TCAP Review
Before we review the answers from the bell work, let's do a quick verbal review of letters A and B.
ScienceQuick Review
1) A- 2) A- 3) A- 4) A- 5) B- 6) B- 7) B- 8) B-
Argon is the third most common gas in our atmosphereAcids=hydronium ionsAcids are 0 to 6.9 on the pH ScaleThe 1st letter is A, so the 1st numbers are A for acids Bases=hyrdroxide ionsBases are 7.1 to 14 on the pH ScaleB is for bigger (pH scale) numbers & B is for basesB tastes bitter and B is for blue color

Science
The A B Cs of 8th grade science
Now let's copy some notes for letter E
Notes SPI 0807.9.3 Elements and Compounds
19) E- Elements= the different types of atoms an element is a substance that CANNOT be broken down into a simpler substance by CHEMICAL means. You CANNOT change an element into a different element with a chemical reactionEach individual element is a unique particle called an atom So in other words… elements are the different types of atoms
Example:Lithium is an element.Here is one lithium atom
3
LiLithium
6.9
Science
More About Elements: Elements’ chemical symbols always start with one capital letterCan be followed by one or more lower case letters
Examples of Elements: H = the element hydrogenrepresents one hydrogen atomNa = the element sodiumrepresents one sodium atomUub=the element ununbiumrepresents one ununbium atom
Notes SPI 0807.9.3 Elements and Compounds Science
20) E- Electromagnets-using electricity to make a magnet
Electromagnet: a wire wrapped around an iron core connected to a source of electricity (like a battery)
Electromagnets: can be turned on and off as needed.
SPI 0807:12.2ElectromagnetismNotes Science
Adjusting the strength of an electromagnet1) Use more electrical current2) Use more coils of wire
Battery
Solenoid
Iron core
Notes
21) E- Electromagnetic Induction-electricity from magnets
This process is called electromagnetic induction
Magnets and a coil of wire (called a solenoid) can create electrical current
The magnet has to move through (or around) the coil
The coil has to move through (or around) the magnetor
SPI 0807:12.1 Electromagnetic Induction Science
The three devices below are called electrical generators
Quick Review
SPI 0807:12.1 Electromagnetic Induction
The pictures below show electromagnet induction in action.
To increase the electrical current increase the movement speed
Picture 01 Picture 02
Both of these devices are called electrical generators
Science
Notes21) E- Electrons = negative charge22) E- Electrons-located in electron shells (AKA: levels or orbitalsAll matter is made up of atomsAtoms are made of 3 sub-atomic particles……protons (are the blue circles) (pos charge)…neutrons (are the green circles) (no charge)…electrons (are the orange circles) (neg charge)
SPI 0807.9.1 Atoms
Protons and neutrons are found inside the nucleus
Science
Electrons are found outside the nucleus in the electron cloud in energy levels
