On Wednesday, we asked the question: What slope angle is required to generate sufficient energy for a marble to complete a loop-the-loop? We set up the investigation and then made predictions, observed our findings and drew a conclusion. There was lots of great discussion, drawing from prior knowledge regarding centipetal force!

Today, the children were learning about gravity and the force it exerts upon objects. In this particular experiment; a pendulum. Children planned an investigation: Do the oscillations across 1 minute increase, decrease or remain the same as an object becomes heavier? As we conducted a fair test and the children were surprised to find that, regardless of the weight, the number of oscillations remained the same: 29 per minute. The children concluded that this was all to do with gravity and regardless of the weight of an object, gravity remains a constant force acting upon it.
