This experiment investigated the cohesion and surface tension of a penny when water and soap is dropped on it. In order to study the problem we put water into a eye dropper and careful out water drops on the penny one by one. Results showed that the penny can withstand the surface tension with just water with the average of 22 drops but soap on the other hand was different with the average of 5 drops. This proved my hypothesis accurate as the cohesion and surface tension decreased the more water was added especially with the soap because mixing the hydrogen and oxygen molecules caused the molecules to bond less. The Results with group one were similar between the averages of drops of water and soap on the penny as the differences were not the exact numbers and how fast we did each trial. To extend this experiment what if we used a bigger coin, for example a toonie. Would there be more surface tension because the coin is bigger? What if we put soda in the eye dropper instead of the water considering that soda fizzes and the cohesion of the liquid would change jurrasticly.
-98 pennies were held before the boat sank.
-We all drew out ideas before assembling, Our group member Moe had a solid drawing so we took his solution and we coped with that.
-We had a solid execution with our boat “Big chungus” considering we almost made it hold 100 I feel if more time was made into it we’d pass the 100 penny mark.
My strengths as a learner are that I’m good at memorizing things and knowing what do do.Remembering things goes a long way in terms of learning, its very helpful in so many situations in learning.My curiosity is also one of my biggest strengths. Curiosity makes me want to learn more about things when I am interested.My curiosity brings me to be more creative as a learner and when I do work.Which leads to one of my other strengths as a learner.Creativity.Being creative strengthens mylearning abilities like for example,it makes me think outside the box and make my own way to do things as an individual.I usually learn best when I want to,or in a group.Working as an individual is sometimes hard for me.I learn the best when there is no distractions and noise when I’m working.
My prediction for what fruit will have the most voltage would be an orange.The reason why is because I would think the more sour the fruit the more voltage that’s why lemons would work also.
