Will be starting class at 9.30am today. That’s about 15 min from now.

We will go through some questions from our paper last week using MSN- use my email to find me.

UPDATE:

Well, it seems that nobody is around. So I will call it a night.

===============

Ok, don’t know if this works but let’s give it a shot. The test will be from 9pm to 9.15pm.  Join us if you are able to.

There are quite a few systems you need to know. If you can’t go through all of them below, at least cover digestive and respiratory system first.

Digestive System

Skeletal & Muscular Systems

Respiratory System

Circulatory System

Below are some concepts maps to get you started. Click on each one to open them in their own window.

If they are too small for your screen, hover around the bottom right corner until you get the “Expand to regular size” button. Click on it to view each concept map at their actual size.

Alternatively, you can print them out and add your own notes to them. Whatever it is, keep reviewing your own science notes. Makes your revision easier and much more effective.

Remember doing notes is only the start. You need to constantly review what you have already learnt.

In case you missed out what is to be done, here is the problem and questions again.

Problem:
Lynn wanted to buy a new plastic drink bottle. There were only black and white ones in the shop and she wondered which one to get. She thought that a white one would be best as it would keep her drinks cooler during the hot days and her soup hot during the cold days.

You are given:
- Black plastic bottle
- White plastic bottle
- Ice water
- Thermometer
- Stopwatch
