- The answer key had some mistakes, but now it has been fixed!
This lab uses the wonderful paperclip as a way to represent elements!
With this lab activity, students will first use the Power Point to start their 'lab write-up'. When the written portion of their lab is complete, students will break up into six groups rotating to different stations.
Each station has FOUR sandwich bags with different combinations of colored paperclips clipped together.
Based on which paperclips make up the combination, students must determine four things about it:
(1) The CHEMICAL FORMULA that represents the paperclip combination.
(2) Whether the paperclip combination is an Element, an Element that is also a Molecule, or a Compound/Molecule.
(3) The number of elements that make up the paperclip combination.
(4) The number of atoms that make up the paperclip combination.
Once the students have completed this lab, they'll surely have a clear understanding of how to read basic (only symbols and subscripts, without coefficients) chemical formulas.
The Power Point and write-up encourages students to better understand the scientific method and prepare for future grade levels in which writing up a lab is expected.
Paperclips and Plastic Baggies
In the lab, links are provided to find/buy the large and small paperclips that I use for this lab. A suggested setup guide for the paperclips is given also... of course, you can make your own combinations.
