Description

Are your students confused about terms like actin, myosin, cross-bridges, troponin, and tropomyosin? Not anymore! Students use inexpensive materials to create a working model of sliding filament muscle contractions.

Teacher resources, student pages, and a step-by-step muscle contraction explanation is provided.

PLEASE NOTE: This resource is part of my Muscular System Unit and my Full Anatomy & Physiology Curriculum.

Included in this resource:

• 1 teacher instruction page with teaching tips and materials list
• 1 student page with directions and a background image for modeling
• 1 print-and-cut molecule page for use with models
• 10-slide PowerPoint presentation providing an explanation and illustration of each step of the muscle contraction process

This activity addresses NGSS HS-LS1-2.
