### Science Fair Project Ideas For Kids, Middle & High School Students

What happens to the air pace via the tube the narrower (flatter) it becomes? Comment on the obvious trade off between fan power and the level of cooling because of a narrower or wider tube hole. The idea here is that you just fill the container with chilly ice-water after which blow air by way of the tube using a fan. The air exits the tube cooler than it was going in, as a result of warmth exchange between the cold ice-water and the air flowing by way of the tube. On the end of the tube the place the air enters you have to make a sort of funnel which fits around the fan and channels the air into and thru the tube.

Due to the nature of the physics, it will trigger the floor of the plaster-of-paris to form a parabolic shape. Upon hardening, the plaster will retain … Read More
