Bohr Model Activity

Today we created Bohr models using tennis balls, golf balls and students.  Bohr models are used in order to model different elements.  We practiced making the elements at least Hydrogen through Boron as well as some ions and isotopes as well.  From the activity, I wanted students to see the correlation between the Group # and the # of valence electrons as well as the Period # equal to the number of shells the element had.  Once done with this activity, we had a worksheet that just reinforces using the periodic table.  Tomorrow we will have a paper to review what we did with Bohr models.

Ions and Isotopes...Oh My!

Can you guess from the title of this post what we did in class today?  We learned about ions and isotopes!  We viewed the Brainpop videos for each topic, then completed a "cheat sheet" to help us remember the differences between them.  Lastly, we had a worksheet to complete over the topic.  All of the links are below.
