  1. First Semester Final Exam Review

    Slide 1 - First Semester Final Exam Review

    • 2014-2015
    • Mr. Weisenfeld
    • Get Ready to Take Notes!
  2. Inquiry A (INQA) Scientific Questions

    Slide 2 - Inquiry A (INQA) Scientific Questions

    • How does changing ___(MV)___ affect ___(RV)___?
    • MV = Manipulated Variable (you change)
    • RV=Responding Variable (you measure)
  3. INQA (Predictions)

    Slide 3 - INQA (Predictions)

    • If I increase / decrease my ___(MV)___
    • then my ___(RV)___ will increase / decrease
    • because ______.
  4. INQB Scientific Procedures

    Slide 4 - INQB Scientific Procedures

    • Gather materials
    • (what, where)
    • Label MV
    • (how much, when)
    • Keep CV
    • (constant, not changing)
    • Be Sure to Measure RV
    • (how)
    • Perform steps in order
    • (write down all steps in detail)
    • Record data in a table
    • (a table helps organize info.)
    • Repeat for reliability
  5. INQC Scientific Conclusions

    Slide 5 - INQC Scientific Conclusions

    • Repeat the Scientific Question
    • Brings your reader up to speed
    • Summarize Data
    • “When the MV increased / decreased the RV increased / decreased…”
    • “The largest value for the MV was…”
    • And what the value of the RV was
    • “The smallest value for the MV was…”
    • And what the value of the RV was
    • “Overall as the MV increased / decreased…”
    • What did the RV do?
    • “The scientific reason for this was…”
    • Is there a bigger scientific model, or concept or law or equation that explains the data?
  6. SYS1A Systems and Feedback

    Slide 6 - SYS1A Systems and Feedback

    • Inputs go into a system.
    • Outputs go out of a system.
    • An Equilibrium is a balance
    • Static Equilibrium: no inputs, no outputs, system doesn’t change
    • Dynamic Equilibrium: there are inputs, and outputs, and system stays in balance
    • Feedback is a system output going back to system input
    • Positive feedback (not good!) system gets out of control.
    • Negative feedback (is good!) system calms down
  7. PS1C Energy

    Slide 7 - PS1C Energy

    • There are different forms of energy
    • Kinetic, Potential
    • Mechanical, Chemical, Electrical
    • Energy can be Transferred or Transformed
    • If it doesn’t change form, it is transferred
    • If it does change form it is transformed
    • Potential Energy,
    • is mass in kilograms
    • is gravity,
    • is height in meters
    • Kinetic Energy,
    • is mass in kilograms
    • is velocity in meters/second (squared!)
    • Conservation of Energy
    • If energy is not lost to friction it is conserved
  8. Periodic Table:  The Elements

    Slide 8 - Periodic Table: The Elements

    • What is the name of this element?
    • What is the symbol for this element?
    • Atomic number?
    • Atomic weight/mass?
    • What group is this element in?
    • What period is this element in?
    • Is this element a
    • Metal?
    • Nonmetal?
    • Metalloid?
  9. Isotope Symbol

    Slide 10 - Isotope Symbol

    • What element is this?
    • How many protons does it have?
    • How many neutrons?
    • How many electrons?
    • Is this an ion?
    • Cation?
    • Anion?
    • Neutral?
    • What is an isotope?
    • Is this the common isotope for this element?
  10. Slide 11

    • Metals vs. Nonmetals vs. Metalloids
    • Where are metals located on periodic table?
    • Where are nonmetals located?
    • Which tend to give up electrons?
    • Which tend to grab electrons?
    • What is the most reactive nonmetal?
    • What is the most reactive metal?
    • What are properties of metals?
    • What are properties of nonmetals?
    • What are properties of metalloids?

    • Discovered the neutron
    • Atoms are small & indestructible
    • Discovered the electron
    • Proposed Law of Conservation of Mass
    • All substances are made of atoms
    • Electrons can jump between paths
    • Electrons form clouds around nucleus
  12. Protons, Neutrons and Electrons
