Unit I- Life’s Building
Unit II-Energy &
Matter for Life
- Very primitive cell structure that lacks cell organelles
- Kingdom monerans (blue-green algae and bacteria)
- Cells that have a nucleus with DNA inside and other cell organelles
-1celled organisms such as Paramecium,Amoeba,and the Euglena (Kingdom protista )Key Idea 2-Simple Organisms lack a cellular organization and can either be prokaryotic or eukaryotic.
Do they really work?
Research on Antibacterial Soaps:
place bacteria in three different culture dishes. Bacteria can come from the soil or from your hands. If you use soil use the Q-tip to transfer the soil into the culture dish.
3. Label one of the dishes the control. Place plastic wrap over it and use a rubber band to hold it in place. Set this aside.
4.Put the two different soaps in the remaining two culture dish (one soap in each dish).Procedures
Culture dish – All of the bacteria were exposed to the same growth medium.
Source of bacteria – Each dish is filled with soil from the same plant.(If you use your hands as the source of bacteria it should only be touched by one person)
The two soaps used in the two variable dishes should be different brands.(Example I use dthe soap from the men’s bathroom(white) and the soap from the womens room)Controls & Variables
