Air inside vs Air outside

Students completed an observational report for their science fair. First we used our senses to describe air while we were in the classroom. We concluded that when we are inside, we can not see, hear, taste, feel, or smell air. When we went outside though we could see evidence of air through the wind. We could see the wind moving leaves and trees, we could feel the wind on our skin, we could smell emissions from cars, we could hear rustling leaves on the ground. We did decide that we still could not really taste air though. ​
