1. Science Electricity: Lesson 8: How a Bulb Works Day 1

2. The BIG Question: How is current electricity produced?

3. something must touch the positive and negative terminal of the battery something must touch the threaded base and the tip of the bulb current electricity can only flow from negative to positive + + + + electricity needs a complete circle in order to flow

4. yes Will the bulb light? no yes X X X X X

5. My Prior Knowledge 1-2 All About Atoms 3-4 How is Static Electricity Produced? 5 Electrifying Vocabulary 6-8 How Electrical Charges Affect One Another 9-10 How is Current Electricity Produced? 11-16 Will the Bulb Light? 17

6. something must touch the positive and negative terminal of the battery something must touch the threaded base and the tip of the bulb electricity needs a complete circle in order to flow current electricity can only flow from negative to positive

7. How are the parts of a light bulb important for making it light?

8. Draw a picture of a light bulb and label the parts.
