1. TCAP Review Bell Work Apr 15, 2014  Take out a clean sheet of paper, and write your heading on it. Number your paper from 9 to 18, and begin right away. 9) C- _________ come from chemical __________ 10) C- chem reactions form new _________ 11) C- Cx3: _______ the capitals for _________ 12) C- chem reactions can HOPE ____, _____, ____, ______ 13) C- chem reacts can 3FPC _____, _____, _____, _______, ___ 14) C- Control experiments are for ______________ 15) C- Constants do not ________ 16) D- DMV: __________ = _________ divided by __________ 17) D- DMV to MVD: ______ = _______ x _________ 18) D- DMV to VDM : ________ = ________ divides _________ Bonus: Write the formula for VDM with the division dog house Press the right arrow button on your keyboard to advance through the presentation

2. TCAP Review  Before we review the answers from the bell work, let's do a quick verbal review of letters A and B. Science Quick 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 atmosphere A cids=hydronium ions Acids are 0 to 6.9 on the pH Scale The 1 st 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

3. 9) C- C= C, ____________come from _____________________. 10) C- _____________ form new ______________ 11) C- Cx3: ________ the capitals for ___________ 12) C- chem reactions HOPE (_____, _____, ____, _______ ) 13) C- chem reacts 3FPC (_____, ____, _____, __________, _____) 14) C- ________ experiments are for ____________ 15) C- __________ do not change 16) D- DMV _______ = _____ divided by _______ 17) D- DMV to MVD ____ = ______ x _______ 18) D- DMV to VDM _______ = ________ divides _______ Bonus: VDM formula: TCAP Review Science compoundschemical reactions chem reactions substances countcompounds heatodorpopexplode fizzlefoam flash precipitate color controlcomparison constants The A B Cs of 8 th grade science Here are the answers to the bell work Notes Density Mass Volume Mass Volume Density Volume Density Mass Volume = Density Mass

4. 9) C- 10) C- 11) C- 12) C- 13) C- 14) C- 15) C- 16) D- DMV: 17) D- DMV to MVD: 18) D- DMV to VDM: TCAP Review Science The A B Cs of 8 th grade science Let's try this with verbal prompts Notes

5. TCAP Review Copy the underlined text 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) Science The A B Cs of 8 th grade science Now let's copy some notes for letter E

6. 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 reaction  Each 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 Li Lithium 6.9 Science

7. 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 Notes SPI 0807.9.3 Elements and Compounds Science

8. 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 0807:12.2 Electromagnetism Notes Science  Adjusting the strength of an electromagnet 1) Use more electrical current 2) Use more coils of wire Battery Solenoid Iron core

9. 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 magnet or SPI 0807:12.1 Electromagnetic Induction Science The three devices below are called electrical generators

10. 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

11. 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) 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
