Fourth grade is exploring with electricity. Last week we learned what causes the crackle of lightning and how the buildup of negative charges on your clothing can cause a shock.
In addition, we learned some safety tips to deal with electrical energy as well as the types of insulators used to protect the conductors.
After assembling a flashlight, we discovered the positive and negative sides of a dry cell work together to make appliances, radios and even cars run.
Next we created a series circuit. Although the "s" in series may indicate more than one in a series circuit, there is only one path for the electricity to flow.
We expanded our series circuit to a parallel circuit, a circuit that has more than one path for electricity to flow.
Finally, we arranged our wires, bulbs and dry cell to power our bulbs.
Lastly, we brainstormed ways where we could make the bulbs flow brighter.
The students suggested adding another dry cell. Their theory was tested and success was ours!
