Instructional Ideas

• Use a KWL chart for halogens

Classroom Considerations

• Narrator pronounces many words with a British accent, which may confuse some American pupils
• Relies on prior knowledge of periods versus groups on the periodic table, valence electrons, and chemical bonding

Pros

• Lists each chemical reaction as it shows the interaction
• Short length helps maintain pupils' focus

Cons

• None
