However, Keith Enevoldsen and elements.wlonk.com have created a way to make it more interesting—and far more relevant. Enevoldsen’s “Periodic Table of the Elements, in Pictures” is structured just like a regular periodic table, but each element square contains a tiny drawing and caption. Where the element’s symbol would be, the table shows a familiar object that contains that element.
Some of these things are common knowledge: helium and balloons, or chlorine and swimming pools. However, many of them are surprising and pretty cool. For instance, this chart teaches you that zinc isn’t just a supplement—it’s in brass instruments like trumpets and tubas. Have you ever heard of the element “scandium” before? Us neither—but you’ve interacted with it if you’ve ever ridden a bicycle. We have selenium to thank for copy machines, and the fun-to-say molybdenum is in cutting tools like scissors.

The chart goes even further than that. At the top of each element’s square, there are symbols indicating how often the element is found in nature, whether it’s found in the human body, and whether it is radioactive. Especially if your child is a visual learner, this chart is a great way to help them ace that chemistry test. (Find out if you’re a visual learner.) And there’s more good news—the site even offers printable flash cards with the elements and pictures. Find all the great teaching tools at elements.wlonk.com.
