Hypothesis: Our hypothesis is that the maple syrup will make the marble go slower then water, or veggie oil. Because maple syrup is stickier then water and is thicker. Procedure 1st Take your liquid and pour it into a 100ml beaker, until it reaches 100ml. 2nd Take your marble and drop it exactly 1cm, above the beaker. 3rd Observe how fast the marble goes down. 4Th Report it. 5th Repeat all four steps, three times. Variables The height drop from – Control Variable When we started or stopped the stopwatch- Control Variable Type of Marble - Control Variable The type of fluid – In depended Amount of fluid – Depended

Conclusion: Our hypothesis was right. The maple syrup made the marble go the slowest. When we dropped the marble in the beaker with water, it went an average of 0.35 seconds. When we dropped the marble in the beaker with maple syrup it went an average of 7.94 seconds. There is a big difference between those two. So for the rehab scenario, if you were to choose from using water, veggie oil, or maple syrup to help people get their muscles back. Use maple syrup. The data collected for the trials are not exactly the same because different fluids and different fluids have different particles, so they have different viscosity. Since they have different viscosity, the marble didn’t go the same for every test. It took 7.28 seconds for our first try of maple syrup, 7.90 seconds for our second try, and 8.66 seconds for our last. The reason that there not the same is because we can’t make a fair test, so we might have started the stopwatch too fast for the first test, or too slow for the second. I think that the results are what they are because of viscosity. Viscosity is the thickness in a fluid. The thickness of a fluid can be effected by how big or small the particles are, or what temperature it’s at. The maple syrup went the slowest because it was sticky, which means that the particles are probably attracted to each other. Since the particles are attracted to each other they move a lot slower. If the particles of the maple syrup were colder, they would move slower making the maple syrup have more viscous. But the most important factor in determining a fluid’s viscosity, is the strength of the attraction between the particles.
