5.+Method


 * Method:**
 * 1.** Put the ladder on the balcony to get maximum height to drop the object from.
 * 2.** Find the three boxes that have the same surface area and measure the Surface area of the bottom side.
 * 3.** Leave one box 1 whole.
 * 4**. Cut box 2 so the surface area is half of box 1.
 * 5**. Cut box 3 so the surface area is third of box 1.
 * 6**. Cut the box 4 so the surface area is one quarter of box 1.
 * 7**.Measure the height from the top of the ladder on the balcony to the ground.
 * 8**. Fill box 4 with cornflakes and measure the mass of the object.
 * 9**. Drop the box from the same height and use a stopwatch to time how long it takes to drop.
 * 10**. Repeat this three times and take the average speed.
 * 11**. Put cornflake in box 3 until it’s same mass as box 4.
 * 12**. Repeat the step 9 to 10 with box 3.
 * 13**. Put cornflake in box 2 until it’s same mass as box 4.
 * 14**. Repeat the step 9 to 10 with box 2.
 * 15**. Put cornflakes in box 1 until it’s same mass as box 4.
 * 16.** Repeat the step 9 to 10 with box 1.
 * 17**. Average the times for each surface area to make a fair test.
 * 18.** Plot a data in a line graph.
