Title: The Recipe for the Highest Bouncing Super Ball
Name:
Date: November 14, 2013
Question: How much borax is needed from 1g to 5g to produce a super ball with the highest bounce from the height of 1.5m?
Hypothesis: If 2 g of borax is used to make the super ball then it will produce the highest bounce because 2 g will make the appropriate number of bonds without producing a ball that is too soft or too hard to bounce.
Materials:
Paper cup
Beaker
Graduated cylinder
Stir stick
Pencil
Scale
White glue
Water
Safety glasses
Gloves
Ruler
Meter stick
Borax
Masking tape
Borax – Safety note: Borax is toxic and is an irritant to both skin and eyes. Be careful not to inhale the powder or to get it, or the solution, on your skin or in your eyes. If contact is made be sure to rinse area with lots of water.

6. Take your beaker and put it on the scale, set your scale back to zero and take the borax and fill the beaker till you measure 2g.
7. Then take your graduated cylinder and fill it with 4ml of water. Pour the water into the beaker with the 2g of borax.
8. Take your stir stick and mix up the borax and the water till the borax is dissolved completely.
