FREE Build an Atom Activity with a Hole Punch and Glue
Build an atom using circles from a hole punch! This is a great way for students to visualize the electron energy levels of the Bohr atom model and a great way for students to practice reading chemical symbols!
Each page has a chemical symbol and a bare atom with a nucleus and energy levels (with dotted lines). Students paste in colored circles for neutrons, electrons, and protons! You can pick whatever color paper you want and just use a hole puncher to make a ton of circles.
This activity requires the following materials:
3 different color paper
A 3 hole puncher
Glue sticks for each of your students.
You can use Pages 1-40 which have the chemical symbols for first 20 elements plus a variation of each (an isotope or an ion)
You can use Page 41 which is blank. You can then assign each student the desired chemical symbol you want them to use to fill out their diagram. I included this option, because I know some teachers don’t have the ability to print out 40 pages but can print one page and make 40 (or more) copies!
Use the 3 hole puncher to create colored circles and pick one color to be electrons, one to be protons, and one to be neutrons. Then tell your students which colors symbolize which subatomic particle and have them glue their circles to their Bohr atomic model.
When you assign students their pages, I recommend giving students matching pages. For example, you could give student A pages 1a and 1b, because that student will see the difference between two different ions or isotopes of the same atom.
You could copy them back to back to reduce paper, but a great way to use these would be to make 40 (or 20 if you want to just use the atom versions) individual poster like pages! After your students complete them, you could hang them in a line around the room to show the atom models from hydrogen to calcium.
