Fats Facts Fun! | Science Fair Projects | STEM Projects
Ever wondered what makes fats from plants and animals different? Find out with this simple experiment!


The hypothesis is that fats from plants and animals have both similarities and differences.

Method & Materials

You will compare butter and vegetable oil by observing them in different ways.
You will need butter, vegetable oil, a brown paper bag, wax paper, scissors, water, masking tape, a plastic straw, zip-closing plastic bags, clear plastic cups, cotton swabs, a bowl, and a ballpoint pen.


The experiment showed that fats from plants and animals have both similarities and differences. The butter and oil soaked through the brown paper bag, felt greasy, and did not dissolve in water. The milk fat in the butter had a structure that allowed it to be shaken until it became solid, while the oil could not be melted and resolidified.

Why do this project?

This science project is interesting and unique because it allows students to explore the differences between plant and animal fats in a fun and engaging way.

Also Consider

Experiment variations to consider include comparing different types of plant fats, such as corn oil, olive oil, and peanut oil, or comparing fats to other substances, such as cheese, soap, and beeswax.
