Current Electricity

It was our second day of electric science, and today we focused on current electricity.

Flip on the television.  You just experienced current electricity.  Mind blown.

Current electricity is the flow of electrons, and it delivers energy to things such as lights, televisions, and computers.  Electricity requires a complete path, or circuit, to flow.  It's like a circle of energy.

Voltage is an important word to know when talking about current electricity.  Voltage is the amount of energy - or push - in the electrons flowing through a circuit.  For my experiments today, I used a 9 volt battery and a 3 volt battery.

Here's what I learned . . .

STICKY LIGHT

Materials:
LED
Magnet
3V button battery
Electrical tape

Methods:
1.  Slide the battery between the wires of the LED so the longer wire touches the positive terminal (marked with a +).
2.  Wrap electrical tape around the LED leads and the battery to form a firm connection and a complete circuit.  The LED light should be on.
3.  Hold a magnet over the positive terminal of the battery.
4.  Secure the battery on the magnet with electrical tape.
5.  Place the magnet light on the refrigerator or any metallic surface.

Hypothesis:
The electrons will travel travel around the circuit and give off energy at the light.

Observations:
2 ends of a wire connected to a light and connected to the positive and negative ends of a battery = simple circuit.

Conclusion:
I made a simple circuit with a wire and a battery.  The electrons were flowing in a circle to make the light glow.

Mom says:  Electrons travel from the negative side of the battery, through the wires, and around to the positive side of the battery.  As they travel around the circuit, they give off energy as light.

Ok.  That's all for science for a little while.  We are getting ready for Spring Break, so we will do our electromagnetic science after that.  My Mom says she has too much laundry to do another day of science experiments.
