Ramp: Forces and Motion

  • Predict, qualitatively, how an external force will affect the speed and direction of an object's motion.
  • Explain the effects with the help of a free body diagram.
  • Use free body diagrams to draw position, velocity, acceleration and force graphs and vice versa.
  • Explain how the graphs relate to one another.
  • Given a scenario or a graph, sketch all four graphs.

pH Scale

Outcomes:

  • Determine if a liquid is acidic, basic, or neutral
  • Place acids or bases in relative order
  • Describe on a molecular scale, with illustrations, how the water equilibrium varies with pH
  • Determine concentration of hydroxide, hydronium and water at a given pH
  • Relate liquid color to pH
  • Predict (qualitatively and quantitatively) how dilution and volume will affect the pH and concentration of hydroxide, hydronium and water
