FALLING TIME Raynaldo 6B

Problem  What will happen if thick liquid and thin liquid is mixed up together and the small ball is dropped? Will it go faster or slower?

Background research  The liquid will fill up the shape of a container. If some water is poured (H2o) it will fill up the bottom of the cup first and then fill the rest. The top part of a liquid will usually have a flat surface. The flat surface is the result of gravity pulling on some substances that holds chemical

Hypothesis  If I put the ball bearing in a thicker liquid such as honey, then the duration of the ball bearing to reach the bottom surface will be much slower than the other liquid materials for the ball bearing to reach.

Variables  Independent: liquid types and amount of liquid(3/4)  Dependent: Duration  Control: Size of bottle(texture), size of ball bearing. Temperature of liquid water

EQUIPMENT  Bottle  Ball bearing  Stop watch  Marker/Magic marker

Material  Different types of liquid  Water

Steps  Pour a small glass bottle about ¾ full of 'cooking oil’(or others) and mark the level of the liquid with a magic marker. This mark will be used when testing the other liquids so that a constant level is used and the liquids can be properly compared.  Drop a small ball bearing (about 10mm diameter) into the liquid in the bottle and use a stopwatch to time the number of seconds it takes for the ball bearing to fall to the bottom of the bottle.  Do the procedure two more times, and each time record the results to claim(have) the average falling time for each of the liquids tested.  Repeat steps 1 to 3 for the 'baby oil', 'syrup’(or others) and other substances you might want to test.  Draw up a data chart to compare the viscosity of various liquid substances.

Conclusion  My Hypothesis is correct, because the thicker liquid gives more protection for the gravity to pull the ball bearing to the bottom surface. So the duration of the thicker liquid is much slower than the other liquids, even they have different process.

Qualitative, quantitative and similarities of my experiment QUALITATIVESimilarities QUANTITATIVE -My qualitative in my experiment is the water liquid which is easy to be predictable by our own logic. -My qualitative is also the honey liquid which is also easy to be predicted because thicker liquid also give less duration -My qualitative is also the water because it just shows a quality characteristic and not to experimental to be predicted. -My qualitative is the bottle because it is only as needed to do the experiment and not to involved with scientific works. - The amount of water is also qualitative because it is not to important of its amount. -Both gives an information of the durations. -Both uses a liquid to represent the duration of the information. -My quantitative project is measuring the duration of cajuput oil and cooking oil which is not easy to be predicted. - My quantitative is also the stopwatch me and my partner used which the systemic material can measure the duration of each fallings. -My quantitative is also the ball bearing because it is used to be measured on the liquids. - the marker could also be the measuric tools to know each amount of liquid. - The types of liquid could also be one of the quantitative because those is used to project the experiment held.
