-The proportions of sodium borate and glue matter because the amount of them effect each other. You can use the same amount of glue but different amount of solution each time (or the other way around), the results of texture and how long the ball takes shape varies, the results are never the same, unless you use the same proportions each time.
-I determined the best proportions by changing one variable first which was the amount of glue, observing more or less glue impacted the bounce and shape of the ball. After I saw that testing different amounts of glue I saw that less is more, less had a greater shape and bounce. After I used the same amount of glue that made the ball better I changed the amount of solution to determine if less or more solution had more significance over another. My method is important because it's important when looking for a cause and effect in an experiment to keep track of the different changes of variables and how they impact the ball. Also to determine what can be done to improve.
