Instructional Ideas

• Integrate this lesson into an introductory chemistry unit in the upper-elementary or middle school grade levels
• Create laminated copies of the period of table of elements for students to use as a reference during chemistry lessons
• Use the pages for the "Molecule and Atom Book" as note-taking guides for a research assignment on different elements and compounds

Classroom Considerations

• Lesson requires LEGO®, which may need to be purchased if none are available in your classroom

Pros

• Includes a printable periodic table of elements to serve as a student reference during this lesson
• Worksheet supports students with identifying the chemical composition of different materials
• An answer key is provided for the included worksheet

Cons

• None
