Experiment #2. Attempt for results

I have gathered all my equipment for the second attempt of my experiment but I have made some major changes to my whole experiment. A re-written version of this can be found below.

Aim: To determine the viscosity of honey at different temperatures through the use of marbles

Hypothesis: The higher the temperature of the honey the lower the viscosity. In other words, the hotter the honey the faster the marble will sink

Equipment: 2 L of ONE type of honey, 4 same type of marbles, stop watch, 1 L measuring cup, 4 empty jars, permanent marker

Variables:
Independent: The temperature of the honey
Dependent: The time taken for a marble to sink to the bottom of the jar
Controlled: Same amount of honey, same type of marble, same size of marble

Method:
1. Name the 4 empty jars: Room, 20, 30 and 40. This will indicate the amount of time needed for it to be microwaved.
2. Pour 500 ml of honey into each jar
3. Place a marble into jar 1 and start the stop watch
4. Time how long it takes for the golf ball to sink to the bottom
5. Record your first time into a table
6. Microwave the jar named 20 for 20 seconds
7. Repeat step 3-4 and record the results into the table
8. Repeat step number 6 and 7 but this time use the different jars and microwave at different temperatures as indicated by the number on the jar
9. Repeat the experiment 3 or 4 times to increase reliability and validity
10. Graph the results
