1) Carry out an experiment with a glass of water, clearly proving the existence of atmospheric pressure.
Write down the results and conclusions.
If you fill the glass with water, cover it with a sheet of paper and turn it upside down, holding the sheet with your palm, then the water will compress, as air presses on the sheet of paper and presses it against the walls of the glass.
2) Make a homemade barometer according to the description of the textbook.
3) For several days, observe the change in atmospheric pressure (increased, decreased, changed slightly).
Write the results of the observations in the table.
