PRODUCT DESCRIPTION

This is a great lab to make cellular respiration less abstract for students. For my middle school student, this lab was their first time seeing an indicator and they were very excited about it! In this lab, I wrote the conclusion in close sentences to support my special education students.

This Product Includes:
♦2 page guided web research researching 4 articles (following QR Codes and/or Web URLs)
♦2 page guided lab report
♦1 page Teacher Guide

About This Lab:
The students time how long it takes for the Bromothymol Blue solution (a CO2 indicator) to change from blue to yellow (due to the CO2 in their exhaling) by blowing bubbles in the container using a straw. The students then complete a brief workout (a minute of jumping jacks should do the trick Or some jump-roping.)
You want their heart rates up and heavy breathing (But not to the point they are gasping for air or exhausted or need to get a drink, they will then be too tired to blow through the straw for part II). The students then time how long it takes for the Bromothymol Blue solution (a CO2 indicator) to change from blue to yellow (due to the CO2 in their exhaling) after they have exercised. (Again they get the CO2 into the solution by blowing bubbles into it through a straw).

Results of this Lab:
The indicator really works! For example, before working out it took me 16 seconds to change the Bromothymol blue to yellow. After working out it only took 6 seconds.

MATERIALS YOU WILL NEED:
♦goggles
♦2- 250mL beakers (to label #1 and #2)
♦water (100 mL)
♦1 straw
♦stopwatch
♦graduated cylinder (for Bromothymol Blue)
