To be able to grade you objectively I will use the rubric below:
Summary of criteria:
- topic presentation (50 points)
- demonstration (30 points)
- teamwork (20 points)
I will randomly pick two members each from the other groups to rate you as well. 50% of the rating will come from me, and the remaining half from the rating of your classmates.
Take note that you will be graded as a team. The presenters' ratings for the topic presentation will be averaged to get the overall rating.
All members of each group must be present every meeting. Number of absentees per meeting multiplied by two will be subtracted from your presentation score. Here is a sample computation:
Overall rating (topic, demonstration, teamwork) = 90 points
Number of absentees in class in a single meeting = 4 (x 2) = 8 points
Final Rating = 90 - 8 = 82 / 100
================================================
Someone asked me about the Power of Sound, here is it:
When something vibrates in the air is moving back and forth it creates wave of pressure. These waves spread like ripples from pebble tossed into a still pool and when it reaches the eardrums, the change of pressure or vibration is experienced as sound.
Acoustics is the branch of physics that studies sound. Sound pressure levels are measured in decibels (db); a decibel measurement is actually the ratio between a chosen reference point on a logarithmic scale and the level that is actually experienced.
