What’s it about?
Chemically, fats and oils are similar to each other, but their melting points differ. Fats are solid at room temperature whilst oils are liquid at room temperature. Fats and oils contain more energy per given weight than any other food.
People living in very cold climates depend on fatty foods for energy, but fatty foods are also the reason for the many obese people around the world! Let’s test the fat / oil content in some everyday foods with the following science experiment:
Topics covered
Fat, Oil
What will I need?
- BROWN PAPER
- TRAY
- 4x COTTON SWABS
- ICE CREAM
- MAYONNAISE
- YOGURT
- PEANUT BUTTER

How does it work?
Unfortunately, this section is only available in the e-book version of the project.
In this science experiment the fats / oils contained in the food samples travel through the fibres of the brown paper, turning the paper a darker brown colour. Some of the dark stain is only water and will evaporate overnight. The dark spots that spread out the widest after two days contains the highest fat / oil content.
