Today we looked at the advantages and disadvantages of sexual and asexual reproduction, and then learned about the female reproductive system in humans. The handout should be filled out using chapter 4.2.

You also got a progress report that shows your grade thus far, and any missing assignments. Please ensure all missing work is turned in ASAP!

Final exam is next Thursday – June 21 – morning.

Mitosis lab – we looked at plant and animal cells undergoing mitosis. You should have seen all of the ‘phases’! Lab booklet due by Friday at the latest

Cut and paste mitosis – practice putting it all in order. Due my Friday at the latest.

Intro to reproduction.. sexual (offspring are different than their parents) and asexual (offspring are genetically identical to their parent).

We will have a short quiz on Friday at the beginning of class on organelles, DNA, and mitosis.

 

Friday June 1 – Science 9

Chapter 2.3 questions due today (#2, 4-11)

Poster gallery presentation is MONDAY.

Today we leapt into the world of cell division as we learned about mitosis. IF YOU MISSED TODAY or just want a refresher PLEASE WATCH THIS VIDEO: https://www.youtube.com/watch?v=f-ldPgEfAHI

We then copied our own notes about mitosis, and you are to read chapter 2.4 in your textbook.

I handed out the unit test outline and review. Review is due TUESDAY. The unit test is also Tuesday so please use the review to help you study.

Wed May 30

Thanks for the great field trip today! We cleared 80 square meters of invasive plants – well done grade 9s!
