How Many Elements Can You Name?

Just a quick ship today to part a quiz I of late wrote for my chemical scientific discipline class. It's a quiz to run across how many of the elements they already know earlier nosotros delve into our report of the periodic table.

I don't facial expression my students to hold upwardly able to refer all 118 elements. Hello, I can't fifty-fifty create that myself! But, I create desire to emphasize to my students that at that spot are 118 elements. The numbers are at that spot entirely for students to continue rails of how many they tin remember. They create non necessitate to know the atomic position out for each chemical gene as well as house it correctly. Though, perhaps the quiz could hold upwardly used for this after inwards the year???

Substances vs. Mixtures Sorting Activity

We're making tedious only certain progress inward chemistry. H5N1 few weeks ago, it came fourth dimension to larn to course of report matter. While looking through my reference textbooks for ideas, I ran across an persuasion inward the teacher's edition of Prentice Hall Chemistry.

Here's the persuasion inward master copy form:

Source: Prentice Hall Chemistry (Teacher's Edition) Page 50
 Instead of writing the words on index cards, I decided to type them.





I too made an response fundamental in addition to then I could proceed upward amongst which words belonged inward which column to a greater extent than easily.

I didn't just follow the instructions every bit just every bit printed inward the teacher's edition. I had ii volunteers record upward 1 in addition to 2 nether Category H5N1 in addition to three in addition to four nether Category B. When the degree couldn't arrive at upward one's heed on the categories, nosotros taped upward 5-8.


After to a greater extent than discussion, nosotros taped upward a few more. My students even in addition to then couldn't quite seat their finger on what to cite the ii categories, only they did seem to bring an persuasion of what types of things would belong inward each category. So, instead of telling the volunteers what category to house their cards in, I had the volunteers represent upward their cards to the class. The degree had to arrive at upward one's heed which category each bill of fare belonged in.


As they made their guesses, I verified using my trusty response fundamental in addition to clipboard!


Here's what our terminate production looked like:


My students were able to position that Category H5N1 alone contained elements in addition to compounds. However, they didn't know that these ii categories formed a larger category known every bit substances.  Category B had them puzzled, though. They could selection out what belonged there, only they couldn't hand it a name. Looking at particle diagrams of elements/compounds/mixtures helped arrive much clearer afterwards inward the unit.

Element Bingo

My chemical scientific discipline students are inwards the midst of taking weekly chemical component subdivision quizzes until nosotros convey the symbols of the outset 36 elements memorized. Influenza A virus subtype H5N1 couplet of weeks ago, nosotros played a few rounds of Element Bingo to laissez passer on them do remembering the symbols for each element.


Students were given a blank Element Bingo carte du jour (free download at the bottom of this post!) to hit sum out. There were 24 spaces on the bingo card, together with students had to select their elements from the outset 36 that nosotros were memorizing. Therefore, every pupil should convey dissimilar elements on their bingo carte du jour than their classmates.

Here's the blank bingo carte du jour they were given:

Not all of my students followed the directions to ONLY write the symbols on their bingo cards.  I approximate I require to emphasize this to a greater extent than adjacent time! The students who did write the names together with the symbols could nonetheless play bingo amongst us, but they didn't larn the do of trying to cry upward what symbol stood for which element.


It but together with thence happened that the twenty-four hours nosotros were scheduled to play this was the same twenty-four hours that one-half of our chemical scientific discipline flat was missing due to a softball tournament. We ended upward playing a few to a greater extent than rounds than I was planning on, but this worked out since I didn't desire to larn besides far ahead amongst one-half of my students missing!


My students took the game super seriously, together with they were trying their best to mean value of the symbol that corresponded to the chemical component subdivision called earlier checking their respond on the periodic tabular array or their written report guide. Magnesium together with Manganese were a tricky pair for my students to proceed straight. They also struggled amongst Neon together with Nitrogen.


I couldn't discovery my bingo chips when nosotros went to play this, together with thence I ended upward pouring a bag of pompoms (affiliate link) that I had bought for an action later on inwards the yr inwards a few beakers to gear upward or together with thence the room for students to role equally bingo playing pieces.


They LOVED this! And, I've decided that a beaker sum of pompoms is i of the cutest things I've e'er seen.


For the chemical component subdivision calling cards, I used a free download from STEM Sheets. I was able to specify just what I wanted on my bingo calling cards. I chose lift together with chemical component subdivision symbol, but I could also convey included atomic number, atomic mass, or solid pose down at STP. I was able to select the disclose to impress per page together with just which elements I wanted to print.


My students actually took to the bingo activity, together with thence I await frontwards to incorporating it to a greater extent than later on inwards the year. I run into a game of polyatomic ion bingo inwards our future!

Element Quiz Generator

I mentioned inwards a previous post, that I'm giving my chemical scientific discipline students weekly chemical factor quizzes until they convey the symbols too names of the commencement 36 elements memorized.

When I told my husband of my innovation to write my chemical factor quizzes, he offered to tending practise an Excel Spreadsheet that would automatically generate random chemical factor quizzes. Of course, I took him upward on his offer!

Here's the finished product:


Change the version letter, too the spreadsheet volition automatically generate a novel quiz. Not happy amongst the novel quiz version? Hit F9 to generate a dissimilar version.



This purpose of the spreadsheet controls the magic. 



Type inwards the atomic numbers that you lot desire to quiz students through. Choose a quiz discover too version letter. The spreadsheet does the rest. 

For my class, nosotros are doing 4 quizzes. 
Quiz 1 - Elements 1-12
Quiz ii - Elements 13-24
Quiz iii - Elements 25-36
Quiz 4 - Elements 1-36

The spreadsheet made it super slow to generate all of these quizzes (including FOUR versions of each) inwards a thing of minutes. I exactly hitting F9 until I got a quiz version I wanted, too then I selected "Microsoft Print to PDF" every bit my printer. 





Each PDF contains a quiz too the corresponding response key! 



 Here's what the finished production looks like:
