Science day- Da Vinci bridge challenge!

Who invented the first bridge? What are the purposes of the bridge? Which types of bridges are the strongest? How did ancient people build a bridge, and how fast can the soldier assemble the Da Vinci bridge?
All these questions came from the children. The great thing about Montessori is the “hands-on learning” and allowing children to explore and investigate.
“The answer comes from our exploration and the curiosity to investigate.”
