TEJ3M/4M – Oct 30, 2014

There were still some grade 11’s (TEJ3M) that were making the 3 introductory circuits from last week.  I put the students into groups a few days ago to mix those students that were ahead with those that are a little behind.  The introductory circuits they are to make on the breadboard trainer were: 1.) a series circuit; 2.) a parallel circuit; 3.) a series & parallel circuit.  I showed the students examples a few weeks ago on the digital projector for all 3 of these circuits.  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 3 circuits.  These 3 circuits are: 4.) 3 Resistors & 3 LED’s; 5.) 7-Segment LED Display; 6.) double 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).  For the 7 segment LED, the students have to make the number 8 and for the double 7 segment LED, the students have to spell the word “hi”.  Once the students have completed all of the above circuits, they to work on the assignment titled “555 Timer Assignment”.  I gave the students a worksheet showing them where they needed to connect certain components and then showed the students a video that I took of a circuit one of my students made last year using the 555 Timer Chip (students also need a capacitor, wires and resistors which I showed the students in class).

The grade 12’s (TEJ4M) were to continue using the lego mindstorm robots.  I went over briefly the documents titled “Lego NXT robots using NXC tutorial – Part 1, Part 2 and Part 3” with the students on the digital projector.  I told the students to read through these documents because there are detailed notes about the programming that they need to know for the next few activities.  The students were to first build the “Explorer Bot” which I gave the students step by step instructions for (students can make modifications to the instructions if they are missing pieces or would like to do their own design).  After going over the tutorials, I then told the students to finish making their “Explorer Bot”.  The first task the students have to complete before moving on is to have their robot go straight until he reaches a wall or an object (using the touch sensor) and then the robot is to reverse and then go left.  The students are to put this into an infinite loop so that it always reverses and then turns left when it runs into something.

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

Explorer – Step By Step (the students only had a chance to start building this robot in class today – TEJ4M only)

Lego NXT robots using NXC tutorial – Part 1 (this is the coding examples for the “Bricx Command Centre” software – The TEJ4M students only)

Lego NXT robots using NXC tutorial – Part 2 (this is the coding examples for the “Bricx Command Centre” software – The TEJ4M students only)

Lego NXT robots using NXC tutorial – Part 3 (this is the coding examples for the “Bricx Command Centre” software – The TEJ4M students only)

Groups for the Electricity Unit (these are the groups I made up for the electricity unit – TEJ3M only)

Example of 7 Segment LED & Double 7 Segment LED (I did this example in class today on the white board to help those students that are ahead do the 7 segment LED and double 7 segment LED – TEJ3M only)

Example of the double 7 Segment LED (I showed the students this example today  in class using the breadboard trainer on the digital projector to help the students – 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)

Oct 30 – 555 Timer Assignment (I showed the students a video in-class to help the students see a visual example for this assignment.  A copy of this video can be found in the hand-out folder on the school network)
