Food Fat Test Kitchen Science Experiment
In this fun and easy kitchen science experiment for kids, we’re going to test and see which food contain fat.
- A sheet of white printer paper
- Potato chip
- Peanut butter
- Draw six circles on the piece of paper.
- Label each circle with the name of the food you will be testing.
- Rub a tiny bit of food on each circle.
- Allow to dry for thirty minutes.
- Examine each circle. Some will be dry and some will be greasy. The greasy spots are residue from fats in the foods.
How it Works:
Fats in the foods produce grease spots because fats are nonvolatile. Nonvolatile means that fats have a very high boiling point and do not evaporate easily. In contrast to water, fats that get absorbed by paper cannot get enough heat to evaporate at room temperature. These fats absorbed by the paper are easily visible and make it easy to identify which foods contain fats.
Make This A Science Project:
Collect a large variety of food samples and hypothesize which ones may or may not contain fats and then use the food fat test to determine the results.
