This 37-slide PowerPoint presentation covers 'Topic 6.4 - Gas Exchange' in the NEW IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into 3 sections:
A - Ventilation
B - Alveoli
C - Lung Cancer & Emphysema
The presentation itself contains minimal information as it is intended to be used with
teacher guidance. Several slides have images only so that the instructor can introduce or review a topic without the students focusing on text. They slides are formatted to be visually pleasing and to also print well for handouts or revision.
Please see the preview file for a look at all the slides.
There is also a website that I use in conjunction with the presentation, which you can freely access at:
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
