Investigating Water Resistance

We have had a great time this week investigating water resistance in science. The children thought about what it felt like to move in the water and discussed the forces that were apparent. We thought about how we could make it easier to move through the water by adopting a streamlined shape. We decided to investigate this by planning investigations using plastercine and giant cylinders to test which shape moved through the water the quickest, and which shape would move through the water the slowest. The children used timers to time how long it took the shape to fall and recorded their results in a table. We found out that the more streamlined the shape the faster it would move through the water.
