To help plan for the creation of your level you must create a beat chart - this is an individual task - so one each.
A Beat Sheet is the "road map" for the LEVEL so all the various elements that will make-up the playing experience.
This is an important document so try to do the following:
Providing context for your response the headers - so if it is set at night, why is it set at night.
Include concept art to illustrate your ideas.
Be specific - what shades of colour to produce what effect? What is the tempo and tone of the music and why?
PUT EFFORT AND CARE INTO THE PRESENTATION - produce it in Word or Pages to make use of their formatting tools, then upload to your blog.
FINISH FOR HOMEWORK.
