Perhaps one could expand this experiment to include other types of footwear, but in retrospect, keeping the footwear constant makes the experiment more replicable as well as yielding more accurate data. Good presentation of data; the graph very much help the visualization.","replyPages":[{"page":0,"digests":[],"more":0}]},{"id":"43306962","dateCreated":"1317229697","smartDate":"Sep 28, 2011","userCreated":{"username":"cwu1202","url":"https:\/\/www.wikispaces.com\/user\/view\/cwu1202","imageUrl":"https:\/\/www.wikispaces.com\/i\/user_none_lg.jpg"},"monitored":false,"locked":false,"links":{"self":"https:\/\/tasibgroup4.wikispaces.com\/share\/view\/43306962"},"dateDigested":1532126554,"startDate":null,"sharedType":"discussion","title":"comment","description":"Overall, I think the experiment is well laid out.

Because of this lab, I learned that when I'm wearing flip flops and the floor is wet, I should probably avoid or be more careful when walking on the rubber staircase. The data shows that the track has the higher coefficient of static friction, which probably means the little rubber bumps probably helps to resist slipping.","replyPages":[{"page":0,"digests":[],"more":0}]},{"id":"43239630","dateCreated":"1317142785","smartDate":"Sep 27, 2011","userCreated":{"username":"sunnyc12102866","url":"https:\/\/www.wikispaces.com\/user\/view\/sunnyc12102866","imageUrl":"https:\/\/www.wikispaces.com\/i\/user_none_lg.jpg"},"monitored":false,"locked":false,"links":{"self":"https:\/\/tasibgroup4.wikispaces.com\/share\/view\/43239630"},"dateDigested":1532126554,"startDate":null,"sharedType":"discussion","title":"Comment","description":"I thought the overall experiment was well organized. The graphs were labeled and explained , which made the lab easier to analyze. Sample calculations were also stated, which gave me an easier idea on how you approached your outcome. However I think that this lab could've used more controls, because using just one pair of flip flops, can only determine whether or not that pair of flip flops are dangerous during sunny or rainy days. Flip flops are made with different materials, some of the bottoms of flip flops are made with materials that cause more friction, which can prevent from "sliding" on rainy days.","replyPages":[{"page":0,"digests":[],"more":0}]},{"id":"43221808","dateCreated":"1317125321","smartDate":"Sep 27, 2011","userCreated":{"username":"13103819","url":"https:\/\/www.wikispaces.com\/user\/view\/13103819","imageUrl":"https:\/\/www.wikispaces.com\/i\/user_none_lg.jpg"},"monitored":false,"locked":false,"links":{"self":"https:\/\/tasibgroup4.wikispaces.com\/share\/view\/43221808"},"dateDigested":1532126554,"startDate":null,"sharedType":"discussion","title":"Comment","description":"First of all this lab was very smart in addressing the project\u2019s theme: Environment and Safety. Analyzing the friction of different surfaces when they are wet accurately models situation where students might slip on certain surfaces. One of the limitations was the person pulling the flip-flop, and like Chris said before, maybe a mechanical, constant force can be used to make the data more accurate and precise. Another thing that was not controlled is the amount of water given to each surface. In order to simulate the conditions of a rainy day, maybe a set amount of water should be poured on the surface at a certain height. The conclusion was very helpful in summarizing which surfaces were dangerous and why might they be more dangerous. This lab was very good at efficiently answering the question at hand and was also very informative.","replyPages":[{"page":0,"digests":[],"more":0}]},{"id":"43221554","dateCreated":"1317124973","smartDate":"Sep 27, 2011","userCreated":{"username":"maho1","url":"https:\/\/www.wikispaces.com\/user\/view\/maho1","imageUrl":"https:\/\/www.wikispaces.com\/i\/user_none_lg.jpg"},"monitored":false,"locked":false,"links":{"self":"https:\/\/tasibgroup4.wikispaces.com\/share\/view\/43221554"},"dateDigested":1532126554,"startDate":null,"sharedType":"discussion","title":"Comment ","description":"Your experiment seems to be well planned. It is great that you guys provide photos so it is easier for the readers to understand better.  Also, you guys are very thoughtful on setting up your experiment, such as labeling your graph, providing sample calculations, and setting up the scenario.  You guys not only did the experiment but also looked at some possible errors and limitations, which I think it\u2019s great since you\u2019ll know where you did wrong and how you can possibly fix the problem.  So after going through your experiment, I have a better understanding on where it is the most slippery at school on a rainy day. However, I think there are some improvements that could be made.  For instance, the weight of each person is measured by kilogram and your experiment is set to only 1 kilogram.  It doesn\u2019t seem to be convincing since it cannot represent a real human being\u2019s weight.  Also, when you guys are testing, you should be based on both flip flops and not just one.  Maybe next time, you guys should be more realistic when designing your experiment.  :)","replyPages":[{"page":0,"digests":[],"more":0}]},{"id":"43218004","dateCreated":"1317112833","smartDate":"Sep 27, 2011","userCreated":{"username":"Deborah_P","url":"https:\/\/www.wikispaces.com\/user\/view\/Deborah_P","imageUrl":"https:\/\/www.wikispaces.com\/i\/user_none_lg.jpg"},"monitored":false,"locked":false,"links":{"self":"https:\/\/tasibgroup4.wikispaces.com\/share\/view\/43218004"},"dateDigested":1532126554,"startDate":null,"sharedType":"discussion","title":"Comment ","description":"The choice of topic is very interesting.

Also, the procedure was well thought out. One thing that i thought could have been improved was controlling the speed at which the flip-flop was being pulled. Instead of using the same person to pull the sensor, I would suggest using a toy motor car to pull the sensor or something that will ensure that the velocity is constant as friction can be affected by velocity. Therefore, the results would be more accurate in the sense that the values of friction have the same velocity.","replyPages":[{"page":0,"digests":[],"more":0}]},{"id":"43142798","dateCreated":"1317001981","smartDate":"Sep 25, 2011","userCreated":{"username":"monical12109363","url":"https:\/\/www.wikispaces.com\/user\/view\/monical12109363","imageUrl":"https:\/\/www.wikispaces.com\/i\/user_none_lg.jpg"},"monitored":false,"locked":false,"links":{"self":"https:\/\/tasibgroup4.wikispaces.com\/share\/view\/43142798"},"dateDigested":1532126555,"startDate":null,"sharedType":"discussion","title":"Comment","description":"First off, I liked the way this group organized their lap report.

It would be great if there were some additional explanations on what the different colored lines represented and how the red dots (peaks) were measured.
