Archimedes Principle Experiment – Part 1 We are going to drop marbles into the cylinder one at a :me. 1. What happens to water as we drop in marbles?
2. What two quan::es can we measure? (What two quan::es can change?) 3. What is your independent and dependent variable? 4. What units are we measuring for each variable? Ex: $ or minutes miles 5. What are the units of your rate of change? Ex: hour x y Conduct the experiment by crea:ng a simple table. Take an ini:al measurement. Then drop in one marble and take a new measurement. Record your data in the table. Repeat un:l you have used up all your marbles. 6. Does the data depict a func:onal rela:onship? In order to be a func:on each x value must have only one y value These are x y Not a x y func*ons x y func*on -‐1 5 because -‐1 5 -‐1 5 since each x -‐1 has a 3 3 y value 3 3 value has -‐1 5 only one y -‐1 0 of 5 and 4 -‐2 4 -‐2 value, 0 even if the points repeat. 7. What kind of correla:on does your data depict? Posi:ve Correla:on: as x increases, y increases Nega:ve Correla:on: as x increases, y decreases or as x decreases, y increases No Correla:on: neither above, no trend 8. What is the domain and range of your data? x y Domain: -‐3 12 [-‐3,-‐1,0,2,5] 9. Is two inches a reasonable domain value for your data? -‐1 10 Range: Jus:fy your answer. [12,10,9,7,3] 0 9 10. Is two inches a reasonable range value for your data? 2 7 Jus:fy your answer. 5
