I have done a project, showcases that air has weight. I have tied two balloons on each end of the ruler. The balloon which has air has more weight. The mechanism shown here is known as weighing scale and was used in olden days for measuring weight. It was banned because shopkeepers were putting extra weight under it and shoppers had to pay extra money for it without knowing.

I learned that air pressure holds the cardboard in place when I turned the cup upside down. The air inside the cup kept the cardboard from falling. The challenge was making sure the air didn’t escape. I used persistence because I kept trying different ways to make the experiment work.

Thinking from first principal bases.                                                           Water stays in a glass when it's upside down because of atmospheric pressure, which is the force exerted by the air around us pushing upwards on the water, counteracting the downward pull of gravity and effectively holding the water in place within the glass; essentially, the air pressure pushing up is greater than the weight of the water pushing down.

HOM- Thinking Flexible.   In this activity I took a glass and filled it with water then I covered the mouth of the glass with a paper and then I hold the paper in place and inverted the glass slowly and safely, then I removed my hand from the paper then I noticed the paper sticks to the glass and water stays in the glass. It doesn't fall from the inverted glass. This concludes that air exerts Pressure on the paper from below to keep the paper in place. Here the pressure exerted by air upwards is more than the weight exerted by water downwards. Thankyou.

The water did not flow from the plastic cup because During this experiment, the air pushing up from underneath the paper is strong enough to overcome the weight of the water pushing down on the paper. Due to the air pressure pushing up on the card, the card will stay on the glass, so the water will not spill out. habit of mind used is gathering Data through all scenes.

The water didn't fall because when I put the paper on the glass filled with water then I upside-down I was surprised that the water didn't fall so the reason behind the experiment is that before I put the paper some water was not there was the space in the glass was the air when I put the paper on the glass the air was blocked the air was up and the water was down so the air is pulling from up and down also that's why the water was not falling  down. I responded with with wonderment and awe.

The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add baking powder and vinegar it makes together and starts to react with each other and it makes gas, carbon dioxide. bubbles of Carbondioxide starts coming on top .Gas or air, is lighter than water so it floats to the top. The air bubbles bring some colored water with them to the top. When the air comes out of the colored water blob, the water gets heavy again and sinks. It does this over and over again until the chemical reaction stops.
