G7 Week 15 – S2

Thursday-Friday, May 24-25th

Today in scienceA, F, & G period students were asked to continue working on the four light challenges described below.

Challenge #1: Light maze elephant hunt (3 mirrors)
Challenge #2: Light at the end of the tunnel (1-3 mirrors)
Challenge #3: Light journey on A3 paper (4 mirrors)
Challenge #4: Light journey on A3 paper (6 mirrors, plus one crossing light beam)

Homework: Each of the successfully completed light challenges was issued a red elephant stamp on the paper. Any student not yet finished with all 4 light challenges should try their best to complete them before the start of Monday’s science class.

Wednesday, May 23rd

Today in scienceA & G period students were asked to solve two practice problems at the start of class. These problems can be seen below:

Question #1

Question #2

These problems were meant to help students see the mathematical and conceptual skills needed to solve the four light ray challenges issued by Dr. M. Class time was provided for students to work on–and get help with, if needed–all four of the challenges.

Challenge #1: Light maze elephant hunt (3 mirrors)
Challenge #2: Light at the end of the tunnel (1-3 mirrors)
Challenge #3: Light journey on A3 paper (4 mirrors)
Challenge #4: Light journey on A3 paper (6 mirrors, plus one crossing light beam)

Homework: Students were not given any homework tonight on account of the fact that paper copies of all persuasive business letters are due tomorrow, Thursday, May 24th. Students were also first asked last Friday to secure a Pringles can for an upcoming science activity.

Tuesday, May 22nd

Today in scienceA period students were asked to prove to Dr. M that they could use a protractor accurately by completing an eight question pre-test. After that, students were reminded of three rules that must be applied to light in most instances: 1) light travels in straight lines, 2) light reflects off of mirrors, and 3) the angle of incoming light is equal to the angle of outgoing light. They were asked to use these three rules–but also an example sketched by Dr. Merritt on the whiteboard (see below)–to try and ‘hunt’ an elephant with mirrors. [Please know that Dr. Merritt does not condone elephant hunting!]

Rule 1 – light must travel in straight lines, Rule 2 – light reflects off of mirrors, Rule 3 – the angle of incoming light is equal to the angle of outgoing light

Today in scienceF period students were asked to prove that they were skillful elephant hunters before taking on the challenge of sending light through a bent tunnel without hitting the sides. Much time was devoted to helping each calculate and measure the angles so as to make the beam of light travel in expected ways.

Homework: Unless they have work still to do on their persuasive business letter revisions (due Thursday), F period students do not have science homework tonight.

Monday, May 21st

Today in scienceA period students continued exploring basic color theory by using the RGB Calculator to reproduce–as accuracy as possible–the nine practice colors that can be seen at the very bottom/end of this linked document. Dr. M collected students’ attempts at the end of the class period.

Homework: Unless they have work still to do on their persuasive business letter revisions (due Thursday), A period students do not have science homework tonight.

F & G period students were asked to prove to Dr. M that they could use a protractor accurately by completing an eight question pre-test.

They were asked to use these three rules–but also an example sketched by Dr. Merritt on the whiteboard (see below)–to try and ‘hunt’ an elephant with mirrors. [Please know that Dr. Merritt does not condone elephant hunting!]

Rule 1 – light must travel in straight lines, Rule 2 – light reflects off of mirrors, Rule 3 – the angle of incoming light is equal to the angle of outgoing light

HomeworkF & G period students need to use their knowledge of light and angles to position all 3 of the lines on which they will place your mirrors for their Elephant hunt. F & G period students could also be working on their persuasive business letter revisions (due Thursday).
