What our experts think

The Obstacle Set from Gravitrax encourages children to work together and think logically to successfully build a working course. Construction sets like this that combine open-ended creative play with STEM learning are great because they allow children the freedom to engage their imagination and design what they want, while learning key principles of science and technology, such as magnetism and kinetic energy. 

While the children found the instructions a little tricky at first, by working together with their peers who were familiar with other Gravitrax sets, they soon got the hang of building together. Collaborating together in problem-solving is great for children’s social and emotional development as it teaches them about negotiation, communication and resilience.
