English term or phrase: set of slotted masses
The strength of thread is an important property to consider. Encourage the children to design an investigation to compare this. They could attach each thread to a set of slotted masses, gradually increasing the number of weights to find each thread’s breaking strength. Safety note: Hang the weights over a container of sand to avoid them falling on children.
