## TEJ3M/4M – Oct 22, 2014

REMINDERS:  PARENT TEACHER INTERVIEWS  ARE OCT 23 SO PLEASE TRY TO BOOK A TIME WITH ME ASAP.  PROGRESS REPORTS WERE GIVEN OUT ON FRI OCT 17.  STUDENTS ARE TO RETURN THE BOTTOM PORTION OF THE PROGRESS REPORT ASAP (SIGNED BY PARENTS IF YOU ARE LESS THAN 18 YEARS OLD).

The grade 12’s (TEJ4M) were to continue with their “race bots” using lego mindstorm.  They are to build a race car of their own design that will be timed in the hall for 30 tiles (the tiles equal to 30ft in length).  On Oct 14 I gave the students 3 resources to help them better understand “Gear Ratios” which will help them design a robot that will be fast.  The 3 resources can be found below.  The students  should have their robots completed and their 3 times recorded by tomorrow (Oct 23) before the end of the class.  The students should be completed their “race bots” and ready to work on the next activity.

I began the class today by showing the grade 11’s (TEJ3M) how to properly make a “simple circuit” using the breadboard trainer.  I had a student assist me while I did a live demo using the iPad on the digital projector.  I wanted to stress the fact that they should be using a resistor when making circuits using the LEDs (otherwise the LEDs will burn out or burst).  I then told the students that they were to make the 3 introductory circuits once they created a showed me a “simple circuit”.  The circuits they are to make on the breadboard trainer are: 1.) a series circuit; 2.) a parallel circuit; 3.) a series & parallel circuit.  I showed the students an example on the digital projector (I will post the examples below).  When the students complete each of these circuits, they are to call me over to take a picture of their circuit with the iPad.   Those students that complete the 3 introductory circuits above, are to complete the next 2 circuits.  These 2 circuits are: 4.) 3 Resistors & 3 LED’s; 5.) 7-Segment LED Display.  For the “3 Resistors & 3 LED’s”, the students have to calculate the resistance for each resistor using the resistance example I gave them a few weeks ago (you will find a copy of this below).  We will continue using the breadboard trainers at the start of tomorrow’s class.

Below you will find a copies of the handouts/worksheets that were distributed/assigned in today’s class.

A Simple Circuit Connected Properly Using Resistors on Breadboard Trainer (This is a screenshot from the live demo I did in class today using the iPad)

A Simple Circuit – Using the Breadboard Trainer (Example) (this is an example of a simple circuit using the breadboard trainer – TEJ3M only)

Examples using the Breadboard (Parallel, Series & Parallel Series Circuits) (I showed this to the students in class so they knew the expectations – TEJ3M only)

Examples using the Breadboard (3 Resistors & 3 LED’s and 7-Segment LED Display) (I showed this to the students in class so they knew the expectations – TEJ3M only)

Resistance Example (the students can use this example to help them calculate the resistance of each resistor they are using for the “3 Resistors & 3 LED’s” circuit – TEJ3M students only)
