Pollination & Pollinator Decline

CONCEPTUAL

Science›Ecosystems & Habitats|Ages 11—12|ID: mt_wWpa5fFDZP

Explain the importance of insect pollination for plant reproduction and human food security, and discuss the consequences of pollinator decline

Mastery Evidence

Explains why many food crops depend on insect pollination to produce fruit and seeds
Names examples of crops that require insect pollination (e.g. apples, almonds, oilseed rape)
Discusses the potential impact of bee population decline on food production
Connects to plant reproduction — flowers are adapted to attract specific pollinators

Assessment Prompt

“If [child] saw a news story about bees dying out, could they explain what that would actually mean for the food in your kitchen — which foods would be affected and why?”
