Make sure to do the analysis from your sowbug race lab. You made a data table of time...displacement...and distance sowbug actually travelled. Do the average velocity for the whole displacement. Make sure to have a direction with it. Do the average speed for the entire distance travelled. Do a graph of the displacement over the whole trip. Do a graph of the displacement over the whole trip. .................................................................... Do average velocity for each segment using displacement data. Do average speeds for each segment using the distance data. ..................................................................... Graph the velocities for each interval(from displacement data). Do a second graph of speeds for each interval using the average speed for each interval (from distance data). Questions: 1. Which is faster?...the speed of the bug or the velocity of the bug? Show calculations for each and, explain why! 2. Which interval gave the fastest speed of the bug? Show calculations and explain why. 3. At which intervals is the organism moving at a constant speed? What is the evidence for this from at least two graphs? 4. In which intervals is the organism moving at a negative acceleration? Show calculations and evidence from a graph. 5.In which intervals is the organism moving at the greatest positive acceleration? Show calculations and evidence from a graph.

No homework tonight other than to review the work we did in class today. I will be at a conference for Thursday and Friday. I left a few packets based on interpreting graphs and motion. the last one has five parts and comes with a rubric. It requires a lot of work to complete and get an advanced score. Do your best to finish these in the next two days. It is not a quiz so you may use resources to answer the questions.

oct 8

Study for a quiz on problems presented today on scale and actual.

oct 3

check out the velocity acceleration keynote presentation in student resources and do the questions at the end. There is also a formula sheet as well. Also finish the questions from last night doing the 5 step process.

oct 2

Make sure to do the homework in student resources : ez motion problems. Don't forget to double check your work...or 'rats' (true story). Great job participating in class today!!!!! 21 virtual Mario gold coins for everyone that participated.

Oct 1

View the powerpoint on distance, displacement, speed and velocity. Know these terms (including frame of reference). Know how to add and subtract displacements. Know your 3-4-5 right triangle combinations. Know the different formulas for d=vt
