DO NOW

• Complete pre-test• Put your Lab Report on desk for me to collect

ANNOUNCEMENTS

• Tests have been graded and added to Powerschool• Most folks have done well! Congratulations!!• Will be conducting Peer Review of your lab reports this morning.

PEER REVIEW

• You will have 15 minutes to review the lab report.

• Using the green rubric, carefully review each portion of their report and score them as you think.

• Be honest – the more helpful comments you can give will help them write a better report.

• Return the report to them with the rubric.

• Final lab report is due tomorrow.

IS IT MADE OF MOLECULES?

• Complete the worksheet on your own for the next 5 minutes.• When the alarm rings, turn to the person behind you and discuss

what you determined was and was not made of molecules. Discuss the rule you used to make your determination.• Provide 2 pieces of evidence you used to make your determination

• Be prepared to discuss your rule with the class.

LEVELS OF ORGANIZATIONLevel Description Example

1. Atom Smallest unit of matter with distinct properties Carbon

2. Molecule Bonding of two or more atoms together Carbohydrate, Water

3. Organelle Structure inside cells made of multiple atoms and molecules that performs specific tasks

Mitochondria, Nucleus

4. Cell Smallest unit that can carry out all the properties of life Muscle Cell

5. Tissue Group of cells bound together to complete specific task Muscle Tissue

6. Organ Made of varying types of tissue to fulfill function Heart

7. Organ System Multiple organs working together to function as a system Circulatory System

8. Organism Multiple organ systems working together to form a functioning organism.

ORGANIC MOLECULES

• Any molecule that has a Carbon atom• Life depends on molecules may include a variety of other

atoms, particularly Hydrogen, Oxygen, Nitrogen, Phosphorous, and Sulfur in addition to Carbon.
