II. Refer to the given situation below then answer what is being asked. (5pts.)
You are the monitor of your class for the day. After sweeping the floor, you collected the
following waste materials: Fruit peels, crumpled papers, plastic bottles, leftover foods fell on the

c. Clay is plastic and tenacious when moist and becomes permanently hard when baked or
fired hence, it was widely used in early civilizations for making pots, plates, sculptures, and
building materials. If you will make a cooking pot made of clay, which method do you think
is better to use, hammering or molding? Explain your answer.

d. Garment steamer is a handheld appliance with a hose and a wand which is widely used
nowadays in removing wrinkles on clothes. It is different from iron that has heated metal
surface & uses ironing board to flatten wrinkles from your clothes. Unlike iron, a garment
steamer only requires you to hold them a small distance from the fabric but it relies on
vapor spray which relaxes the fibers of your clothes so that they smooth out on their own.
If you are to choose which appliance is better to use in removing the wrinkles of your
clothes, is it the traditional iron or the garment steamer? Why do you say so?
