Making a model gut

7N are making a model gut today in Science. 

First wet your visking tubing

Then tie a knot in the bottom of the tube

Now pour in 8ml of starch solution and 8ml of glucose solution. 

Now tie the open end of the visking tube

Then wash the tied tube incase of spillages

Then place the tube in a boiling tube of water. 

Label the tube then wait. 

Tomorrow we are going to test the water inside and outside the tubing to see which chemicals have passed through the visking tubing wall. 

We have made our prediction - have you?

Check tomorrow to see if you are correct.
