Breathing and respiration
Lesson 4: Respiration project + Quiz

Slide 1 - Tekstslide

Discussion of hw
PPC 7

Slide 2 - Tekstslide

PPC 7: Depth of breathing
1. 400 cm3
2. Inspiratory reserve volume
3. 3500 cm3
4. 2 seconds
5. 4500 cm3
6. Residual volume

volume of air that remains in the lungs after maximum forceful expiration

Slide 6 - Video

Hyperventilation
-Reduction in CO2 
-Low CO2:
 narrowing blood vessels that supply blood to the brain (dizzy)

Hypoventilation -> Reduction O2

Breathing signal to brain -> too much CO2 in the blood

Slide 21 - Quizvraag

Experiment 1: What effect does exercise have on breathing rate? 
What do you need to do? 
  • Compare breathing rate at rest vs. low vs. high exercise 
  • Think about what type of exercise you want to compare
  • Make a documentary about the process (lab report style) 

Slide 22 - Tekstslide

Experiment 3: What makes dough rise faster? 
  • Yeast contains enzymes breaks down sugar in flour
  • CO2 is formed -> air bubbles -> bread rises 

What do you need to do? 
  • Design an experiment where you vary amount of ingredients
  • Compare two mixtures 
  • Give answer to your research question (you can use above)
  • Make a documentary about the process (lab report style) 

Slide 23 - Tekstslide

End product: Lab report documentary
CH1-Introduction
CH2-Method and procedures
CH3-Results / observations / calculations
CH4-Conclusion / discussion / evaluation

-Use the quide lines on classroom! (how to write a lab report)
-Use the rubric (this will be used to score your project)
-Ask questions!
