My Very Educated Mother Just Served Us Nine Pizza! - saying to help you remember the order of the planets from the sun.

M - Mercury       - inner planet
V - Venus            - inner planet
E - Earth             - inner planet
M - Mars            - inner planet
(Separated by an asteroid belt - asteroids are minor planets that also orbit the Sun)

J - Jupiter          - outer planet
S - Saturn          - outer planet
U - Uranus (Ernus)    - outer planet
N - Neptune             - outer planet
P - Pluto                       - outer planet

On switch circuit!
Picture
Off switch circuit!
Picture
Off switch - electrons can not flow through the switch becuase there is a gap since the switch is left up.  This is what stops the elctrons from flowing through the circuit and causes the bulb to not light up.
Picture
On Switch -  electrons can flow through the switch because there is no gap.  This is what allows the light bulb to turn on.

1.) What is current electricity?
2) Know the difference between series and parrallel circuits (review anchor charts below).
3) Is a series or parrallel circuit better? Explain why.
4)Review how to attach a circuit and make a light bulb light up. Know how to draw the circuit using proper symbols (anchor chart below).
5) What are conductors and insulators? (Conductors - all aboard "Whoo hoo", Insulators - stops electron flow, "oh no you didn't")

Metalic items are conductors becuase they allow electrons to flow through. However if there is rubber over the metal then the item will be an insulator, since rubber is an insulator.

6) Current electricity can be transformed into four different energy outputs, sound, light, mechanical and heat. Review the anchor below and know what type of energy output is provided by different devices (e.g, lamp = heat energy, CD player = sound energy etc.,) Remember to choose the main one.

Series circuits are connected in a chain like order.  If one bulb breaks it affects the other light bulb. This is what they used to use for Christmas lights.  Remember how frustrating it was if one light didn't work?
Picture
Parallel circuits are connected individually and allow for electrons to flow to all parts of the device. This allows for all lights to work even if one doesn't. Good thing they started making Christmas lights using parallel circuits!

Potato Clock! 10/05/2011

Did you know that you can power a clock by using a potato? The potato acts like a battery and powers the clock. If you want to know more read below.


An electrochemical battery stores chemical energy that changes into electrical energy that runs electronic equipment. There is a chemical reaction within the potato battery that causes the electrons to move. The electromotive force within each potato is the ability it carries to move electric current. In an electrochemical cell, such as the potato battery, the copper wire makes the electrons move in the potato, causing energy to move into the clock.

The official scientific name for the chemical reaction is "redox reaction." The process starts when one side of the battery loses electrons. This happens in the zinc nail, which forms the anode, or positive part of the circuit. The zinc in the nail reacts with phosphoric acid in the potato, releasing electrons. The zinc loses two electrons while the copper in the wire reacts with the phosphoric acid to release hydrogen ions, which gain the electrons. This is the negative half of the circuit, or the cathode, which thereby gains the electrons.

    Current Electricity - flow of electrons through a medium, can be turned off or on.

Current electricity is tranformed into various energies depending on the electrical device.

The following are the four energy transformation.
1) Light
2) Heat
3) Sound
4) Mechanical

    Here is an anchor chart to show what happens when a balloon is rubbed against your hair.  It takes the electrons( negative) from the hair and now since it has more electrons it retains a negative charge, while the hair is positive. Negative charges and positive charges attract each other, while similar charges repel.  This is why the hair sticks to the balloon (static electricity).
    The electrons are "stolen" through the act of rubbing the balloon against the hair (static electricity).
    Each nucleus (positive charge) has a electron (negative charge) that circles around it. The negative electrons are held closely to the nucleus because the nucleus is postive (opposite charges attract).

- Opposites charges attract
- Similar charges repel

Atoms are made up of three things:
1) Nuetrons (nucleus)
2) Protons (positive charge, located in the nucleus)
3) Electrons (negative charge)
