Type

Chemistry

Objective

In this experiment, we will find out whether different types of oil mix or stack on top of one another.

Research Questions

  • Can you think of different ways that oil is used?

Introduction

It is widely known that solids have different weights, but liquids also have different weights as well. Oil is viscous in consistency and slippery in texture. There are many different kinds of oil. Some are edible (like peanut or coin oil) and some are used for lubrication in personal and industrial applications.

Materials

  • Peanut oil
  • Canola oil
  • Corn oil
  • Olive oil
  • Baby oil
  • A large, deep clear glass or plastic container
  • A large spoon

Experimental Procedure

  1. In the large, deep clear container pour about one cup of each kind of oil inside.
  2. Observe if it “stacks” or looks like an undistinguished “blob”.
  3. Try mixing the oil with a large spoon and see if it “settles” out or stays mixed.
  4. Record your results.

Terms/Concepts
