Balancing Chemical Equations Activity – one of my long time favorite activities. Students will learn how to read formulas, count atoms, create and read chemical equations, and balance chemical equations using a hands on activity with color coded formulas cards.
Lesson Resources: Create one set of materials for each pair of students. Store in a large zip-top bag
This is a fun way to introduce the families of the periodic table and their properties. The students really enjoy watching the video clips from Periodic Table Videos and the experiments performed by the Chemistry Department at the University of Nottingham.
As a class, we found the location of each family, recorded the elements for each family, discussed their properties, color coded the periodic table, and discussed any patterns they noticed.
Google Slides (Public) – updated for 2016 with links to the YouTube videos to view an element in each family
Handout – (pdf) students take notes for each family and use this is a reference for further lessons
Periodic Table – (Updated 2016 pdf) I like to use this student version of the periodic table from Jefferson Lab for my 6th graders. I photocopy it double sided – one side stays blank while the other side is color coded. If students have binders with a clear pocket on the outside front, I ask that they place it there for quick reference and access.
This activity was featured on the following blog post: The Joy of Chemistry – A Unit in Photos a few years ago. You can read about how she used this lesson in her 3rd grade classroom as part of her Chemistry unit.
Below is a video about Sodium from Periodic Table Videos. They have a lot of great chemistry videos posted for free on their site, be sure to check them out!
Google Slides – students will learn how to find the number of energy levels (shells) for elements in periods 1 – 8 and the number of valence electrons in their outer shells using the periodic table. Updated (Public link)
I updated the Google Slides and worksheet for my lesson on drawing Bohr Diagrams. This lesson will walk your students through the basics on how to draw a Bohr Diagram for the first 20 elements on the periodic table. I also created a simple worksheet for students to record their drawings and do independent practice.
I used this lesson after we had already learned how to balance chemical equations using the hands on lesson I created and described below (also found on my Chemistry page):
Balancing Chemical Equations Activity – one of my long time favorite activities. Students will learn how to read formulas, count atoms, create and read chemical equations, and balance chemical equations using a hands on activity with color coded formulas:
We worked through the problems together and I called on students to first identify the chemical reaction and then balance the equation. After a few slides, they began to recognize the types of reactions quickly and had a good understanding of how to identify and balance the equations.
I recently used Tracy’s Bonding Basics 2010Activity (link) with my 6th graders as a guided lesson. We spent one day on Ionic Bonds, and the second day on Covalent Bonds. Students worked in pairs and practiced making Lewis Structures, finding Oxidation numbers, identifying elements as either Metals or Non-Metals, and determining what each element would do when bonding with another element.
Instead of candy, I used pennies as electrons along with the element cut outs she provides on her website. This was a great hands-on activity to have students ‘see’ how the atoms bond together, and after a few slides, they were able to quickly determine how each element would bond.
