The idea of this investigation came from curiosity that I had ever since I was younger. I questioned why honey had a slower flow than water. This is a liquid’s resistance to flow and that is otherwise known as viscosity. This a concept that people would call thickness of a liquid. It makes sense that the thicker the liquid the viscosity would be greater. Viscosity describes the friction of a moving liquid. A liquid with high viscosity resists motion due to the fact its molecular composition gives it a lot of friction inside. A fluid with lower viscosity flows with ease because its molecular composition has very little friction when it is flowing. In between the molecules of the substance there are intermolecular forces which have an influence

Due to this we have reason to believe that the molecules in liquids will also increase the flow and decrees the viscosity. That is why when you heat up cooking oil it becomes liquefied like water and why if you freeze water it becomes ice and reach a point of no flow. In this investigation we use an inclined plane to measure the flow of the various liquids that were experimented with. There were five substances that were experimented with along a platform at a constant angle and the time was looked at by how fast each substance got to from point A to point B. We are using a kinematic viscosity which means gravity will help the flow of the substances and also it is a factor in calculating the …show more content…

Height of incline(cm) 27
Angle of Incline 64.3ᵒ
Uncertainty in Raw Data
The experimental data were cited with varying precision ranging from zero to three decimal places. There were five trials for each substance resulting in 25 complete trials so the data is fairly reliable. Also the time that the liquids go from point A to point B could have been affected by how fast the time recorder realized that it started flowing. Also the way the liquids were poured where some of the liquids flowed slowly out and could have resulted in not all of it coming out in one time. This factor was avoided as much as possible.

Conclusion
Overall the conclusions were the following in order from highest viscosity to least viscosity:
- Basics Liquid Hand Soap
- Light Corn Syrup
- Pure Canola Oil
- Mrs. Butter's Original Syrup
- Ionized Sink
