I will share the investigation with you as well. I have done this activity for a number of years. A hint for pulling in some geometry and keeping the parabola centered on the paper is to have them construct(fold) the perpendicular bisector of the line(directrix). You can later facilitate the discussion of axis of symmetry. Another extension is to have them use the actual wax paper as they are graphing their own parabolas from directrix/focus information--helps them get the left/right information correct. Also, you can have the students geometrically prove the length of the latus rectum(or at least, the connection) by using the rectangle created. Don't feel bad about not knowing all of the connections--that was how it has been taught for years--don't question what the teacher says, just memorize it. It is so exciting to see the connections. Been teaching 22 years and I'm still finding them. Did you know all parabolas are similar--geometrically so. Just figured that one out recently. Good luck this year!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1091979517567705761.post-12561540448495713072014-05-29T10:18:46.925-05:002014-05-29T10:18:46.925-05:00Yay!
