Draw the EDD and data table for the following experiment:

• Students wanted to test the effect of time of submersion (under water) on the height that water would rise in a paper towel strip. They cut a 4cm strip of paper towel and then submerged it into a glass of water that was 5 cm deep.

After 10 seconds, the water had risen 11mm.After 15 seconds the water had risen 14mmAfter 20 seconds the water was still at 14mm.After 25 seconds the water rose to 15mmAfter 30 seconds the water rose to 16mm

EDD• Title: The effect of the submersion time on

the height of the water• Hypothesis: If the submersion time is longer,

then the height the water rises will be higher.• IV: Submersion Time (sec)• Levels –

• DV: Height water rose (mm)• Constants – paper towel, size of strip, glass of

water

Questions

• What is the graph missing??• Where does the IV go?• Where does the DV go??• How to determine the interval for the x and y

axis?? It must remain even for the graph to be an accurate representation of the data!

• Take the high #- low # = range• Range/# of squares = interval
