Lesson Review C-47 April 29-30: May 1-6  2003   Valuable Links 

"Kahmya (13) and Brianna (11)....grand daughters...are introduced to Electricity and Magnetism..below. One day in the near future, Kahmya will be graduating as an Electrical Engineer from some College.  See my prediction below...that is already coming true!!!! Man,  I am good, as I truly have God in my life!"   Cleophas McAlpin

 Skip to the Future 3/23/07  Mr. and Mr. Michael Gory have a child.....Enter Ryder! H

 Cassondra (16) ...A new student. We discussed parallelograms, and had a good time of it! Other students in attendance were Keyotta (just turned 18), Jarrell (16), Ke' Ontra, Keisha, Jamise (20), Cachet (19), Brittney (16), Cassandra (15), Charity (16), Cleasena (17)

Cassondra is a joy to tutor. She is intense and makes tutoring a lot of fun. Cassondra and I discussed Geometry Two: particularly that same old geometric figure, the parallelogram. We delved into the Theorems that should make the calculations concerning angle-side-angle or the side-angle-side theorems a little bit easier. At times, Cassondra became the tutor and worked problems before I could!

Some things to remember about parallelograms:

1. Opposing sides are parallel   2. Opposing angles are congruent or equal   3. When a line is cut by a transversal, the sum of the angles is equal to 180 degrees.  3. The sum of the angles in a triangle is equal to 180 degrees  4. When parallel lines cut a transversal and the distances between the lines are equal, any other transversal in the same plane will have distances cut that are of equal length   5. Do not be confused by the (y + 20) degrees for one angle and the (x degrees) for another; simply remember the rules above for calculating the other angles.

6( This seems to be the most difficult to see) In calculating the Side-Angle-Side congruency between two triangles, remember the diagonal is common between the two triangles and if the sides are of equal length in the two triangles, then the SAS Theorem is valid and the triangles are congruent.

 

April 30....More of the Same ...  Focus is on Kahmya and Brianna....below!

Homework assistance and an introduction to the World of Electricity and Electronics for the students.

It was time for analogies. One such analogy was between Water Flow and Electrical Current Flow. Kahmya and Brianna received this, my favorite lecture, while some of the other students watched. Brianna and Kahmya are 11 and 13-years of age, respectively, but they caught on to the comparison between water current and amperes. Their comprehension between water pressure and electrical pressure (volts) astounded some of the older students who had a bit of trouble with this analogy. Kahmya is a brilliant straight "A" student, and it is a joy to tutor such a gifted young lady.

Some of the students took turns at making the comparison between rust in a pipe that controls or stops the flow of water (resistance) and electrical resistance (ohms) in a circuit.

The students ended up with that old formula....E = IR. This formula is a basic electrical formula and was manipulated to find current (I), resistance (R) and voltage (E). Algebra came into use for some of the younger students, but they responded with understanding.

Kahmya and Brianna now have a concept of frequency, hertz, electrons, atoms, insulators, conductors, test leads, electronic measuring devices, circuit connections, schematics and a lot more! Kahmya constructed a project in our Radio Shack Electronics booklet (an electronic organ) and it worked perfectly.

Brianna made a project for a Science Fair at her school and I assisted her with it. It was a "hand battery". Brianna now knows that two dissimilar metals can produce electricity when connected together and hands are placed upon the two metals (copper and aluminum in her case). The voltage generated was approximately 0.70 volts! Brianna was amazed at the success of her project and she should receive an "A" for her project and her understanding of basic D.C (direct current) and A.C. (alternating current).

It is indeed a pleasure to teach such gifted students. Their interest and attention is truly motivational. There is a distinct probability that Brianna and Kahmya may someday head up the Los Angeles Department of Water and Power for the City of Los Angeles! They are being prepared to do just that!

May 6, 2003  Students in attendance....Cassondra, Ke'Ontra, Jarrell, Christopher, Keisha, Jamise

Cassondra and I worked on Geometry. We worked problems dealing with similar triangles. Ratio and proportion was the order of the day for similar triangles. We found sides when the dimensions of other sides were given. We also did a problem involving the Pythagorean Theorem.

Happy Birthday....Ke'Ontra...will be celebrated on this upcoming Thursday!!!!!!
