Kathy?? Hey its been awhile. How is school going for you? Oh that is unfortunate. I c=would love to help!!! How about we go to my house and take a look.
Hey Michel! School could be going better. Do you think you can help me with my science variables. That sounds lovley
OK that makes sense, But I am still having trouble on control variables and dependent variables.
OK so which question? OK, an independent variable is something that you can directly change during an experimanet.
OK I got it! Thank you so much for the help. Oh I almost forgot can you give me an example? OK Thank you
A dependent variable is something you cannot directly change. A control variable something that you can change but also stays the same. Ya for sure.
The independent variable would be what temperature you set in the house for the ball. Right exactly.
Experiment: What would happen if you put a soccer ball next to a heater and a ac vent?
Oh OK, so you would be able to change the temperature, that is why it is the independent variable. Right?
The dependent variable would be the temperature of the soccer ball before it got placed in front of the vent
That is because you cannot control the temperature of the ball. That is why it is dependent.
You need 3 control variables. They would be Where you drop the ball from, material of the ball, and the size of the ball.
Thank you so much Michael! Now I can turn this in a get 100%.
