This activity was about movement over and under the bridge. The children used curved blocks and cars for their exploration. The children enjoyed moving the cars over and under the bridges. Some children used one curved block, and they decided to move the car over and under it. Some children were interested in lining up many bridges, and they moved the car over and under them. The children were talking about their exploration, and some children believed that cars move over the bridge only not under it. Some children worked together lining up the curve blocks and they used different cars for their movements. We plan to explore the movement across the water, with the use of bridges, to see how children will react when they see the movement over the water not under.
