All Systems GO!

April 5, 2012

So, here we are at the end of term 1. A lot has been covered in class this term – we started with some scientific processes, but quickly moved into body systems and interactions between systems, and have now transferred over to things that affect the whole body (so far we’ve looked at E-M radiation). We have quite a bit to cover yet, but before we go on, let’s ensure that everyone is up to date.

Notice that I wrote that “A lot has been covered in class” and not “we have done a lot in class”.

That’s mainly because I haven’t seen much work from many of you – something that you need to address urgently, because from the first day of next term, students who have not completed the work will be required to attend half-lunch detentions and JWOP to finish that work.

Here is a list of the tasks that must be completed:

Beating the System

February 16, 2012

So we are studying body systems, particularly the “responding” systems – that means the systems which control how we react to what happens around us. You may think you control your body reactions, but it is simple to prove that you don’t – just think of the last time you heard a loud noise or saw an unexpected bright flash of light. You reacted without planning to – a reflex reaction.

The two main systems we will focus on are called the Nervous system and the Endocrine system. In today’s lesson, we will be learning more about the Nervous System, particularly how it works; how it helps you respond to what happens in the world around you.

The nervous system consists two main parts – the Central Nervous System (basically the brain and spinal cord) and the Peripheral Nervous System (the nerves which connect to the rest of the body).
