How+to+measure+velocities

Protista - Measuring Motion
Velocity is a measure of the amount of distance traveled in a time. To find a relatively accurate velocity for the Protista, we will be using several samples.


 * Step 1.** From an amalgamation image, calculate the total distance traveled by adding up the distances for each segment. __Show your work__ for YOUR group's amalgamation:


 * Total distance** = d1 + d2 + d3 + d4 (use all your distances, this is just an example)


 * Step 2**. Calculate velocity. Show your work:


 * average velocity** = total distance / time


 * Step 3.** Record the velocity for each amalgamation. Determine the average velocity for each protist by repeating Step 1 and 2 for the best 8 amalgamations from among all the classes.


 * || Volvox velocity (μm/s) || Paramecium velocity (μm/s) ||
 * Trial 1 ||  ||   ||
 * Trial 2 ||  ||   ||
 * Trial 3 ||  ||   ||
 * Trial 4 ||  ||   ||
 * Trial 5 ||  ||   ||
 * Trial 6 ||  ||   ||
 * Trial 7 ||  ||   ||
 * Trial 8 ||  ||   ||
 * Average ||  ||   ||

Using the above data and your observations, rank order the Protists from fastest to slowest by name.
 * Step 4:** View samples of all 4 organism videos.


 * 1) Fastest
 * 2) __Second fastest__
 * 3) Slower
 * 4) __Slowest__

List at least 2 sources of error which might occur in using this method of determining rate and how the procedure(s) could be made more accurate if you were to repeat it. 1.
