Ping pong ball experiment (Science)

The purpose of this blog post that I am making is to demonstrate the scientific method, 

of our ping-pong ball experiment in science this week.

Recently in science, we had been using our SciPad, we had to fill out a page that was needed for our experiment once we had finished that page we waited for the next time we had science to do the test.

The page we did before the experiment included for us to do an Aim, Hypothesis and Method.

Aim -To find out how high a ping-pong ball can bounce after being dropped

Hypothesis - I think the ball will bounce a bit over 50

Method - Frist get out your equipment (Pole, Ball and ruler) then once you got your equipment and set it up, then hold the ball from the top of the pole with a ruler next to the pole then drop the ball and watch it bounce. (You take that test 3 times for each length so like 40 cm, you would put it on 40cm and do 3 tests on the 40cm before moving it up to 60 or 50 and doing the same thing)

After you've got your result you make a graph out of it.

After we had done that we waited the next day for our test, we did exactly what it said above and after that, we did our graph and the page next to the graph which included our Discussion as to what went right or wrong. and Conclusion as to say yes or no to if my hypothesis was correct and our Evaluation to see if it was a bad test meaning it wasn't right.

Discussion - When we dropped the ball at 50cm our result was 34,31,33 and though I thought it would be in the 40's I sadly don't know why it got below 40 maybe cause of the drop?

Conclusion - No it didn't because even at 50cm it did not go over 50, maybe I should have done 70cm for our last and not 50 and maybe then it would have gotten over 50

Evaluation - There was a 13 within the 20's when it should be within 20

(Our graph was a single line for those who want to know)
