hm, I wonder if the type of sport ball I use, affects how far I can throw it!
(that is my experiment, you must make it clear to readers and tell them what you are actually doing)
The basketball went not that far. It only went 329 cm away. The basketball is larger and heavier than the other sport balls. It is harder to throw than a baseball and a tennis ball.
This step is important to our experiment because this is when the change will happen. This step must be done to find our outcome
So this is my first variable, the independant variable. This is the variable that changes through out my experiment
In this case my independent variable will be the type of ball I use
NOW LETS DO THAT AGAIN 2 MORE TIMES
This step is important because it gives us our results to the experiment!
The independent and dependent variables will change a lot. All 3 balls are different in weight and mass. Air pressure as well. It will change the outcome.
Now that was just my dependent variable. It is the second part of my experiment, it is the outcome. The baseball went 500cm far
The tennis ball went a bit further, it went 536 cm far. The tennis ball is also lighter and smaller, making it easier to throw
I hope you liked the experiment!
To make sure that this experiment is going correct, we must notice the control variables. Those are the variables that stay the same the whole time to make sure it is correct. For me, I must make sure that the floor I'm throwing the ball on stays the same. I also have to make sure that the force and angle I'm throwing stays the same. Of course I am only human, so it's not gonna be perfect.
