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

TCAP Review Copy the underlined text Science Notes The A B Cs of 8th grade science Now let's copy some notes for letter E 19) E- Elements = the different types of atoms 20) E- Electromagnets-using electricity to make a magnet 21) E- Electromagnetic Induction-electricity from magnets 21) E- Electrons = negative charge 22) E- Electrons-located in electron shells (AKA: levels or orbitals)
SPI 0807.9.3 Elements and Compounds Science Notes • 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 reaction • Each individual element is a unique particle called an atom • So in other words… elements are the different types of atoms 3 Example: Lithium is an element. Here is one lithium atom Li Lithium 6.9
SPI 0807.9.3 Elements and Compounds Science Notes • More About Elements: • Elements’ chemical symbols always start with one capital letter • Can be followed by one or more lower case letters • Examples of Elements: • H = the element hydrogen • represents one hydrogen atom • Na = the element sodium • represents one sodium atom • Uub=the element ununbium • represents one ununbium atom
SPI 0807:12.2 Electromagnetism Notes 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. • Adjusting the strength of an electromagnet • 1) Use more electrical current • 2) Use more coils of wire Iron core Battery Solenoid
SPI 0807:12.1 Electromagnetic Induction Notes Science 21) E- Electromagnetic Induction-electricity from magnets • Magnets and a coil of wire (called a solenoid) can create electrical current • This process is called electromagnetic induction • The magnet has to move through (or around) the coil or The coil has to move through (or around) the magnet The three devices below are called electrical generators
Quick Review SPI 0807:12.1 Electromagnetic Induction Science The pictures below show electromagnet induction in action. Both of these devices are called electrical generators Picture 01 Picture 02 To increase the electrical current increase the movement speed
Science SPI 0807.9.1 Atoms Notes • 21) E- Electrons = negative charge • 22) E- Electrons-located in electron shells (AKA: levels or orbitals • All matter is made up of atoms • Atoms 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) Protons and neutrons are found inside the nucleus Electrons are found outside the nucleus in the electron cloud in energy levels
