Two IB Bio Labs in One Day!

IB Bio is starting of the week with lab work.  Year 1 HL students with Mr. Zacharda are working on a lab exploring the affect surface area and volume have on diffusion rates in agar cells.  Using blocks of agar infused with Phenolphthalein indicator, students will test the how the two variables affect the rate of diffusion of the indicator.  The data for each class is then shared with the entire class using Google Sheets for comparison reasons.

Year 2 HL students with Mrs. Schray are working through a lab measuring the rate of transpiration in kidney bean seedlings.  Students are using a photometer to measure transpiration rates.  Just as in Year 1, students will analyze their data as a class using Google Sheets.
