Cole's Evidence of Learning

                                        Burning Oxygen On the 6th of June 2017, the same group of people that did " Elephant Toothpaste " also did an experiment on candles called "Burning Oxygen." The experiment we were seeing if candles would burn longer with more oxygen, or less. To do the experiment we were going to have; 4 candles, 4 cups of different sizes, 4 stopwatches and something to light the candles. What we were doing was lighting the candles, then getting the stopwatches ready, putting the cups  on the candles and immediately after starting the stopwatch. The cup sizes we had was; small, 2 medium ones, (one smaller and one bigger) and a large cup.                                  Conclusion The results were: •   Large cup: 11.40 s • Medium 2 cup: 8....

Today in immersion we were learning about all types of energy and forces. In the image shown above, we had to create a roller coaster than was both safe and fun. With the roller coaster it stored lots of potential energy going up to the top of the first hill, but it released too much kinetic energy going down the hill causing it to go too fast making it an unsafe and not fun ride. The Next time I tried to make it much safer and as you can see, it was more safe but not as fun. It was not as fun because it did not release  as much kinetic energy, making it a slow and dull ride. The last time I mixed the two together, making it fun and exciting but also very safe. At the start I wanted to make a big hill, but not too big because it would release too much kinetic energy making it go much too fast. The next bump I didn't want to make too big either because it would send the roller coaster flying and with the final hill I made it really bi...
