"Discovering My Toys" (DGW, page 33-39)

There is four lessons that students studying in this week.
    They figure out how water makes water toy moving and float, and the air is what makes the ball, and balloon became fun toys. The balloon can float because of the wind. Remember, wind is moving air!
    The students also do their fun experiment: "Make a balloon jet" base on page 38. They use a balloon from mr. Wesly, and they blow up the balloon. The balloon was fulled with air. When the students let go, the air rushed out. It pushed the balloon the opposite way. A jet plane works this way too, but it uses very hot gasses.
