Instructions preview
1. The independent variables of this science fair project is the type of water used (salt solution and tap water) and whether the a magnetic field is or is not present. The dependent variable is the time taken for the fluid to flow out of the burette. This is measured using a stopwatch. The constants control variables are the amount of water used, the strength of the permanent magnet used, the flow rate of the burette and the room temperature. 2. The experiment layout is as shown in figure 1 above. 3. Fill 200ml of tap water into the .....
