Ionic Formula Wordle

text: IONIC FORMULA WORDLE

I am always looking for little activities to fill those "dead spaces" during the school day like passing times, when some students finish early, or when there is not enough time before the bell to start the next activity. Whenhit the scene on Twitter, I would play it with classes during passing time. It was a wonderful class bonding activity as we worked together to formulate our five-letter guesses.

如果您不熟悉Wordle,每天都有一個新的5個字母的單詞來猜測。提交猜測後,五個字母轉為顏色,為您提供額外的線索,以幫助您的下一個猜測。如果一封信變灰,那麼該字母不是在這個詞。如果一個字母變為黃色,那麼該字母在這個詞中,但不是在那個特定位置。如果字母變為綠色,則該字母位於該字中以及該特定位置。目標是在6次猜測中成功猜出神秘詞。作為一堂課,學生辯論,說服和投票下一步猜測。他們會看到其他課程是否估計他們的神秘詞減少,並比較他們的灰色/黃色/綠色框網格(圖2)。這是一個巨大的大腦突破,促進了神話般的互動和話語。

While I loved playing Wordle, I wished it would help reinforce a chemistry topic. Teachers started sharing "knock-off" versions of Wordle online using Google Sheets. I was inspired to make one using ionic formulas. With the generous help of @ScottTeach on Twitter, we developed an Ionic Formula Chemistry Wordle using Google Sheets (). In this version of Wordle, students type in letters and numbers to make a five-character ionic formula (ie. CoCl2in Figure 1). The boxes change color to gray, yellow, or green for every guess. Students use the color feedback and their knowledge of cations, anions, polyatomic ions, and balancing charges to formulate their next ionic formula guess.

I feel this activity works best as a large group or class. First, I type in a number into cell A11 to randomly pick a mystery formula. Then I digitally project the Chemistry Wordle Google Sheet on my whiteboard in front of the class. Then the students negotiate and vote on a first guess. I type in their guess into the google sheet so they can get their colored tile feedback. This progress continues until they guess the ionic formula correctly or run out of guesses. If they run out of guesses, I highlight the Mystery Formula boxes and change the cell color to display the correct formula (that is hidden because it was typed in a white font color). On the board, I color in the gray/yellow/green tiles (Figure 2) similar to what is shared on social media for the other classes to see and compare themselves to. Alternatively, you can share a copy of the google sheet with your students using your preferred LMS (Google Classroom, Canvas, etc.). Due to the limitations of this google sheet, it is easy for students to cheat if done individually. The database of formulas sheet is hidden and can be unhidden by clicking "View" and then "Hidden Sheets." There you can view, edit, or add ionic formulas for your specific needs.

I hope you and your classes have as much fun with this Ionic Formula Chemistry Wordle as my classes do! It is a great class teambuilding activity with a chemistry twist! I witness a lot of great student discourse about ionic formulas as they solve these, which is a HUGE WIN in my book! A big shout out to @ScottTeach for helping a random teacher make a random idea on Twitter become reality!
