Investigating Human Respiration Kit


Explore The Role Of Respiratory System In Regulation Of Blood Gases

  • Creating Models Is One Way To Understand And Communicate Scientific Information
  • Examine Human Respiration
  • Time Required: One To Two 50 Minute Class Periods
Using bromothymol blue (BTB) as an indicator, students conduct a qualitative investigation. The amount of carbon dioxide in their exhaled breath is then quantitatively measured using the indicator to perform a simple titration. The combination of these steps demonstrates the function of the lungs in providing surface area for oxygen to enter and carbon dioxide wastes to leave the blood.

Ordering information: Kit contents include: Teacher’s Guide with SDS, Student Worksheets and Guides, plastic cups, Bromothymol Blue (BTB) Indicator, Sodium Hydroxide, SEPUP trays, droppers, stir sticks, cups (30mL, graduated), plastic bags (1 gallon), and straws.
