Real X-Rays With Preschoolers

Looking at real x-rays with preschoolers is a fun way to talk about the human body and engage young children in real world science!

I will be sharing Letter "X" preschool activities all week!  Be sure to join us!!

As part of our Letter "X" day, we looked at real x-rays with our preschoolers.  This is a fabulous way to jump into the science of the human body!  Here are a few discovery points for x-rays and preschoolers:

* Bones are inside our body!  Encourage your preschoolers to find hard bones on themselves.  (Elbows, arm bones, and leg bones were the first bones bones our kiddos pointed out.)

* Look at a picture in a book (or print one from the internet) showing a skeleton.  Most people have about 206 bones.  Each foot has 26 bones!  Can you find them in the picture?

* Bones re-grow constantly!  Ask your children if they have ever broken a bone?  It can take about two months for a bone to re-grow.

* X-rays machines work like cameras.  They send x-rays (instead of light) into your body.  The x-rays can pass right through tissue like skin, but most x-rays bounce off of hard things like bones.  In the picture above, you can see the bones and the foot around them.  The soft parts of the foot look like a cloud.

Looking at x-ray films requires light to shine onto the film.  You can hold the x-ray film up to the window, use a pre-made light box, or make your own simple light box.  (If you want to buy one, I have affiliate links at the bottom of this post.)

I prefer to use a simple home-made light box.  I have a string of white Christmas lights that I keep handy for when I need one.  Just place your string of lights inside a large transparent bucket (I use a big Sterilite container), snap the lid back on, and plug them in!  Ta da!  Instant light box!  Turn off surrounding lights for the best effect!

To use it with your x-rays, simply place the x-ray on top of the light box.

We had an x-ray of my daughter's foot because she broke some toes last summer.  If you don't have any x-rays, you can use pictures, buy an x-ray set (see affiliate link below), or make your own x-ray images like The Measured Mom.

I will be posting more Letter "X" activities during the next sure to check back and get them all!!

Below are Amazon affiliate links for x-rays and light boxes.  Buying after clicking on the link never costs you more money, but I do get a small commission for referring you.  Thank you for supporting our homeschooling family!!

I may share at any of these parties!
