Simple experiment to do with one paramecium

[Paramecium8]

This is a simple experiment that you need:

Lettuce

Iodine (or something that have iodine)

Water from river or rain

Microscope

1. Place water and small pieces of lettuce in a bottle and wait a lot of days.

2. If you can see some paramecium in the water (obviously using the microscope) make a slide of the water and the iodine

3. The hardest part is finding the paramecium that creates crystals around it (not really are crystals)

the crystals are protecting the paramecium and making a cool effect

remeber posting if the experiment worked (it can fail sometimes)
