Rachel uses realia, a coloring activity, a large annotated periodic table and physical movement to help her students remember elements and identify patterns within the periodic table. These are all highly effective strategies for her predominently ELL class. Two additional activities are added to support learning - a powerpoint presentation and a graphic organizer for student notes.
When I introduce the material for this section I present a Periodic Table Powerpoint while students fill in a Notes Graphic Organizer and color in a Periodic Table. The Periodic Table I use is the same one from the California Standards Test.
I start the PowerPoint on Slide 3 with the history of the Periodic Table and have students only fill in a summary at the end of the slide.
I then go through each of the important parts of the Periodic Table including atomic number, atomic mass, symbol, groups, periods, transition metals, lanthanides, actinides, metals, non-metals, metalloids, and groups with special names.
When I go through properties of metals, non-metals, and metalloids I use various examples.
- When explaining metals I show students examples of malleable substances by holding up a sheet of lead or copper or aluminum foil, and ductile by holding up copper or lead wire. I also talk to students about how we use metal for pots when cooking and metals for wires in appliances,etc..
- For non-metals I talk abut brittle substances like on the "Got Milk" commercials when they show peoples bone's falling apart if they don't drink milk. I also refer to the insulation in houses or insulation for our clothes and how those are made of non-metals like cotton which is made of carbon, oxygen and hydrogen.
- Finally for metalloids I refer to Silicon Valley (and how its not silicone which is what lots of students think of) and how its called Silicon Valley because of all of the computer technology.
While I explain each of these concepts students fill in notes on their Graphic Organizer notes papers as well as fill in the concepts on their new "Pretty Periodic Table". On the PowerPoint I have pictures of how I want students to draw on their Periodic Table.
