Homework Help: 6th grade science fair project

Posted by Reed on Wednesday, February 16, 2011 at 10:00am.

Each week up until fair time we have to turn in one aspect of our project. This week it deals with our conrol, dependent and independent variables and constants. I will tell you that I got my idea form sciencebuddies. My project is Ocean Currents: Modeling the 'Global Conveyor belt' in your kitchen. My objective is to measure how the heat input affects the velocity of the currents. My problem was- Does an increase in water temperature affect the velocity of ocean currents? My hypothesis is-- Raising the temperature of the vegetable and thyme mixture will increase the velocity of the mixtures movement. Now this is where my question comes in, am I correct in saying that my Independent variable is-HEAT. The Control is----The time the mixture is heated for. My 1st variable change is-- Heat applied, my 2nd variable change is--item appling the heat(candle versus sterno can), my 3rd variable change is--spot of heat application (depth). My Dependent variable is---velocity of the currents. My constants are--The vegetable oil and thyme. CAN YOU PLEASE LET ME KNOW IF THIS SOUNDS LIKE WHAT MY TEACHER WANTS. I have received 100's on the previous 3 pieces of information I had to turn in but I am worried about this one.
