Lesson: Pass out the Types of cells handout and go through the types of cells ppt. After that ask the question: What are the two most important organelles? (Nucleus and Cell membrane). We are going to look a little closer at the cell membrane and why it is so important. In order to do that we have to have a basic understanding of its properties. Playing with bubbles will allow us to do that. Separate the class into 8 groups. Pass out the bubble lab sheet. Each group needs a tin pan, a string-straw apparatus, a dixie cup, string, and bubble solution. They are to complete the lab using their group members and 6.2 in their book. This lab introduces them to the properties of the cell membrane. They are to turn the lab in when they are done.
