Air Has Mass - Science Lab

Air Has Mass and takes up space

Hi! I'm just sharing about our latest science lab. To show that air has mass, we filled a bucket with water (half full), stuffed some tissue into the bases of  plastic cups, then held each cup by their bases and slowly immersed them (upside-down) into the water. We made sure not to lean the cups as they we being immersed. For the final step, we slowly pulled out the cups while keeping them in the upside-down position. With our other hands (which were dry) we reach into the cups to test the condition of the tissue. Can you guess if the tissue was wet or dry?

Air Has Mass

There are other experiments that you can do to show that air has mass. A simple one that I did with some younger students was to fill a balloon with water and fill another with air. I would ask the students to describe what is in each balloon. They would usually say that the second is empty. So I would challenge them to gently squeeze down the second balloon because since it is 'empty' then the balloon doesn't have to be so big. Then they realize that it has air and that they cannot make the air disappear. So then we talk about mass.

What kind of experiments do you do with your students to prove that air has mass or takes up space?

About Me

My photo
As a Caribbean primary school teacher, I share my unique classroom with the world through this blog. Readers step into my class through the pictures, articles and classroom samples of games and lessons used in my class. I have been teaching since 2005 at the std. 4 primary level in Trinidad and Tobago. I am particularly interested in sharing my own personal lesson plans, tests and activities. Teachers need to share ideas and support each other because in doing so, we help to educate our students and develop ourselves as teachers. Technology is ever evolving and we as teachers should get on board with it, collaborate and keep up to date with this new age that we live in. Our students belong to this technological era and we must embrace opportunities to learn from each other in this global community. I also love to express my creativity in the classroom. I am a bit of a craftster . So I'm always cutting, gluing or making something... a game, a chart, a learning center, etc. So, teachers and parents, feel free to stop by and see what's new at Nyla's Crafty Teaching!
