Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

Eye Donation Do you know that we can light the life of a blind person by donating our eyes after our death? In India‚ we have an estimated 4.6 million people with corneal blindness that is curable through corneal transplantation made possible by eye donation. More than 90% of the corneal transplantation is carried out successfully and helps restore vision in people with corneal blindness. Corneal transplantation in infants born with cloudy cornea can make a big difference to their lives.

The human eye is an organ which reacts to light for several purposes. As a conscious sense organ‚ the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors.[1] In common with the eyes of other mammals‚ the human eye’s non-image-forming photosensitive ganglion cells in the retina receive the light signals which affect adjustment of the size

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical
