The moment Bonkochan came back from school, she said with a great joy, "I won the bronze prize!"

Her summer project was evaluated and she could win the bronze prize.

Congratulations on your great job!

The theme of her project of this summer was "The relationship among water, salt and ice."

Water turns into ice. (Case 1.)

And if you dissolve salt in water, the salted water can turn into ice in a shorter time than just water. (Case 2.)

Bonkochan made a comparison between the time needed in Case 1 and the time needed in Case 2 and studied on the melting point of eace cases and concluded the reason why such differences came out.
