Add-on optional assignment:

Class,

Share with me ay words of wisdom you have learned in your time.  You can write them on the assignment you turn into me.  I will take the stuff you share and post it on my blog.

Here's two of my favorites:
Best piece of advice I ever got:  never lose your sense of humor
Favorite saying:  A ship is safest at bay, but that is not what ships are made for.

Last assignment!!!!!

Choose one of the following questions and turn in your thoughtful, original answer by your last day.

This will count as your final, which is awesome because its easy!

Question 1:  If earth's axis spun perfectly up and down, how would life be different?  (explain 5 biological examples)

Question 2:  If there were no moon, how would life on our planet been different? (explain 5 biological examples)

Question 3:  If life were discovered on another planet in another solar system, most of what we've learned would be useless. What ideas would still apply? (Explain three biological examples)

Once you've done this, congratulations!  You are now done with IB Biology

Happy Biology weekend!!!

Hello all,

Our goals for this weekend are to learn about the heart (statements 6.2.1 to 6.2.4)
.

Here's a link to the animation I used in class about muscle contraction.  I hope you find it to be a useful review.
