SAC+1-+preparation+materials

For the first SAC you will be creating a model/ mock cell using cellulose bags. These bags act like membranes, in that they allow some materials to pass through but not others.

Like cells, these models are 'selectively permeable'.

You will be testing starch and glucose levels inside and outside the bags over a period of time and determine the movement (if any) of

1. Water 2. Starch 3. Glucose

As you carry out the activity you will record detailed observations and measurments (tables will be supplied). You will answer some questions during the activity as you make observations. You will answer more detailed questions at the end of the session to show deeper understanding of what is happening and how it is related to cells.

To ensure that you complete the activity and demonstrate your understanding, you WILL NOT need to write a complete report.

The documents below will help you prepare: They include - an overview of the concepts you need to understand. - a glossary - performance descriptors from VCAA

This is for SAC 1 (not sac 2)
