KS1 LEGO STEM PROJECT
In Session 2, the children worked together to build an ice hockey model. They then played with their completed models, practising making and blocking shots with a slow, medium, and fast pull force.
The children explored the effects of different strengths of push and pull forces on the motion of an object and investigated how a rack and pinion mechanism works to convert a linear-pull into a rotational push.
In Session 4, the children explored the force of gravity and used it to build a tightrope walker. For this, they had to think about balanced and unbalanced forces and the centre of gravity in order to effectively balance their tightrope walker.
One group commented, “When they stay balanced on top of the rope, the rope pushes up on the walker’s feet to keep them from falling off.”
