Plan: were going to take a dish fill it with a liquid and run a marble through the liquid and see how long it takes to sink to the bottom. Hypothesis: we thought that the water would be the least thick Bowl/Beaker, anything that has depth (our choice was a graduated cylinder) Water Corn oil Corn syrup Stop-watch Procedure:

Step 1:get the materials needed. Step 2: get the water and a 100ml graduated cylinder and fill it with water to the 75 ml line. Step 3: drop the marble in the water and time how long it takes to reach the bottom. Step 4:repeat that test 3 times then level it out. Step 5: get the corn syrup fill it to the 75ml line then drop the marble in it, time how long it takes to reach the bottom then repeat 3 times then level out the average. Step 6: get the corn oil fill the graduated cylinder to the 75ml line and drop the marble and time how long it takes to reach the bottom. Step 7: repeat the test 3 times then level out the average. Step 8:See which liquid had the slowest time and which had the quickest time. Step 9:make sure your hypothesis was correct if not explain why not explain how you could have improved the experiment.

Control variables: 75m of the liquid Its always a graduated cylinder Its always dropped from the top of the grraduated cylinder

Independent variables: Its always got 3 liquids, water, corn oil and corn syrup (our choice)

Dependent variables: we measure how long it takes to get to bottom of container.

Conclusion: rehab scenario: if you are trying to get muscle back use water then corn oil and at the last of it use corn syrup because water is the lewast thick, corn oil was second best and corn syrup was really thick.

particles theory: there are a couple reasons why the water is the least thick and corn syrup.

first reason:it could be because of heat differences which makes the particles move slower and more thick or hotter and faster moving particles.

second reason:small particles move quicker while larger particles move slower. water might contain small particles.

third reason: bulky particles flow past each other slower then less bulky. like how the corn syrup was really hard to move through so they might have bulky particles.

fourth reason: the particles might stay together and make the liquid thick or they may be spread out and really thin in viscosity. like how the corn syrup is really thick and sticky.

differences: the liquids changed so the trials changed of coarse but the person timing it was also changed at times so that could be another reason.

Sources of error: we don’t know if we stopped the timer at exactly the right time
