Lesson details

Key learning points

  1. Fats in food, absorbed by paper, are easily visible and make it easy to identify which foods contain fats.
  2. The size of greasy stains from food on paper can be observed and/or measured and compared.
  3. Scientists often evaluate a completed investigation and suggest improvements.
  4. The results of a scientific investigation can be compared to secondary sources that already exist.

Keywords

  • Fat - Fat is a nutrient found in foods such as butter and cheese. Only small amounts are needed as part of a healthy diet.

  • Greasy - Something that is greasy is covered with or contains fats and oils.

  • Evaluate - To evaluate is to think about what you did and suggest any changes or improvements.

Common misconception

Pupils may think that foods containing fats are 'bad' for humans and we should not eat them.

Emphasise to pupils that humans need some fat as part of a balanced diet and it is a diet that is very high in fat that is not healthy for humans. The foods themselves are ok to eat as part of a balanced diet.

Choose a method for counting the squares that contain grease. For example, counting all of the squares that contain any grease or only counting the squares that are fully covered in grease. Whatever method you choose, be consistent.
