Air Tub Pressure

This is our first official air experiments. My class learned about the six steps by step scientific method when conducting experiments. Yes, the words are difficult to remember but I am confident that day by day they will get the language.

So here I am explaining how steps when doing an experiment. My students began to inquire what are the things in front of them. It was so funny listening to their prediction.

K2: Are we going to cook?
K2: Are we washing the cups?
K2: Can I play with them?

I showed them the red tub, a clear cup, and some newspaper. I told them they will need to use their thinking skills to predict their task. I showed to them that they will put the newspaper in the clear cup and dip in the water. I asked them what they think of the newspaper. Will the paper get wet or not? Most of them said, Yes, it will get wet. While a few said, it won't.

I told them we'll do the experiment and see what will happen.

They were surprise that the paper didn't get wet.

K2: I think I didn't dip the cup enough.
K2: I see there is a white portion here Ms. Jai
K2: Is that the air?

Ms. Jai: Yes. That is the air. There is air pressure every time you try to dip the cup in the water and that prevents the newspaper to get wet.

I couldn't stop them when they said they want to do more.
