🐙 Marine Invertebrates Bundle | Dichotomous Key & Classification Lab (Grades 6–8)

Bring marine biology to life with this complete 2-day lesson bundle! Students first explore how marine invertebrates are grouped based on observable traits, then apply their understanding using a structured dichotomous key.

Designed for middle school, this bundle builds classification, critical thinking, and evidence-based reasoning through realistic scientific visuals and scaffolded activities.
