The Best Homeschool Science Air Pressure Experiments
Although we believe that air is weightless, the air has weight. This air is constantly provided the power on our skin. We can not feel this weight, because the air on all sides, and, therefore, equal weight has on our skin from all sides. Air Force has on an object is called air pressure. This pressure can be demonstrated using simple Homeschool scientific experiments. Air exerts pressure 14,7 PSI (pounds per square inch) at the facility, including our skin. This air pressure, that a huge 1inch x 1 inch vertical column of air in Earth’s atmosphere, puts on you and me, or any other object at sea level. This is called atmospheric pressure. I will show, the fact that air has weight in our first experiment Homeschool Science below.
The inverted water glass trick: fill one-third cup of water. Place a piece of cardboard over the mouth of the glass. Doing a piece of cardboard to place his left hand, invert the glass. Now remove the left hand, holding the glass upside down on the right side. What’s happening? Surprisingly, a piece of cardboard (and water) remains in place. How did this happen? This is because the atmospheric air pressure 14,7 PSI (remember?), Which pushes up cardboard larger than the combined weight of the water and the air inside the glass, which leads to an increase of cardboard down. This is proof that the air that fills our atmosphere has weight.
Why do things move? As I said earlier, this pressure is equal all around us on all sides. After this change in atmospheric pressure on either side, the object will move. The mystical sounds, is not it? This phenomenon causes the winds. When there is a big difference between the pressure in two places, due to the tornado. Kites to move higher because of this pressure. The plane rises from the runway, setting the air pressure in use. The difference in pressure makes things move, and it can be demonstrated through our second experiment Homeschool Science below.
Fountain bottle: Fill a plastic bottle of carbonated water with half the water. Now insert a hard plastic straw into the water and seal the bottle mouth with clay. Blow hard through the straw in the bottle and the displacement of the bottle. What’s happening? Water runs out of straw, like a fountain. How did this happen? When you blew air through a straw, you increase air pressure inside the bottle. Since the pressure inside the bottle increases, it has such a pressure on the water, pushing it through a straw.
