Science Experiment

EQUIPMENT: A TENNIS BALL, METER RULER AND A CLAMP.

AIM: MAKE A BRIEF STATEMENT OF THE PURPOSE OF YOUR INVESTIGATION.

IN THIS EXPERIMENT, I AM TO WATCH THE HEIGHT A BALL IS BOUNCED FROM AND HOW HIGH THE FIRST BOUNCE SO I AM OBSERVING BOTH OF THE HEIGHTS THE BALL IS THROWN FROM.

HYPOTHESIS: MAKE A PREDICTION OF WHAT YOU EXPECT TO OBSERVE DURING YOUR INVESTIGATION.

I EXPECT TO SEE THAT THE BALL WILL NOT COME AS FAR UP AS WHERE I DROPPED IT FROM.I THINK THAT IT WILL BE A LITTLE UNDER FROM WHERE I DROP IT FROM.

METHOD: GIVE A STEP BY STEP DESCRIPTION HOW YOUR EXPERIMENT IS TO BE CARRIED OUT.

FIRSTLY I'LL GATHER UP THE EQUIPMENT I NEED, SECONDLY, I WILL SET UP EVERYTHING UP LIKE THE RETORT STAND, THIRDLY ILL PLACE THE BALL WHERE IT SHOULD BE, LASTLY, ILL WATCH HOW FAR THE HEIGHT THAT THE BALL BOUNCES.

KEY VARIABLES

DEPENDANT: I'LL MEASURE HOW HIGH I DROP THE BALL FROM.AND THE HIGHT IT GOES.

INDEPENDENT: I'LL CHANGE THE HIGHT TO SEE IF ANYTHING CHANGES.

CONTROL: I'LL BE IN CONTROL OF MY PROJECT AND EXPERIMENT.

HEIGHTS?

DROPPED FROM                 

1) 100CM                         

2) 200M                        

3) 50CM
4) 70CM                                    
5) 10CM                           

BOUNCE

1) 52.5CM

2) 72.3CM
 3) 17.5CM 
4) 36CM
5) 13.5CM

DISCUSSION: WE DISCUSSED HOW OUR PROJECT TURNED OUT SLIGHTLY DIFFERENT FROM WHAT WE THOUGHT. 

CONCLUSION: WE CAME TO THE CONCLUSION THAT IT DROPPED A BIT UNDER WHAT  I THOUGHT IT WOULD AND THAT THERE IS A DIFFERENCE BETWEEN DROPPING IN HEIGHT AND THE BOUNCE.

EVALOUATION:I THINK THAT WE COULDVE BEEN MORE FOUSED ON THE PROJECT AND MAYBE RECORED THE RESULTS MORE
