👩‍🏫 Teacher’s Guide

Objective
Students will explain how chemical energy is stored in substances and released through chemical reactions.

Vocabulary
energy, potential, kinetic, heat, conductor, insulator, circuit, reaction

Teaching Notes

• Begin with demonstrations (rolling ball, battery circuit, melting ice, or candle burning).
• Define vocabulary terms and relate to visible phenomena.
• Explain how all energy forms connect and transform into one another.
• Encourage hands-on experiments and student predictions.

🧒 Student Worksheet

Concept and Helping Material

Definition. Energy takes many forms and can move or change from one type to another. Motion, heat, and light are examples of energy in action.
Helping ideas and samples:

• Compare stored and moving energy.
• Draw arrows showing energy changes in an example system.
• Identify evidence that energy is moving or transforming.

Vocabulary and Definition

• — stored energy due to position or condition
• — energy of motion
• — total motion of particles in matter
• — energy of moving electric charges
• — energy stored in substances released during reactions
• — transfer of heat by contact
• — material that slows or stops energy flow
• — a complete path for electric current
