OK.And put some water right onto the salt.And you just keep doing it until something will happen.</p><p>Can you hear that, It's very high like a meee，and the light is on. What does it mean? </p><p>This means it must be raining outside. </p> <p>M：Let's do the experiment in another way. First we put two copper strips into fresh water，then put them into salt water，what difference between them? </p><p>B：In fresh water, the light up a little bit，but in salt water, the light is very bright. </p><p>M：So saltwater is a good conductor of electricity. </p> <p>M：What if we put two copper strips together?</p><p>B：Wow, the light is the brightest. </p><p>M：Do you know why? That's because the current forms a loop</p><p>So if you want the light on, how can you do?</p><p>B：Put the two copper strips together or put them into the salt water. </p><p>M：That's right. </p> <p>十一、Supplementary</p>
