• Hello! You look like you are doing something interesting! What might you be doing?
• Well, I was thinking: How does the outside temperature affect the height of the ball on the first bounce!
• Well before you actually start your experiment you must understand what independent,control,and dependent variables are.
• Well what are they !
• Well the independent variable is the thing that you are changing in your experiment. The independent variable in your experiment is the temperature
• Now since we are in the arctic it is much colder. This might affect how high the ball bounces. It will also keep on changing no matter where you go because of the different temperature.
• I understand now! So cool! How about control variables?
• A control variable is something that you need to keep the same in order for the experiment to not controlled by you. Such as: The ball's height , the material, and the force used to drop the ball.
• Wow, thanks. Those examples were very handy! What are dependent variables?
• Lastly we have our dependent variables. Our dependent variable is the height of the ball on first bounce. It is called this because it dependents on both the other variables to get accurate results.
• Thanks for the explanation but why do I have to know this?
• These variables are useful so you know what you are actually doing during an experiment. It also helps you understand and keep track of when you are doing your experiment. I liked our journey. Well have fun with your experiment!
• Thank you so much. Now I have a much better understanding of what I will do during my experiment! Bye!
