Advice for your Science Midterm:
You will have your science midterm during class on Wednesday January 16, 2013. The midterm will
count as a test grade for marking period 2. The midterm will be made up of approximately 50 multiple
choice questions from the units you’ve already been tested on (microscope, viruses, protists, bacteria,
and fungi). It will also include the articles you have read from your lab books. These are located on
school wires.
The units and lessons include:
The Diversity of Living Things: Unit 1, Lessons 1 and 5; Unit 2, Lesson 1 and 2
The Human Body: unit 2; Lesson 1and Lesson 2

Essential Questions:
What are Living things?
How are Organisms Classified?
What are microorganisms?
What are Protists and Fungi
What causes diseases?
How does your body’s defense mechanism work?
Levels of Classification from broadest to most specific:
Kingdom -> Phylum -> Class -> Order -> Family -> Genus -> Species
The mnemonic: Kings play checkers on funny green squares!
Remember to write the genus and species names correctly.
For example: Homo sapien
The first letter of the genus name is capitalized, while all the letters in the species
name are lower case. Both genus and species names are in italics when typing, and
underlined if hand written.
