We are now finished with Module 3, Kingdom Protisa
In this module the students looked at prepared slides. Below are a few of the slides they viewed. While viewing the students were to identify certain parts of the organism.
Next are Diatoms. Subkingdom Algae. One of my favorites, because they come in a varity of shapes. These are single cell organisms and sometimes form colonies. The cell wall is very hard and remains when the cell dies. This substance is used in most toothpaste as an abrasive to clean teeth. Neat!
Next is an Amoeba. Subkingdom Protoza. These things are so cool! They use their pseudopods to surround their food, which makes a food vacuole to digest the food.
Here is an excellent video of an amoeba eating.
The students are required to draw and label each type of organism, under each magnification. They actually do a good job of drawing. I am impressed.
Module 4 coming up soon!
