Experiments: To test for fat.
Materials:
Method:You will need:
A piece of brown paper,
a sample of food – butter.
1. We rubbed our food sample
(butter) with brown paper.
2. Then we waited and observed the effect that the food had on the brown paper.
3. We recorded the results.
Result:
The butter stained the brown paper and the stain was see-through – this type of stain on the brown paper is called a translucent stain. The stain would not come off.
Conclusion:
1. If there is a permanent
translucent stain on the brown paper then fat is present.
2. If there is no stain or a stain that dries away then there is no fat present.
