Energy Flow in an Electrical Circuit

Energy Flow in an Electrical Circuit Worksheet (Grade 6 Science, TEKS 6.8B)

Follow the energy through a simple circuit. This one-page reading and activity sheet shows a battery, wires, and a bulb, with an energy flow chart from chemical energy to electrical energy to light and thermal energy. Simple numbers show that the energy coming out of a bulb always adds up to the energy going in.

What's Inside

• A Big Question box: "How does energy move through an electrical circuit?"
• A circuit doodle, an energy flow chart, and a short example with 100 units of energy
• Activity 1: Students complete the energy flow for a flashlight with a word bank
• Activity 2: Students find how much energy becomes thermal energy in an old-style bulb and an LED bulb
• A visual answer key with answers marked in red

How Teachers Use It

Use it before a circuits lab or as practice for TEKS 6.8B. The sheet takes about 10 minutes, needs no prior knowledge, and prints clearly in black and white.

This worksheet is part of the Reading in Science series for grade 6. It supports TEKS 6.8B: describe how energy is conserved through transfers and transformations in systems such as electrical circuits, food webs, amusement park rides, or photosynthesis. It is one of seven connected TEKS 6.8B sheets that follow energy through systems. The unit big idea is that energy can be stored, transferred, and transformed, but it is not created or destroyed.

Why It Works

Each sheet opens with a Big Question, teaches the key terms in plain words with simple black-and-white doodles, and then asks students to use only what the page taught. Simple whole-number energy units make conservation visible, and the visual answer key lets teachers check work fast.
