Introduction

Biodegradable materials : is a substance that degrades into smaller

nontoxic parts that are returned to environment and may be reused by

organisms.

Activity 1comparing packing materials.

Part :1We compare between white Peanut and Green peanut.Result: the white peanut degraded in water but the green peanut Didn’t degrade.White peanut is biodegradable because it isMade of cornstarch.Green peanut is not biodegradable because it is made of polysterene.

Activity 1comparing packing materials.

Part:21 -bag with biodegradable packing peanut with an egg in the

middle2 -bag with non-biodegradable packing peanut with an egg in

the middle3 -throw them at ground and see which egg breaks.

Resultthe egg in the bag with biodegradable brokethe egg in the bag with non-biodegradable didn’t break.

Activity 2Hunting for biodegradable materials

Non-Biodegradable Materials

Biodegradable Materials

Materials that takes Long time to decompose or

may Never decompose

In landfill

Are objects thatDegradable by nature

Ex: cans and plastic bag Ex: fruits and vegetables

Activity 3

processing biodegradable material andComparing their mechanical properties.

Products we need:Gelatin capsule , 20% , 10% , 5%

10 ml HCL beakersHot plate

Design Project Designing a medicine release capsules

We design a medicineCapsule

Using colored CaCl2And we put it in the water theNext day it degradable in the

water

Our product ideaanti humidity fragranced capsules

Is an anti humidity fragranced capsules made of natural materials

to be placed in drawers and wardrobes.

It is made of natural materials and able to absorb humidity due to the

presence of salt and gives a nice smell.

Conclusions

We learned a lot of new things about BIODEGRADABLE but overall we had a lot of fun and we experienced a lot of new things and we had fun through the way and we hope we continue on with knowledge.
