Naming binary compounds is such an important fundamental skill to know to be successful in chemistry. I have tried various methods in engaging my students in mastering the skill through having a naming race where students name as many as fast as they can, to using charged ion pieces to show the bonding ratios. Recently, I purchased a budget 3-D printer for home use (since I don’t have one in my classroom), and got started tinkering and designing various objects. Upon stumbling on an old Boggle game, I decided to create some dice with elements on them and create a compound naming game in the form of the original Boggle.The benefits of a 3-D printer is that it allows you to print whatever you can create. I used Tinkercad to make the tray, box, and the dice. I have also used www.thingiverse.com to visit other ideas and samples for other 3D objects. In the future, an extension of the Chemistry Boggle game can be for the students to create their own dice with elements of their choosing. The skills of 3D designing, measuring, and printing an object provide and capture a lot of skills that are beyond the curriculum.
The Chemistry Boggle game is similar but not exactly identical to the original Boggle game. The game has 12 dices, and contains dice that are not only 6-sided but with some that are 12 sided. The different dice consists of elements in its ionic form, and also elements with their full names. The objective of the game is to create as many compounds, either formula or the compound name, as many as you can within a time limit. Unlike the original Boggle game, the compounds do not have to be formed with the dice that are beside or touching each other. You are basically forming as many compounds as possible with all the available ions or elements in the 12 wells. The time limit can be set according to the level of the students. I have used 1 min to 5 mins, and have found 3 mins to be a happy number to maintain a level of competition. Once the round is complete, the students compare answers with each other. Any answer that is a repeat will not get a score. In other words, if I say “Potassium oxide”, and if all the other students have it, it will not be counted. If only 2 of the 4 students got it, then those 2 students will get the point while the others will not. Essentially, a score is provided to those who have an unique answer. To encourage a collaborative effort between the students, I have the students verify each others answers. If a student says “iron oxide”, another student should question, “is it iron(II) or iron (III)?” and double check the spelling of their compound names. After each round, the students tally their scores, and can play 3-4 rounds to determine the winner of the game. A tournament style can be used as well where scores of the best 2 from each group is placed into the finals group where they compete for the winner.
