Children as young as seven years old have been testing their science skills with their own inventions, and now some of the best are on display in Sydney for National Science Week.
Many have a focus on applications in the real world.
The theme for schools this year is Drones, Droids and Robots.
They are school science projects on steroids, so to speak.
Robotic prosthetics, security systems and drones put together by students of all ages are on display in Sydney this week as part of National Science Week.
There is even a house based on a Frank Lloyd Wright structure, specifically designed for characters in the children's story The Three Little Pigs.
It is eco-friendly and wolf-proof.
