our body is used for?

Slide 7 - Mind map

Using energy
-contraction of muscles
-Transporting chemicals
-Absorbing food
-Sending messages along nerves
-Building new cells for growth
-Keeping a constant body temperature

Slide 8 - Slide

Where in our body is energy produced? 
I’m a real “powerhouse” 
That’s plain to see
I break down food
And release energy 




Slide 9 - Slide

Where is the energy produced?

Slide 10 - Open question

Carbon dioxide 
  • Waste gas made in respiration
  • becomes toxic if it builds up in cells
  • we need to get rid of it....



Slide 11 - Slide

Testing for carbon dioxide
  • Lime water goes cloudy when CO2 is added

Slide 12 - Slide

Cold- and warm-blooded
cold-blooded: the body temperature is roughly the same as the temperature of the surroundings -> little respiration in cold areas -> little energy
warm-blooded: body temperature is constant (always the same) -> enough respiration -> high energy

Slide 13 - Slide

Which statement(s) are true about cold-blooded animals
A
temperature is always 37 degrees
B
reptiles, insects, birds
C
hibernation=winterslaap
D
migration

Slide 14 - Quiz

How do we call combustion in your body?

Slide 15 - Open question

Carbon dioxide is released through breathing
A
true
B
false

Slide 16 - Quiz

You can indicate oxygen with lime water
A
true
B
false

Slide 17 - Quiz

Why can't we hold our breath for long?
