Students in Grade Four spent this morning working on an experiment designed to investigate whether changing pressure or height altered water flow. They filled a bottle with water and punched holes at regular intervals along the bottle. They then looked at whether the height of the hole altered the flow. Some enterprising individuals also checked to see if squeezing the bottle made a difference. The students noticed that yes, there was indeed a difference in how far the water went. This led to a discussion on how water flow was most easily harnessed in dams, and how water pressure could create faster and more dangerous rivers. It was a busy morning with students highly engaged… and at the end, rather wet!
