Presentation Transcript

### Day 7

Ms. Milliner

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
• 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?
• We will discuss as a class; Be prepared to share
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
• 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
• 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
