Paper Plate Bohr Models

One of our primary goals inward physical scientific discipline is to recognize patterns inward the periodic tabular array based on valence electrons.  Before nosotros tin saltation to talking nearly valence electrons, nosotros starting fourth dimension demand to only acquire nearly the placement of electrons inward the atom.  After doing a foldable amongst lots of practise Bohr models, I assigned each pupil 1-2 elements.  We used newspaper plates, markers, too dot stickers (affiliate link) to brand newspaper plate bohr models for each of the starting fourth dimension twenty elements on the periodic table.  

Here's the event Hydrogen Bohr Model I made to exam out if this was fifty-fifty going to work: 


We used dark-green dot stickers (affiliate link) to stand upward for protons, xanthous dot stickers (affiliate link) to stand upward for neutrons, too ruby dot stickers (affiliate link) to stand upward for electrons.  Originally, I was going to possess got them set ii dark-green stickers to stand upward for ii protons, but thus I realized that when nosotros got to chemical cistron twenty it would decease WAY also much.  So, nosotros used 1 dark-green sticker for the protons, too nosotros wrote the break of protons on that dark-green sticker.  Same for the neutrons.  I had my students calculate the neutrons using the average atomic volume from the periodic table.  

I didn't possess got a pic of this phase of the project, but I had students describe their Bohr models on their dry out erase boards too possess got them checked BEFORE moving on to the newspaper plate phase of the project.  This helped clear upward approximately misconceptions nearly how to brand a Bohr model!  

As students finished their newspaper plate bohr models, I asked them to accommodate them on the flooring at the front end of the classroom every bit a periodic table.  Here's what it ended upward looking similar at the destination of the period.  The starting fourth dimension matter you'll in all probability honor is that at that spot are non twenty elements.  Some students did non complete inward the allotted time.  Also, 1 pupil only threw his plates on the ground, thus they are most definitely NOT inward the right spot.    





Special cheers to my husband for letting us borrow his compasses!  This projection is a definite keeper, too I expect frontward to edifice on it inward the hereafter if I acquire the take away chances to instruct physical scientific discipline again.

Some of the kids complained that their Bohr models weren't real pretty because at that spot is only SO much going on.  This makes the perfect lead-in to why we'll hold upward moving to electron point diagrams next!
