🧪 Reaction Claims Mini-Clinic

Teams revisit the fuel system and material claims already chosen for their car using teacher-modeled examples, particle diagrams, balanced equations, and simple calculation checks. Students use anchor charts, periodic tables, molecular model pieces, and class notes to verify that their reaction model, bonding explanation, and environmental claim are scientifically defensible before revising the prototype. Younger students can sort picture cards and explain orally; older students complete labeled reaction and composition checks.
