Yes, you read that right, we’re making a battery out of a piece of fruit! While you may know that metals are a good conductor of electricity, in this Lemon Battery experiment, you’ll find out why as you conduct enough electricity to set off the buzzer. This kit includes everything you need to put what you’ve learned into practice (besides the lemon!). Following the step-by-step instructions in the Online Classroom, you’ll connect the copper and magnesium electrodes to the lemon and the buzzer and see what happens when the citric acid of the lemon releases the magnesium electrode’s electrons. Did you make the buzzer sound?

Lesson Preview

Why are metals good conductors of electricity? Find out in Lesson 2 as you build and experiment with two different types of batteries. Explore chemical reactions between metallic and non-metallic elements and learn about reactivity. Continue your understanding of chemistry concepts, building off what you learned about the periodic table in Lesson 1. These exciting experiments show you how different substances can conduct electricity and explain how chemical bonds make up all parts of our lives. Unlock a better understanding of the world around you through these hands-on experiments. Electric shocks not included!
