Substitution class made use for observation under foldscope -7 A

I got a substitution class for 7 A and utilised the class for showing the students some slides like xylem ,phloem,stomata, yeast cells and water sample under foldscope .Students had an exciting session. They could also observe the movement of an unidentified protozoan which could not be captured in the photo.
