REMINDER
Block B will have their test on Topics 6.1 Digestion and 6.2 Transport System on THURSDAY 17th SEPTEMBER. Block F will have theirs on WEDNESDAY 16th SEPTEMBER. Usual format – part multiple choice, part short answers – all from past IB papers.
COME TO TUTORIALS if you need help with anything.
Here is the instruction sheet for this lab, along with the rubric. Lab – Demonstrating Absorption You will be assessed on conclusion and evaluation only for this lab. You need to submit the following by Tues 15th Sept – either soft or hard copy.
A copy of the lab sheet. Your hypothesis, including justification. Your data tables. Your conclusion and evaluation.
Describe the route taken by a ham, cheese and lettuce sandwich through the human digestive system, explaining what happens to each part of the sandwich as it passes through each region of the digestive tract. [20 marks]
Complete and correct route given [4]
Digestion of bread [4]
Digestion of ham [4]
Digestion of cheese [4]

Bibliography in MLA format [2]
You will have class time on Tuesday 1st September for this, and must submit it no later than Thursday 3rd September. Here is a link you might find useful.
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!

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?
You are in the process of writing up a lab report on demonstrating absorption and digestion. Block 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 AUGUST. Block 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.
