Day 7

Ms. Milliner

warm up
Warm-Up
  • Turn to a new page, DATE THE PAGE, and then COPY DOWN the following
  • For your exam, you should be able to:
    • Define all terms from Warm-Up 1/31/12
    • Identify independent/dependent variables, controls
    • Draw a correct graph if given data
      • Which axis is the independent variable graphed on
      • Which axis the dependent variable graphed on
      • What information should it include?
      • Is the graph linear or nonlinear?
    • Identify which ball/car will bounce/return higher if given slope/measurement
    • State the outcome of each lab in words/by graph (direct/indirect; linear/nonlinear)
data analysis
Data Analysis
  • Create graphs in your notebook
  • Copy your graphs on a whiteboard
  • Write a conclusion for the mass lab from 1/31/12
    • What are the numbers/graph telling you in WORDS?
    • What type of relationship do you have? Linear? Non-linear?
    • Was your hypothesis correct?
  • We will discuss as a class; Be prepared to share
concept application
Concept Application
  • If we were to calculate a slope for our data, what would it tell us? Would it be positive or negative? Explain using your data.
  • Suppose you attached a 2nd car and repeated the lab. What do you think making the car heavier would do to your data?
  • Create 3 examples of inverse relationships with a partner.
  • How would the return distance for a car that has a mass of 300 g compare to a car that has a mass of 100 g? Which returns more?
class discussion
Class Discussion
  • What did you learn from yesterday’s lab?
  • How did this lab differ from the lab we did yesterday?
  • Are all relationships linear?
  • How do you think we could determine an equation or a best fit line for our graph from today (take a guess)
identification practice
Identification practice
  • In each example, identify: independent variable, dependent variable, control (if any)
    • You want to measure who listens to music for the longest time each day between teenagers and their parents?
    • You want to measure if a classroom noisier when the teacher leaves the room?
    • You want to measure (in min) how fast a candle burns?
    • You want to measure if heating a cup of water allows it to dissolve more sugar?
    • You want to measure the number of jobs students have by grade
