The tinkerers worked together today to make the crane tower stronger and safer. We checked for areas where screws may have been too short or the wrong size, we also looked for gaps in our construction, and checked the overall stability of the structure.
Leo presented an idea for a swivel top so that the crane arm could move from side to side. His plan consisted of attaching wheels onto the crane arm and adding handles onto the end of the arm to control its movement. At the end of our session everyone made drawings to share how we collaborated with each other.
