Popcorn – the world’s favourite snack and certainly an all time favourite with kids. But have you ever wondered why does the corn POP?
Popcorn kernels contain teeny-tiny amount of water inside them. When this water is heated, it changes into steam. Much like in a pressure cooker, this steam needs to escape from the kernel. So it forces the kernel to POP open.
Now, pop some corn in a kettle with your kids and mull over the question for a fun Popcorn STEM conversation. Allow their imaginations to run wild, before you explain them. Ask your kids if they can think why Roti puffs up?
Finally, take your kid’s knowledge a step further with our Popcorn STEM Investigation. We had of fun and learning doing this.
