I feel like I'm running around in circles as I teach about circles! LOL
Math 9
Circles, Tangents and Chords, OH MY!
Geometry, I find you either hate it or love it. We will be learning a few properties of circles this week to coincide with the following objective in the Saskatchwan Grade 9 Math Curriculum:
Outcome: SS9.1
Demonstrate understanding of circle properties including: - perpendicular line segments from the centre of a circle to a chord bisect the chord
- inscribed angles subtended by the same arc have the same measure
- the measure of a central angle is twice the measure of an inscribed angle subtending the same arc
- tangents to a circle are perpendicular to the radius ending at the point of tangency.

Presentation to Judges
On the day of the science fair, you
will be approached a number of times by a judge or group of judges who are
excited to see what you did your project on.
Follow this outline in order to give a proper presentation:
1) Smile and
introduce your self and shake hands with the judge(s)
After this point the judges will ask
you to tell them about your project. At
this point you will be required to give a presentation that lasts around 3-5
minutes
The presentation will require you to
tell the judges a variety of things regarding your project. You can either use your backboard as a guide
or use cue cards. DO NOT STARE AT YOUR
BACK BOARD AND READ IT WORD FOR WORD!
Present in the following way.
2) State
your title to the judges and tell them how you came up with the idea
(introduction)
3) Discuss
your main question (purpose) and what you believed your findings would be
(hypothesis)
4) Explain
the research you did to begin answering your question (background
information). Use statements like: “I
did some research on ____________ and I found out that ___________.” If you did a study, this section will make up
the majority of your presentation and you will not include step 5.
5) Discuss
how you set up your experiment or innovation. (procedure)
6) Explain
your findings by referring to your observations and data collected. (data and
observations and conclusion) Make sure you refer to any charts, graphs, or
photos you have to back up your results.
7) Explain
how your project is significant to the world we live in and the people in
society (significance) and discuss anything that may have gone wrong (sources
of error)
8) feel free
to add in any other interesting or important pieces of information that you
think the judges would like to know.
At the end of your presentation, the
judge(s) will often ask a few questions to either clarify something about your
project or to find out further information.
If you truly put in a good effort and worked hard, you will know the
answer to these questions. In the case
that you DO NOT know the answer DO NOT TRY TO MAKE UP AN ANSWER! When you are asked a question you are unsure
of just be honest and let the judge(s) know that you are not sure what the
answer to that question is.
Please read over this document and
feel comfortable with it. Plan out your
presentation in advance so you are ready for the day of the fair. Be confident and ready to let everyone know
about the great work you did!
