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.

9 Supplies for Today Person A: paper towel two pieces of clay Person B: Box 2 batteries 2 battery holders 2 wires 1 piece of nichrome wire piece of paper clip

10 1A. Place 1 battery in a battery holder.

11 2B. Use a paper clip to connect this battery holder to a second battery holder.

12

13 2B. Use a paper clip to connect this battery holder to a second battery holder.

14 3A and B. Attach one wire to the other end of each battery holder.

15 4A. Knead each piece of clay to make it soft. 5A. Place one piece of clay in the center of your paper towel.

16 6A. Push your two wires into the clay so they are about a pinky width apart.

17 7A. Push the second piece of clay down on top of the wires to hold them in place.

18 8B. Wrap the nichrome wire around the top of your two wires so that it is pulled tightly between them.

19 9B. Place the second battery in the holder. Make sure your batteries are connected from negative to positive!

20 How are the parts of a light bulb important for making it light? Draw a picture of a light bulb and label the parts. Draw a picture of your light bulb model.
