Here is the link to that powerpoint we used in class today. If you like his work, I’m sure Mr. Taylor would appreciate you letting him know.  Get ready for dissection tomorrow!

Here is another excellent presentation from the 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.

Assessment coming up!

Thursday, August 20th, 2009

During the first week of SEPTEMBER you can expect to be given an assessment on what we have covered so far in G9 Integrated Science.  That means all the stuff on variables, units, significant figures, errors, science apparatus.  We’ll talk more in class about this but here is a link to some powerpoints you might find useful.   Click through the first few introductory slides to get to the good stuff 🙂

Lab report rubric

Thursday, August 20th, 2009

For this first lab report on Murphy’s law, we are taking it nice and slow, and working together in class for much of the time.  In the future, you will be expected to write up the experiments more independently.  Here is the rubric, or something very similar,  that will be used to assess your work.  Integrated Science Rubric for assessing Lab Investigations.

Our next topic will be a loooooong one – Human Physiology will last the rest of the semester.  We’ll start with the core material, which is Topic 6.  You can download the syllabus guide here: Topic 6 – syllabus outline

The first section is on the digestive system.  You can get a head start by reading your textbook – Chapter 19.  We’ll cover the theory first, and end the week by dissecting a complete digestive system.  When will you have the chance to stick your hand inside a goat’s stomach again, or simulate peristalsis on some real intestines?

Deadlines, deadlines

You are in the process of writing up a lab report on demonstrating absorption and digestionBlock B students have already had a lesson on this and are due to submit their final version to me, either electronically or on paper, by THURSDAY 27th AUGUSTBlock F students have until FRIDAY 28th AUGUST (We will spend next Tuesday on this so don’t panic!).  Please make sure you see me during tutorials if you need help.  Our next unit will be on the transport system (the heart, blood and blood vessels), so read your textbook if you want to get a head start on this.

Here is a link to a resource with some good information that might help with the digestion homework you are currently working on.  Click on the various links about digestion of different macromolecules.

Here is the lab sheet for the Murphy’s law toast drop.  Murphy’s Law G9 lab  Print a copy for yourselves if you would like to have a paper version. 

Don’t panic – there will be lots of help with the data collection and analysis part.  Don’t forget to bring in any “extra” spreads that you plan to test.  This should be fun!

Good review presentations

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
