Effective enzymes pH: Could I have some info on how I do the ph for the jelly for the pineapple prac please—Exploring Human Biological Science Stage 2 Body Works Activity 27 Page 176.
Litmus Paper: The Litmus paper in our lab is many years old, but has been kept dry in a dark drawer.
pH Probe: Can anyone suggest a pH probe with data logging function/capabilities for use with our senior science groups?
Agar plates: I've been asked to make up agar plates with different pH values from 3–11—any information I can find on the net suggests the agar won't set at a low pH. Any ideas?
This online resource looks at factors that affect population growth in yeast.
The resource gives details for an inquiry that focuses on the factors that affect population growth.
