The Amazing World of Fish Creek Park. At Fish Creek Park we did a lot of neat things with water. We used thermometers to see how cold the water and the air was. We noticed that the air was colder than the water. Reading a thermometer is tricky and it was hard to see where the red line stopped. We went on a scavenger hunt looking for signs of winter. We found LOTS of signs ... like snow… everywhere. It was amazing! Some of us were trying to catch snow on our tongues. We also found some cool looking ice and slush in the river. Besides the snow, there were a lot of very exciting things that greeted us at the park. We saw a coyote, lots of wax wing birds, some canadian geese, chickidees, a big black crow, and black fungus growing on the trees. One of the activities was a nature walk. Along the walk we chose sticks for the “Great Stick Race.” We were looking for sticks that would be fast and steer through the rocks. We looked for sticks that had a rudder, small and pointy, smooth so they would ‘cut’ through the water really fast. This activity reminded us of the boat designs we have been looking at while building our boats.

This week we were given a challenge: To make boats using recycled materials that would hold weight. The first thing we needed to do was test the different materials to see how they would react in water. Through this experiment, we discovered that materials: - absorb (soak up) water - dissolve (become one with the water so that we can not get it out of the water) in water - disintegrate (break into little pieces) in the water - are water proof (does not soak up any water) We found out that ...We tested a sponge and discovered that when the bottom of it got wet, it soaked up (absorbed) water and would flip so the dry side would stick out of the water. When we tested the tin foil, we found out that the shape made difference. If you put the tin foil in the water flat, would float below the surface of the water. If you rolled it into a ball, it would sink. However, if you curved the edges, it would carry some weight. Another material we tested was a milk carton. We learned that an empty milk carton would float. But if we put water inside the milk carton, it would get lower and lower in the water until it touched the bottom. We also remembered things like if you put heavier objects on lights things, it would float. Stay tuned for next week when we start to build our boats! |
