Clever Activity Teaches Kids about Refraction

$playing with refraction with water and light$ This is a super simple activity that you can do anywhere you have a glass of water and some paper and a pen. Go Science Girls has a full rundown of different options and ideas for playing with refraction, starting with as simple a thing as drawing two arrows and then looking at one or both through a glass of water.

The arrows seem to change direction depending on how you look at them. Likewise, other things you draw will change position or how they look based on how you look through a glass of water at them and the position of the glass relative to the paper and your eye.

She explains how this works thus:

What we are seeing here is a physics concept called refraction, or the bending of light. When light passes through transparent objects (in this case, the front of the glass, the water, and the back of the glass), it refracts or bends. When the glass is full of water, it acts as a cylindrical convex lens, and produces an inverted image. The inverted image may appear larger, smaller or the same size, depending on where you position the paper, the glass, and your viewpoint. Another variable is the size (diameter) of the glass.

This is such a clever idea and it’s sure to keep even little kids entertained while waiting for food at a restaurant or whenever else you need a little activity to fill time. Older kids can draw their own pictures and observe how they change when looking through the glass. So fun.

The other day I shared some crafts involving fall leaves, but there are a lot of fun leaf-related activities that don’t use real leaves, so I wanted to share some of those, too.

Like these watercolor leaves from The Artful Parent. These are so pretty and would be great to make a garland or decorate the table for Thanksgiving. You could experiment with different kinds of paper, combine watercolors and crayons, use an eyedropper to apply liquid watercolors — there are lots of different ways to play with this one!

Because I’m a knitter of course I love any project that involves yarn, so this fall leaf lacing craft from Our Kid Things is right up my alley. The multicolored yarn they used is a lot of fun, or stick with fall colors. Either way it’s a great fine motor skill activity!

Using leaf shapes to make other crafts is a great way to incorporate leaves into the classroom without having to use actual leaves. For little kids this sensory painting activity from Kids Craft Room would be a lot of fun (I think this would be fun for some older kids and adults, too, to be honest) and makes a fun and easy decoration.

Of course leaf activities don’t just have to be crafts. Check out this great leaf matching game from Made to be a Momma. These leaves are so cute and after you’ve prepped the game you can play it over and over with no prep. Use fewer sets for younger kids and the full set for older ones.

You can also use leaf shapes in all sorts of learning activities, like in this fall leaf number tower activity from Fun Learning for Kids. There are leaves with single numbers on them that kids can use to stack cubes on in one-to-one correspondence, as well as ones that show dots like dice so kids can add up the numbers to build their stacks.
