Periodic Table of Elements Archives - Eva Varga

Just prior to Thanksgiving, I downloaded a new app called Atomidoodle for our iPad. It looked both educational and fun. We were driving up to Oregon to see family and in the rush to pack and load everything into the car, I neglected to tell the kids about it.

After gathering with family at my brother’s house, the kids went home with their Grandma for the night. We picked them up the following day and drove home. The drive takes about 5 hours and often, the kids will engage themselves in reading, practicing their Mandarin, and playing games or reading iBooks on their devices.

atomidoodleThe next week, I sat down on the couch and called them over to share with them the new app I had downloaded. Much to my surprise, they had already discovered it. “Atomidoodle! I love that game,” my daughter exclaimed. “I found it on the iPad when we were at Grandma’s house and I played it a bunch. It is so fun!”

We received the Atomidoodle app in exchange for an honest review. I also received monetary compensation for my time spent in reviewing the product.  All opinions expressed are true and completely our own. Please see my disclosure policy for more information. 

My daughter doesn’t play video games very often. Hearing her speak so highly of the game, I couldn’t wait to play it myself. I asked her to show me and I quickly discovered what she enjoyed so much. We have since enjoyed playing together (taking turns) on several occasions.

I love that she is learning as she is engrossed in a game. Trying to collect all the elements in the periodic table is also a great challenge to keep her motivated.


Within the game, there are pathways that the little atom travels upon. The goal is to move the number of atoms requested to the final destination before time runs out or the atoms crash into one another.

As each atom pops out of the generator, you direct it along its route to divide (using the fission widget) or combine (using the fusion widget) the atom to create different atoms.

Let’s say the game asks for a 5-Boron atom. If 5-Boron comes through the portal, you can lead it directly to the end of the route. However, if anything else arrives, you have to keep it moving along the course.

When an atom is directed to the fission widget where atoms are split as evenly as possible. Even numbered atoms are split exactly in half whereas odd numbered atoms are split as close as possible (9-Fluorine, for example, will be split into 4-Beryllium and 5-Boron).

Conversely, the fusion widget combines atoms. If the game asks for a 5-Boron atom, you’ll need to join smaller atoms together. Direct two 2-Helium atoms into this widget will result in 4-Beryllium. Direct a 1-Hydrogen to the widget together with 4-Beryllium and you’ll create the 5-Boron atom you need.

While the game aspect is so very fun, it is also educational! Each time a goal is reached, you unlock one of the elements on the Periodic Table of Elements. Fun facts and trivia are revealed along the way.

The game keeps you on your toes! As you race the computer to achieve your goal, target goal will change mid game. As you advance, the game board also changes and the atoms are generated more rapidly.


Atomidoodle, a gaming app by Hero Factor Games, provides kids a fun and engaging way to learn about the periodic table and practice their math skills. It is a simple, yet action-packed puzzler based on the Periodic Table of Elements.

Created by a husband and wife team who have enjoyed playing video games since their childhood, Atomidoodle is fast paced, mentally stimulating, and hard to put down.  Due to their lifelong love of video games, they know how to weave positive content into exciting, challenging, and rewarding gameplay, so that kids are enjoyably edified!

The latest release includes hundreds of interesting trivia facts. Atomidoodle is a virtual chemistry notebook come to life with speedy atoms, challenging mazes, and colorful doodles.

  • Draw paths through tricky mazes, and get atoms safely to the goal
  • Use fission (division) and fusion (addition) to create new atoms
  • Think fast to avoid explosions
  • Discover the elements and complete the Periodic Table
  • Unlock hundreds of facts about the elements
  • Eye-catching, hand-drawn artwork

Atomidoodle is available for iPads on iTunes and is now also available on Android tablets as well! You can grab it on the Google Play store.

Young children learn best through hands-on science, or simply “doing.” They learn about the world around them primarily by experiencing it through their senses.

For this reason it is important to focus science lessons around things that they can see, hear, touch, taste, and smell. Late last week, we began a chemistry unit.

I don’t believe I have seen the kids more excited about a subject before. Particularly my daughter who just two days ago checked out four books on specific elements, a fun introductory book on the periodic table, as well as a book of fun experiments. She has already read 3 of them!

Electrolysis of Water

One of the first experiments we undertook enabled us to observe the electrolysis of water; separating the elements in water (hydrogen and oxygen) into their gaseous state.  

The setup was very simple and the kids were ecstatic with what they observed.  We had to look closely, as the bubbles were small, but we indeed could see the accumulation of oxygen gas (O2) and hydrogen gas (‎H2) on the electrodes. Note: we used two pencil lead refills, a polymer carbon, not the element we know of as lead).

As we all know, the chemical formula for water is  ‎H2O. This means there are twice as many hydrogen molecules as oxygen molecules.  When electricity is introduced to water, the molecules split with hydrogen gas (H2) appearing at the cathode.  Since there are more hydrogen molecules than oxygen molecules in water, the electrode that the hydrogen collect upon will have more bubbles.

I asked them to draw their observations in their science journals and their enthusiasm for the subject carried over. Labels, measurements, and careful diagrams were encouraged. I love that they used the chemical symbols for the elements.

Further Exploration

As they are young yet, I didn’t discuss with them the process of reduction or oxidation.  Our focus was simply to understand that by passing a current of electricity through the water, we could separate the atoms of water to get a pure element.  

I have been reading aloud Kathleen Krull’s Marie Curie (Giants of Science). Through much of the book, the author discusses how Marie and her husband Pierre worked tirelessly to isolate radium from a complex compound called Pitchblende.  This simple electrolysis experiment gave the kiddos a small window through which they could understand this process.

For another easy experiment with water, I encourage you to check out Ashley Mullen’s, Walking Water Experiment. Discover the colorful magic of capillary action.

A great book to get kids excited about chemistry is The Periodic Table: Elements with Style! The periodic table shows us the building blocks for every substance in the world. This book is written in a simple and humorous style with great illustrations. It is interesting to me as an adult and simple enough for beginning readers to read independently. 

Science concepts can be introduced early. With each exposure, students will gradually develop a greater understanding of how the world around them works.
