On Tuesday morning, children in Years 3 and 4 continued their investigations into friction. They had a competition to see how many sugar cubes they could move from one tray to another, using chopsticks! Afterwards, they repeated the same experiment using ice cubes and were able to discuss whether they thought this would be easier or harder, using their scientific understanding to help with their explanations.
They went on to consider what we do to help stay safe when walking and driving around in winter months, when there is ice on the floor and thought about whether or not adding salt to ice cubes would make them have more friction. They were very interested to find that the ice cubes became even more slippery, meaning less friction - because the salt was melting the ice more quickly!
