, keeping the apple
1.1 members origin and significance
."Project of storage of apples. Established since the party organizer can spot problems of buyers and sellers. Since that time we will have to buy some fruit to eat at home or buy to sell, then left, leaving,The spot that we should find ways to collect the fruits we left abandoned in order to be able to eat it for a long time. In this experiment, the organizer, the apple to operate into 6 piece and the apple, both 6 pieces.Salt and vinegar as 2 pieces for a period of 10 minutes the whole apple 6 pieces. The group is divided into 2 bag in the fridge to put a refrigerator bowl 2 day and observe the
.
1 purpose. To study between water, salt water and vinegar. Nothing can extend the life of the apple as long as possible. When the infusion rate, and the time in the fridge too
the definition workshop
.Extend the life of the apple, means to make apple has same or making apple rot early
Apple hypothesis coating saline before water soak in the refrigerator can be as long as possible
.
4 1.4 variables.1 keeping Apple
variables - water, brine, vinegar
variables. The condition of each kind of apple - water three
control variables - the same kind of apple water content each kind of freezing time and stored in the cold
.
.Expected benefits
1. The practice of using scientific methods in various aspects.
2. The test applied to the daily life ลองไป correctly

.Conclusion
. The extension of the apple the results showed that.........
5.2 discussion the
.The result of the apple juice, both 6 pieces. To soak in a beaker of water each kind, for 10 minutes. The results showed that Apple has soaked brine. Can extend the life of the apple to rot slowly as long as possible.But Apple has soaked in vinegar to spoilage. Due to high acidity, therefore the texture bite apple. Making apple spoilage. Obviously.
5.3 suggestions should measure the amount of water and 3 types have certain quantity
should apple slices, so only the apple in the fridge
to be cold in rate
