I updated my Dunkin’ for DensityLesson for 2016, I use this lesson with my 6th graders as part of our unit on properties of matter. I wanted it to be more data driven and have them analyze the data from all of their trials, and then compare their data to their classmates. I changed the objective to:
Change the density of the film canister so that 90-99% of the canister is suspending under water.
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.
This is a fun activity to get students thinking about the properties of acids and bases based on their prior knowledge. Then using what they know, can they figure out the rest of the properties?
I like to do this activity as a friendly competition and see how many each pair of students can answer correctly. Before the students place items into the Venn diagram, I ask them to look at the properties and write a red “A” next to the property if they think it belongs to an acid, a blue “B” if they think it belongs to bases, and “AB” if it belongs to both categories.
Once they have completed categorizing the properties on their own, have each student share their answers with their seat partner. What was the same? What was different? Have them discuss their reasoning for each answer and try to come to a consensus. (You can add an additional step by asking partners to compare answers with another set of partners.) When they are ready, reveal each answer, one at a time, and discuss. Students will write (or glue in) each property into the Venn diagram.

I use this activity as an introduction to my minerals and mining unit. Students learn the 5 properties of minerals (SNIFC) and apply them to a variety of items to categorize each item as either a mineral or non-mineral.
I also have the slides in a pdf format if you would like to have the students sort the items first, then discuss each item and why they think it is or isn’t a mineral. Then, they can view the answers afterwards.
