Science keeping Apple Users 1.1. The importance and `Projects subject. Storage apples. The organizers prepared because it recognizes the problem of buyers and sellers. Since that time, we will have to buy fruit to eat at home or buy to sell. Then waste The Staff Recognize that we should find ways to keep the fruits that we waste so that it can be stored longer edible. In this experiment, the organizing committee can bring apples to be cut into six pieces and then put apples all six pieces are soaked in water, salt and vinegar at least two pieces for a period of 10 minutes. Then the apples are six pieces divided into two groups, refrigerator with freezer bag into a bowl and refrigerate for two days and noticed the objectives : 1. To study the salt water and vinegar. Anything that can extend the life of apples as long as possible. When using the foot and put in the freezer as defined operational life of apples means making Apple has remained the same or making apple is rotten soon premise apps. Apple plated salt water before it can be placed in the refrigerator as long as possible variables 1.4 4.1 storage apples variables - water, salt, vinegar variables. - The condition of the apples in each of the three variables control. - Apples of the same type. The amount of water each The infusion time and keep refrigerated benefits are expected to be : 1. Practice using the scientific process in order to bring to trial 2. applied to everyday life correctly, 3.1. Equipment and chemicals 1. 2. 3. beaker of water, saline 4. 5. 6. Apple vinegar 3.2. Preparation 3.2.1 The process of preparing the three types of water pouring water into a beaker at first about 90 ml. Pour water into two approximately 90 ml beaker. 3. Pour the vinegar into three approximately 90 ml beaker. 3.2.1. Preparation apples 1. Wash apples thoroughly 2. Sliced apples are a 6 piece 3.3 experimental procedure brought apples and cut into six pieces and then put in a beaker. Beaker 2 pieces of 10 minutes to 2 days refrigerated record results Conclusions from the study to extend the life of apples found that ......... 5.2. The discussion of the study results from the water, apples and six pieces soak it in a beaker with water, each a 10-minute results show that Apple has passed the brine ago. You can extend the life of apples to rot slowly as long as possible. Let's come down to the water But Apple has soaked it with vinegar. The rotten Because vinegar is acidic, so the meat bite the apple. It was a rotten apple. Obviously. 5.3 Feedback should measure the amount of water the three species have a certain amount should be cut Apple the same size lead Apple in the freezer to cool it in the same amount.
