Grade 4 Science Experiment 3 - "How to make Natural Plastic using Household Items"
OR
Purpose:
The purpose of this science fair project is to create natural plastic using everyday household items. We use plastic in our lives everyday, but this plastic is synthetically made. In the past, plastic was created from household objects such as plants and the fat of animals. Synthetic plastic of today does not breakdown or deteriorate very easily. This gives the plastic we use today its durability and long life. However, natural plastic created in the past tends to breakdown more easily.
Note: Adult supervision is required for this science fair project.
Hypothesis:
The hardening properties of animal fats, proteins, and minerals allow you to create natural plastic.
Variables:
Type of plastic - natural versus synthetic plastic
Materials Needed:
-
- Four ounces of whole milk
- One teaspoon of vinegar
- Soil
- Spoon
- Two glass jars
- Small plastic object
- Two clay flower pots
- Wax paper
- Camera
- Pencil
