This is a guide for how and when to use absolute and relative uncertainties- If anyone is like me, well I had a lot of trouble initially in my lab reports due to uncertainties but this really helped me understand thing much better!
Hi, this is a lab report on a osmosis experiement using potatoes.
Due to the concentration of sucorse presnt in a solution, we were to find how much water entered the potato and how much water left the potato. Find out the osmotic balance, where no water would enter or leave the potato.
It was done for Biology HL and I had maiximum grade, hopeit is useful.
This file contains many useful websites and information for understanding how to use Excel for diagrams, statistical tests (the t-test). It is directly relevant to Biology Lab Work, but can be used for other IA such as for Geography Fieldwork.
