What affects the kinetic energy of a trolley? Aim: In this experiment I will be trying to find out the amount of starch that a potato chip has. Pre-Test Pre-test Results Mass start (g) Mass end (g) Mass change (g) Mass change (%) Average mass change (%) 0% A 3.91g 4.37g 0.46g 11.76% 11.20% B 4.14g 3.58g -0.44g -10.63% 20% A 3.97g 2.42g -1.55g -39.04% -32.28% B 3.88g 2.89g -0.99g -25.52% 40% A 3.92g 2.29g -1.63g -41.58% -44.29% B 4.17g 2.21g -1.96g -47.00% 60% A 4.08g 1.69g -2.39g -58.58% -58.08 B 4.05g 1.72g -2.33g -57.53% 80% A 4.17g 1.39g -2.78g -66.67% -63.33% B 4.00g 1.60g -2.40g -60.00% Plan: 1.) Cut 10 potato chips to a size, around 4cm long. Then weigh each potato chip and put them into pairs and tie a piece of string around on potato chip in each pair but making sure the string isn't tied too tight or too loosely around the chip. 2.) Now make five sugar concentrations and make one sugar solution at each different concentration: 0% sugar, 20% sugar, 40% sugar, 60% sugar and 80% sugar. 3.) Now place one pair of potato chips into each sugar solution. 4.) Leave the potato chips in the sugar solution for 24 hours. 5.) After 24 hours, re-weigh each potato chip and record it's new weight. 6.) Using the weights...
