A conductor is something that let’s heat and electricity go through it.
Example: Think of a hot summer day. You set on a shiny metal slide. OUCH! It’s incredibly hot and burns the back of your legs.
An insulator is something that DOES NOT let heat and electricity go through it easily.
Example: If you slide down a plastic slide like on some playgrounds, it will feel warm but not burn you. Plastic is an insulator.
Electrons are negative charges that circle the nucleus of an atom. They can flow in
a current through conductors and produce electricity.
• Today we won’t be using switches. Instead, we will use the following:1) a battery holder2) 3 wires with alligator clips on the ends3) 1 bulb and bulb holder
Conductor and Insulator Lab
1. Material Managers come and get your baskets. Do not touch the items until told to do so.
3. Put your name on your lab sheet.
Conductor and Insulator Lab
1. Glue your Electrical Energy Notes on page 11 of your ISN.
2. Material Managers come and get your baskets. Do not touch the items until told to do so.
3. Put your name on your lab sheet. Let’s read over it.
5. On your lab sheet, DRAW TWO DIAGRAMS , showing the circuit when you are testing a CONDUCTOR and a circuit when you are testing and INSULATOR.
On page 10, write a paragraph explaining what you learned about conductors and insulators today.
