ClassX Video Lessons Youtube Channel Next Generation Science Lighthouse Lab – Circuits: Batteries Arranged in Series
Welcome to the lab! Today, we’re going to learn about circuits and how they work. We’ll start with a simple circuit, add a switch, and then see what happens when we add more batteries in a special way called “series.”
First, let’s make a simple circuit. We’ll need a light bulb in a holder, two wires with clips, and a battery in a holder. Here’s how we do it:
Now, the circuit is closed, which means electricity can flow all the way around, and the light bulb turns on!
To control the electricity, we can add a switch. A switch lets us open or close the circuit:
Now, let’s make things more exciting by adding another battery in series. What do you think will happen to the light bulb?
When we turn the switch on, the light bulb shines brighter! This is because adding batteries in series increases the voltage, which makes the light bulb glow more brightly.
Let’s try adding a third battery in series. What do you think will happen now?
With the switch on, the light bulb is even brighter! More batteries in series mean more voltage, making the light shine even more.
So, here’s what we learned today:
In our next adventure, we’ll explore what happens when we add more light bulbs to the circuit. See you next time in the lab!
Build Your Own Circuit: Gather some simple materials like a small flashlight bulb, a battery, and some aluminum foil to act as wires. Try to create your own circuit at home. Can you make the bulb light up? Experiment by adding a switch using a paperclip. What happens when you open and close the switch?
Battery Hunt: Look around your home for devices that use batteries. With an adult’s help, find out how many batteries each device uses. Are they arranged in series? Discuss with your family why some devices might need more batteries than others.
Draw and Predict: Draw a picture of a circuit with two batteries in series and a light bulb. Predict what will happen if you add a third battery. Share your drawing and prediction with a friend or family member and discuss your ideas.

Welcome back to the lab! Today, we’re making circuits. We’ll start by setting up a simple circuit, then we’ll add a switch, and finally, we’ll see how adding batteries in series affects the circuit.
Let’s set up my simple circuit. I’m going to use a light bulb in a holder, two wires with alligator clips, and a battery in a holder. First, I’ll connect one end of the battery to the light bulb using a wire, and then I’ll connect the other side of the light bulb to the other side of the battery. There you have it! The circuit is now closed, and there is a complete path for electric current to flow, which is why the bulb turns on.
To control the flow of electric current, we can add a switch to the circuit. When the switch is in the off position, the circuit is open, meaning no current can flow. But when we turn the switch to the on position, the light bulb turns on because the circuit is now closed.
Next, we’re going to add another battery in series to the circuit. What effect do you think this will have on the light bulb? Let’s find out!
Time to turn the switch on. Wow, the light turned on! This is because when you add two batteries in series, the voltage of the circuit increases, and the light shines even brighter.
Now, let’s add a third battery in series. What do you think it will do to the light bulb? Time to close the circuit. Wow, the light bulb is even brighter! This is because the three batteries connected in series increase the voltage even more.
So there you have it! A simple circuit consists of a light bulb, wires, and a battery. Adding a switch helps us control the flow of current to turn the light on and off, and adding batteries in series increases the voltage in the circuit, allowing the bulb to burn brighter.
In the next video, we’ll take a look at the effect of adding bulbs in series. Until then, see you next time in the lab!
