Big Idea Electricity and magnetism are related effects that have many useful applications such as conversion to heat, motion, and sound. Guiding Questions 1.How do we know when we have a simple series circuit? 2.What happens when one component from a simple series circuit is removed? 3.How is the brightness of 2 or more light bulbs affected when they are connected in a simple series circuit?

Once again you search your backpacks for materials that might give you a brighter light. Your partner discovers more things that could help. He finds another bulb and another D-cell (battery). He also finds 2 wires, 2 bulb holders, and 2 battery holders. Yesterday you managed to light the bulb, but the light was not bright enough for you to see well inside the cave.

Think and talk about… Where are the hikers? What do they need? What additional materials did they find in their backpacks? What is the problem that needs to be solved?

Focus Question Write a question in your notebook that is related to the scenario and can be investigated. Your question should be correctly written; capital letter and ending punctuation. Your question should not be able to be answered with a yes or no. You do not need to have the same question as your group.

The light we have is not bright enough to see in the cave, so how can we connect the new materials to produce a brighter light? Class Focus Question

Simple Circuit Simple Series Circuit One pathwayComponents: Battery Wires Light Bulb Control circuit

Prediction I think if we connect the _________________________ ________________________________________ then _____________________________________________ because ______________________________________ _____________________________________________ What should I do with the extra wires, battery and light bulb?

Planning Control Circuit 1 D cell battery 1 light bulb2 wires Test 1 Test 2 Test 3 Leave this column blank. You will need it to record your observations.

Measuring Brightness Control Circuit 1 D cell battery 1 light bulb 2 wiresScore Test 1 Test 2 Test 3 3: Brighter than the control 2: Same as the control 1: less than the control 0: no light

Meaning Making Conference Did any circuit make a light that was brighter than the control circuit? Why do you think the light got brighter? Did any circuit make a light that was not as bright as the control circuit? Why do you think the light was more dim? How many pathways does a simple series circuit have for the electrons to choose?

Claims and Evidence I claim that… I know that…. I claim this because… I know this because….
