The size of the canopy does not affect how quickly the parachute falls to the ground. The results showed that the small canopy (5cm x 5cm) fell to the ground the quickest and the larger canopy (20cm x 20cm) took the longest to fall to the ground. The results of my experiment fail to support my hypothesis. I have learned that the reason the smaller canopy was able to fall quick is because it has a smaller surface area which means that there is less air resistance pushing up on the canopy and slowing it down as it falls to the ground.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
