This week we’ll be looking at the development of the cell theory.  You will need to research the contribution made by each of the following scientists, find a picture of the person or what they made or saw, then use the information to construct a timeline.  Put all that into a powerpoint or prezi presentation.  Done! 

1.      Hans and Zacharias Janssen

2.      Robert Hooke

3.      Anton Leeuwenhoek

4.      Matthias Schleiden

5.      Theodor Schwann

6.      Rudolf Virchow

7.      August Weismann

Here is some more info and the rubric that will be used to assess this activity.  Integrated Science 1 cell theory activity

Our bodies remain healthy despite coming into contact with germs and microbes many times a day.  This is due to the fact that we have a pretty efficient defence system that protects us from disease.  See here for a presentation on this topic.  For Higher Level students, you need to go further, so here is another useful presentation.

You will be required to make notes for yourself and your classmates on some aspect of this topic.  You may choose to create a podcast, slideshow, prezi or simply a set of written notes.  Get creative!  To see your assignment, please click on the following links.

Here is another excellent presentation from the www.sciencevideos.wordpress.com site on the topic of transport.  I recommend you find some time to take a look at it this week. 

We will be doing a heart dissection during the 3rd lesson on this unit.

Here are some great presentations from an IB Biology teacher in Indonesia.  I’m sure he’d appreciate a word of thanks if you find them useful.

Dihybrid crosses, gene linkage and recombination

Polygenic inheritance

Meiosis HL

Chi-squared test

Here is a link to a fantastic presentation on Topic 6.1 (Digestion).  Well worth a look
