• Class Expectations– You can show respect by…

• Listening when the teacher or others are talking.– One speaker at a time, please raise your hand.

• Please no cross-room conversations during work time…aka – shout outs.

– You can be responsible by…• Staying organized and avoiding distraction.• Staying focused on task completion.

– You can make good choices by…• Attending class regularly • Doing your best and never giving up.

– Be Safe!• First, last, and always.

• Answer : It has a lot to do with our next area of focus.


• Research Opportunity! There are many theories about why and how we age. – Who would like to tackle this question and report

back to the class tomorrow?

• Video (Optional)! Time Lapse of aging. – One picture everyday for six years.– A neat video for the end of class. (6 min)– http://www.youtube.com/watch?v=6B26asyGKDo

• Important Note - Although mitosis will be discussed as different stages, the process is generally continuous.


• Before we begin, we must learn about chromosomes.


• Humans have 46 chromosomes in their cells.– Not sex cells to be discussed later during

meiosis.
