DESCRIPTION
Done by Earth group, Mohamed bin AbdulAziz Almana Independent secondary school for boys Food packaging is packaging for food. A package provides protection, tampering resistance, and special physical, chemical, or biological needs. The sodium benzoate used in refrigerators plastic cans to increase the duration of food preservation thus increase food shelf life

Objective
Comparison between natural materials and industrial materials
Which is better with liquids, whichever is best with the material is liquid
Activity4(Throwing eggs)
We bring in 2 eggs and 2 of the bags and put the bags in one of the natural material with the eggs and put the egg sac with other industrial material and close the bag and each bag we throw out that broken eggs and record every time you throw away

Objective
Know the difference between power tomatoes coated and non-coated taking into account the weight
Activity5(Throwing tomatoes)
We bring in 2 of the tomatoes we encapsulates 1 and the survival of the afterlife without packaging
We weight of packaging We then weight of tomatoes and use this law to
know the extent of damage to the net and packaging on the environment
Then we threw tomatoes from a height of 50 then 100sm then 150 ..... etc. to the crash tomatoes and record results

Conclusion The tomatoes coated withstand more than non-coated
Activity6(Temperature materials with changing times) Objective
Knowledge of the extent of temperature change with the change of time and whichever is best to keep the temperature has to be an insulator or without insulator
Procedure Bring 4 cups empty
And 2 thermometer
We work from a hole in the 2 cups
Put hot water in cups that do not have holes and put the tin on 2 of cups, one of them by the hole and the other does not and put plaster and a thermometer and we begin recording temperatures with the passage of time either cups hereafter we put hot water and paste cups and put the thermometer and we begin to register temperatures

CONCLUSION
The materials that have been packaged heat transmitted them less quickly than non-
coated
We are a group mba_earth 8 We participants
in the contest AL-Bairaq and scientific Haya
contest affiliated with the University of Qatar
and this year's competition for food packaging
Final Project:Smart Plastic cans
for leftovers
Introduction and Rationale:
We have noticed that the food begins to decay after the period we wanted to increase the duration cooled validityThe project has a great benefit to the Qatari society, it reduces the money in consumer consumption Purchase of foodWhat attracted us to the project that the materials simple and useful and availableThe project has no harm to the environment also benefited from training with the team AL-Bairaq
Aim of the work (objectives)
Our goal is to find a way to increase food validity after being left in plastic cans in the fridge
Hypothesis: (الفرضية)
Assume that the materials needed are available and cheap and not harmful to the environment
Methods and Materials
Sodium benzoate (so we did not find it using the lemon because it contains sodium benzoate)
Plastic Boxes
Photos
Results:
The sodium benzoate used in refrigerators plastic cans to increase the duration of food preservation thus increase food shelf life

Recommendations:
We would like to recommend that the research on the project will continue to develop and improve
Conclusions
The sodium benzoate increases food preservation thus we can use it in the manufacture of plastic cans
