Welcome, everyone! Today, we'll start with the basics of electrical conductors. Can anyone tell me what a conductor is?

Exactly! Good job, Student_1. Conductors, like metals such as copper, let electric current pass through easily. Now, what would you call materials that do not conduct electricity well?

Right! Insulators include materials like rubber and plastic. Remember, knowing the difference is crucial for safety. You shouldn't touch electrical devices with wet hands because water can conduct electricity. Let's try a memory aid: 'Water's a shocking conductor, so keep it away from the electrical structure!'

Yes! We'll learn how to use a tester to experiment with different liquids next.

Now that we know what conductors and insulators are, who wants to help me test if some liquids conduct electricity?

We’ll use a tester! Let's start with lemon juice. Can anyone guess if lemon juice will conduct electricity?

Good reasoning, Student_2! Now let’s dip the tester into the lemon juice. Does the bulb glow?

That means lemon juice is a good conductor. Now, what about distilled water? What do we think?

Let’s test it out. Remember, most substances must have ions to conduct electricity.

When we pass an electric current through a conducting solution, something interesting happens. Can anyone predict what it might be?

Exactly, Student_4! Gas bubbles might form at the electrodes. This is one of the chemical effects of electric current. Let's recall William Nicholson's experiment with water—what did he discover about gas production?

Right! This indicates a chemical change due to the current. Remember to connect the idea of chemical reactions to the concept of electroplating.

Yes! That's exactly what electroplating is. You've all grasped a lot today!
