PLEASE NOTE! This POTU is ONLY assigned to the GREEN class! It is due for the green class on April 11th!
Step Right Up!
How would it feel to climb a flight of stairs if every step was a little higher or lower than the previous one? The constant measure for treads and risers on most stairs keeps you from tripping. Have you noticed that the stairs outside some public buildings slow you down to a “ceremonial” pace? Or that little-used stairs to a cellar seem dangerously steep? Investigate the standards for stairs in various architectural settings and learn the reasons for their various slopes.
Your project should include:
Tread-and-riser data and slope calculations for several different stairways.
The building codes or recommended standards in your area for home stairways. Is a range of slopes permitted? When are landings or railings required?
Scale drawings for at least three different stairways.
After you’ve done your research, consider this question: Does a spiral staircase have a constant slope?
POTU #4 Write-up:
Problem Statement: In your own words, describe what is being asked of you.
Process and Conclusions: Explain, in detail, the steps that you took to find your data (include sources) and arrive at your data. Include the requested drawings. Any photographs that you have taken should be included in this section. Address the questions being asked in the project.
Evaluation: standard evaluation write-up.

This is a great question!
what do you mean by "Scale drawings for at least three different stairways"? Does it mean that it has to be drawn to scale?
that's exactly what it means. I recommend using graph paper for this part as well. Measure three different stairwells and record the data on three separate sheets of graph paper.
but wouldnt that require a bunch of graph papers for one stairwell (because a stairwell is quite large)?
can we draw the stairwall not drawn to scale? but in similar porportion sizes?
all you need is about three or four steps to get an idea of the staircase. Just make sure these four stairs are accurate and to scale with your collected data.
what do you mean 'to scale'? what if one of the stairs is like one feet? would we have to draw the one feet stair on the graph paper? or can we mini size/shrink it so that four stairs can fit in the graph paper?
to scale means that you can shrink it but it must stay in proportion. For example, if one box is 6 inches, then a one foot stair would be how many boxes on paper?
ooo i get it! so a one foot stair would be two boxes [in this case]
thanks XD
how should we graph the slope?
the length by width of each stair case? i know its the rise over run which is the tread and the riser. which is it? how should we graph it?
graph the stairs and then you will see that the slope can be drawn through the point of the stairs.
yes but, are we suppose to graph it like.... what goes on the x and y axis- the length on the y axis and the width on the x axis?
what do you think? how do you graph a staircase? how would you label it?
ok that makes it clear... (teheheee)... ok i got it

can we give the project to you at the end of the school day?
I would prefer it handed in during class.
what if we cant access a printer?
print it in school
