The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

Shell - less egg is placed into a beaker of corn syrup‚ will there be any water going into or out of the egg and if the shell - less egg is placed in a beaker of distilled water will be any net flow of water going into or out of the egg. Hypothesis: If a shell - less egg is placed into a beaker of corn syrup solution‚ then there will be a net flow of water going into the egg because the water molecules will be small enough to pass through the membrane of the egg. If a shell - less egg is placed
