Take some time to click through this site to learn more about cells and their structures. 

Here is another good place to learn about cells. 

Look through each site and then leave me a comment as to which of them you preferred and WHY

If you find any other sites on this topic that you think would help your classmates learn, please include them in the comments too.

Nervous system

neurons from www.images.wellcome.co.uk

Some of the questions we’ll be tackling in the next section of the syllabus (6.5) are:

Do you know what the CNS and PNS are? 

Can you explain what role receptors, sensory neurons, relay neurons, motor neurons and effectors play in conducting nerve impulses?

Can you draw and label a diagram of a motor neuron?

Can you define resting and action potentials?

Can you explain how nerve impulses pass along a neuron?

Can you explain how impulses travel from one neuron to the next?

Read through your textbook pages 240-246 to get a head start on this unit over the break 🙂

And once again, a great presentation from Mr Stephen Taylor in Bandung to help you learn this stuff!

In class we will use this presentation – Nervous System

There are some useful animations here,  here and here that might help you visualize what’s happening.

This week we’ll be getting the microscopes out and you will be making your own slides of different cells.  On the link below you will find the instructions for how to do this.  I suggest you read them before class.  This will save you time in the lesson, and you will be able to make more slides 🙂

Once you have made your slides, you will be expected to draw biological diagrams of what you observe.  The rubric that will be used to assess these drawings is here:

Can you name the parts of a microscope?

Immunology websites

Wednesday, October 14th, 2009

Here are a couple of useful websites to cover topics 6.3 and 11.1 on the immune system.

The Biology Project has problem sets, tutorials, resources and interactive activities.  I particularly like the HIV/AIDS simulation one.

The Cells Alive site has a number of useful links and animations.  Click on the immunology tab on the left hand side and go from there.

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
