Unit 1 Basic 8
Warm-blooded and cold-blooded animals

Slide 8 - Slide

Learning goals
  • I can describe respiration in organisms and explain the relationship with physical activity using the terms glucose, oxygen, water, carbon dioxide, energy
  • I can describe the differences in respiration between cold-blooded and warm-blooded animals

Slide 9 - Slide

What is the formula of respiration (= combustion in your body)? 
Carbon dioxide

Slide 10 - Drag question

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

Slide 11 - Slide

is used for?

Slide 12 - Mind map

-Sending messages along nerves
-Building new cells for growth
-Keeping a constant body temperature
