Hey, so for the bio prac, I examined the following:

Common spot of strawberry: dark spots on leaves and fruit of strawberry plants; caused by a fungus
African black beetles in grass: a tuft of grass was pulled from the ground; the shoots were yellow/brown, and there were bite marks around the base of the grass shoots where the beetle was biting; after some digging, some beetles were found
Aphids on lemon and grapefruit trees

Safety: staying in sun too long, wear hat/sunscreen, no longer than 30mins; don't agitate trees so that aphids won't squirt pungent liquid near where you stand

Any thoughts???
