Let's predict first. (Remember, predictions can be wrong. It doesn't matter!)

1. Set up a circuit with one battery and ONE bulb.

2. Take a photo and upload it here.

What did you observe? Did the brightness of the bulb change when you added one BULB in SERIES?

Do a flashcard: What happens when I add bulbs to a circuit in series?

1. Add a bulb to the set up in series.

2. The circuit should now have one battery and TWO bulbs.

3. Take a photo and upload it here.

You want to find out how the brightness of the bulb will change when you add BULBS in PARALLEL.

We need to do an experiment to find out!

1. Upload the experiment you designed (include information such as materials needed, steps to follow)

2. Predict what you will observe. Give a reason for your prediction.

# data[].attributes.body
As you can see,set up one and set up two has different bulbs in each set up.Set up one glows dimmer then set up two because it needs more energy to light up three bulbs!

MATERIALS

5 light bulbs 5 wires 2 batteries

HOW TO MAKE SET UP

Connect the wires and light bulbs together and it will lit up!

# data[].attributes.body
When we add bulbs in series than the light gets dimmer.

# data[].attributes.body
How would you set up the experiment for it to be a fair test?

What do you need to keep the same?

What do you need to change?

Take a picture of your result(s) and upload it here!

Marterials needed wires ,battery,bulb and switch

Parallel electrical curcuit

Just click the switch

Material 2 bulb,2 battery,wire

Materials wires,bulb,battery

First, clip the wire to the battery then clip it to the bulb then the bulb will light up.

Materials for this set up is wire,battery,bulb.My predictions is that the light will get dimmer

# data[].attributes.body
Materiel for this set up is .wires.battery.bulb.my predictions is that the more bulbs the dimmer is will get.

# data[].attributes.body
When we do in parallel it is the same thing as series but different drawing when there is 1 batteries and two bulbs it will still got dimmer

Materials needed:

1 batteries

2 bulbs

# data[].attributes.body
Click the 3 dot button and select edit post and your done😄👍

# data[].attributes.body
What I will observe:

The bulb will get dimmer as the bulb doesn’t have enough batteries to brighten the two bulbs. Therefore, you do need to put two batteries to brighten the two bulbs.

Materials:

1 battery

2 bulbs

1 battery holder

2 bulb holders

2 wires
