Texas Essential Knowledge and Skills for Science

Teacher's field guide

What Students Need to Do: Students compare a model with the real object it represents. They tell how the model helps and what differs because of its size, features, or material.
What Mastery Looks Like: A student can explain that a toy animal shows body parts but is smaller and cannot move like a real animal. The student points to details as evidence.
Common Misconceptions: Students may think a model must look exactly like the real object, or that every small copy is accurate. They may overlook differences in texture, movement, inside parts, or scale.
How to Assess It: Show a plastic toy elephant and a photo of a real elephant. Ask students to name one helpful feature of the model and one thing it cannot show.

Lesson moves

Give pairs a toy car and real car photos, then sort sticky notes under “helps us see” and “does not show.”
Ask, “How is a globe helpful, and what can it not show?” Record one class answer for each question.
Play Model Match by pairing object cards with model cards, then naming one helpful feature and one difference.
Examine a school evacuation map and walk the hallway, noting what the map shows well and what it leaves out.
