Scientific experiments answer questions. When Dr. Philip Tierno conducted his experiment on the pillows, what question was he trying to answer?

I know what video you're talking about, I watched it.

He was trying to answer where the kids were getting their allergies from, the mother continued cleaning the house nonstop, and they still got the allergies. He thought they might be getting the allergies from the pillows they slept on, and, he was right.

Hope this helped!

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
