Day 7

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
