'Tinkering in STEM; More Than Fun!'
You may remember the broken bridge that you created while still a child to carry a huge truck, till it came into pieces. You might have tried another one, with better construction to be more solid; once, twice and more. To be more aware and confident with your construction, you might have used your senses to explore the physical properties of materials, took things apart then put them together to figure out how things work.
Whether it worked or not, this is not the point; the idea of constructing such designs with simple tools and having this mindset of creating are what lie behind very important concepts in science learning: tinkering and making.
