Zooming Hearts – a fun Valentine’s Day science activity kids love!

Zooming hearts science activity

This is such a cute and fun science activity for Valentine’s Day (or any day)! Can you make a paper heart zoom? If you’re sneaky with the dipping part, you can also make it look like a cool party trick and amaze your friends. Science magic!

Suitable for

This activity is fun for a bunch of age groups, from preschoolers to grade school kids. Jewel is 9 and Bumble Bee is 7 in the videos below – they can easily do all the elements without help, but they still found it fun!

‘Magic’ Drawing with Refraction of Light: an art meets science activity for kids

How to ‘magically flip’ drawings using refraction of light. Fun art meets science activity for kids.

Create magic drawing with refraction of light - fun art meets science activity for kids

This is a fun ‘magic’ science trick that even little kids can do.

Draw two arrows, both pointing the same way, and then look at one (or both) through a glass of water. Which way are they pointing now? Does it matter how far away the glass of water is? What happens if you move your head from side to side?

Suitable for

This activity is fun for 5-6 year olds. (Younger kids can certainly have a go too, but they don’t seem to be as amazed as the school-aged crew are.)

Thumb image flipped due to refraction

You can do this science experiment almost anywhere. I love that it’s one of those activities that takes just a few minutes to set up and do, although you can spend more time on it if you want to. It’s also practically free as well, as it uses only common everyday items.

We’ve done this experiment a couple of times when we’re at a restaurant with the kids, as a way to keep everyone entertained while we wait for the food to arrive….

Drawing of a girl with 'magic' eyes due to refraction of light

What you need:

  • glass of water
  • paper (or paper napkin works if you’re at a restaurant)
  • pen

Draw something on a piece of paper, and see how it looks when you look through a glass of water. You don’t have to limit it to arrows! Be creative! You can draw anything you like and see how it looks through the glass.

Questions to ponder: How does your picture change? What bits stay the same? Does image size matter? What happens if you try with a wider (or narrower) glass? What happens if you move the glass closer to the image? Or further away? You could use a ruler to measure the distances and record your results. Does it change if you look at it straight on or slightly from the side?

A fun idea is to draw a picture of a face, with the eyes looking one way, and see which way the eyes are looking when you look through the glass.

Can you change the variables around so that the girl is looking at herself?

The more creative you are, the more this activity becomes a STEM + Art, or STEAM activity. STEAM is a way to link art into STEM activities, which is a great way to make STEM subjects fun and relevant for young kids, especially those who are creatively inclined.

JJ drawing a girl and then seeing it change due to refraction

Once you’ve played around with it for a while, can you start to guess (hypothesise) how you think a picture might look given particular variables, and then look through the glass to check if your hypothesis was correct?

Art and Science - flipping drawings using refraction of light

Fun Science

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.
