Simple Molecules and Compounds for Middle School
This pdf. document contains three different practice pages on teaching students how to read the periodic table and recognize the different elements of simple compound molecules.
The first two pages are almost like a periodic table scavenger hunt. Then, the third page actually has them draw simple molecules. The first page is called Naming Compounds. On this page, students are given the formula. They must use their periodic table to look up the atomic symbols. Once they find the symbol, they record the atomic name. Then, they have to look at the formula again to figure out how many atoms of each element are included in the formula. The second page is a reversal of the first page. You give students the atomic name of the element, and they have to look up the symbols. They must also decide the number they goes after the letter. I always teach them how to read the periodic table before doing these practice pages. I also go over how molecules have no number after the element if there is only one atom of that element.
The third page is a practice page on drawing simple compounds and molecules. Students are given the compound formula. Then, they have to draw circle for each atom in the formula. They will color each different element a different color.
I teach sixth grade and I am trying to incorporate the NGSS this year. I think this lesson which might take you two days to complete hits the new standards for creating models of simple molecules and compounds. After I we practice drawing simple molecules, I have kids make them out of marshmallows and toothpicks. This lab is also available for purchase in my store. Thank you for viewing my products.
Middle School National Standard:
MS-PS1 –Develop models to describe atomic composition of simple molecules and extended structures.
