How can X-rays see through you? 🔍🦴

You’ve hurt your arm, but is a bone broken? How can doctors find out without opening you up? This week’s excellent question comes from Poorvith, who is six and from Melbourne. Poorvith was fascinated by his own X-ray and CT scan.

Join Christie as she investigates how invisible X-rays reveal our bones, why CT scanners create virtual “slices” of our bodies, and how ultrasound and MRI use sound and magnets to explore our insides. Different machines, some very clever science, and your skeleton stays right where it belongs!

Got a science question you’d love answered? Email it to us with your first name, age and where you’re from, and Christie could investigate it in a future Squiz Kids Science Short!
