Parents Need to Know

Parents need to know that Ptable is a website that offers a free, layered, interactive periodic table. It's likely to impress even kids with no previous interest in chemistry. The icing on the cake that parents and teachers alike will love is exposure to academic and professional resources, though knowledge of the IUPAC (International Union of Pure and Applied Chemistry) is assumed twice with no further reference. Though it has no games or activities and might be a bit intimidating for a beginner, motivated kids need no longer search for the definitive periodic table reference: this is it! Plus, it's available in 46 languages including Latin. Pretty cool.

What kids can learn



  • chemistry
  • measurement
  • rocks and minerals
  • substance properties


Thinking & Reasoning

  • asking questions
  • memorization
  • part-whole relationships

Engagement, Approach, Support


It offers plentiful controls, vivid colors, precise text, and nearly limitless choices. Absolute beginners might need less information, and they may long for games, but if you want elemental information, this is the place.

Learning Approach

The site appeals to a range of learning styles with its dynamic interactivity, visuals, and audio. Distinguished sources and references orient older kids to the wide world of chemistry.


Forty-six languages make this table internationally accessible. The ability to save views would be handy, data-wise.

What kids can learn



  • chemistry
  • measurement
  • rocks and minerals
  • substance properties


Thinking & Reasoning

  • asking questions
  • memorization
  • part-whole relationships

Beyond the basics, kids can, for example, display all the elements' states (solid, liquid, gas, or unknown) as color-coded, for the whole table at once, using a slider that ranges from 0 to 6,000 degrees Kelvin. If slid all the way to the left, Helium is shown as the only element with no solid form (blue for liquid) -- interesting. Sliding all the way to the right shows that all the elements can take the form of a gas. Ptable offers dynamic resources in a tight package for casual to serious chemistry buffs or those considering becoming a buff.

What's it about?

PTABLE is a website that offers a free, layered, and interactive periodic table. The main page displays the periodic table, which you can click to get Wikipedia definitions. This page is the default, but you can also select definitions, videos, podcasts, or images, including visuals of common products that contain an element (such as older-style batteries, sushi, and vermillion paint for mercury). You can learn about the 18 groups of elements, interactively explore 16 properties and their subproperties, view images of orbitals, list selected or all isotopes, and iterate compounds, plus much more.

Is it any good?


Ptable is awesome for kids truly interested in chemistry or who have a parent who wants to get them interested. The sheer quantity of information about each element, from atomic number to abundance in the universe, is quite enough, but then add color codes, dynamic and interactive data, links to a complete set of videos and podcasts from distinguished sources, and striking and orderable images and posters, and you've got a website with some serious depth. Need more? Creator Michael Dayah provides a video demo of the site (though it's a bit on the speedy-yet-cursory side), plus he outlines the site history, navigation features, sources, search techniques, and troubleshooting tips.

It can be tricky to discern the selected element, and, if you're looking for a place to get a younger kid started, the Jefferson Lab site is more plain and accessible, plus it has games, puzzles, and a student zone ( On the other hand, if you want to launch your chem-head kid into a new world of understanding, Ptable, in Dayah's own words, makes "Mendeleev's creation come alive."

Families can talk about...

  • Families can talk about how memorization can be boring at first, but, with a subject like the elements, there's a lot of interesting information beyond abbreviations.

  • Help your kids think about the elements by finding examples in your own home. What items contain which elements? Are they important items?
