Unit 1 goal: to develop basic typing skills while using proper posture and hand position.
Lesson 1: diagnostic assessment
The Jabberwocky: Read aloud – act it out
Provide basic definitions and show that there are multiple definitions for some of the nonsense words (ex: brillig: 2:00pm or twilight?)
Part 2: Students hand write the poem. This is to help them associate and process new and challenging words. Provides diagnostic assessment to help teacher identify students lacking basic skills and in need of remediation.
Important note: After the typing unit is completed, we move on to typing the Jabberwocky poem in a Google doc (unfortunate but this is a free application, even though it is unreliable, does not update consistently and carries only the most basic features and has severely limited (and marginally used) fonts.
Lesson 2: sign on to typing.com – students may use their school gmail accounts to sign in.
Student assessment is based on number of unit tasks completed.warn students not play the games because the typing.com ganmes are not instructional (hacking note: typing.com appears to be a copy and paste plaguerized copy of Mavis Teaches typing including the finger illustrations. However, the did not copy the instructive games – probably could find the js – o dropped in some peck and hack space invader type video games – make sure students avoid these as they are not instructive.
Videos: I’ve been trying out short videos as APK with mixed success. HEre’s one I think the kids like…
This is an Excel project intended for you to learn how to use Excel as a calculating tool, and to learn to “Chart” or graph your results.
This project will help prepare you for college where you will have to do numeric analysis to solve various problems. When you work in engineering, you will frequently have to build numeric models and present the results in chart form.
Use your “Small Angle Approximation CBQ” as a starting point.
Create a spreadsheet for angles 0.00, 0.01 ….. 0.09, 0.10, 0.20 …….0.80 radians
Create columns for Θ in radians, Sin Θ, Θ -Sin Θ,% error [Θ -Sin Θ %], Tan Θ, Θ -Tan Θ, % error [Θ -Tan Θ],
Create a scatter plot for % error vs Θ
Submit electronically to my email, prior to next class (email@example.com).
CBQ: Create a table with 3 columns (Θ, SinΘ , Tan Θ). Set your calculator to radians.
Calculate SinΘ , Tan Θ for;
Θ = 0, 0.01, 0.03, 0.05, 0.07, 0.10, 0.20 …..0.80.
Show that Θ ≅ SinΘ ≅ Tan Θ for 0 ≤ Θ ≤ 0.80
By what % do Sin and Tan diverge at 0.80 radians?
Convert 0.80 radians to degrees.
A glass fibre has an index of refraction of n1 = 1.5. Assume the cladding of the fibre has an index of n2 = 1.0.
A] Using Snell’s Law, derive the equation for total internal reflection (often called the critical angle).
B] Solve the equation for the maximum angle as measured from the fibre optic axis which satisfies total internal reflection.
In this post, I included the lecture notes for a development of Snell’s Law (1621) using a Huygen’s Wavelet construction (c. 1670). Special case: Total Internal Reflection leads to a 10 minute mini lecture on optical fibres, T1 cables, repeaters and IR wavelength demultiplexing. Finish Reading: Refraction

CBQ:PE and KE
Acrobat Art of mass m stands on the left end of a seesaw. Acrobat Bart of mass M jumps from a height h onto the right end of the seesaw, thus propelling Art into the air.
Art’s mass is 40 kg, Bart’s mass is 70 kg, and the height of Bart’s initial jump is 4 meters.
A] How high is Art propelled?
B] How fast is Art moving just before he lands?
S – V – S (sketch, define variables, solve)
Start the lesson with a quick CBQ. The CBQ is a question from the Ch 15 Study Guide which was assigned over Spring Break.
CBQ:The speed of sound at room temperature (20 C) is 343 m/s. If the speed of sound in air increases 0.60 m/s for every 1 degree C increase in temperature, what is the temperature when the speed of sound is 353 m/s ?
ans: ch 15 study guide section 1 #13 ans: 37 C

CBQ 3: The first problem is more difficult. Using the thrust burn time and mass of the Falcon 9 reusable rocket’s 2nd stage, calculate the its velocity after a second stage boost phase burn.
Less challenging: A diver pushes SpongeBobSquarePants with a force of F= 1,000 N for 10 seconds. SpongeBob’s mass is 1 kg. What is SpongeBob’s momentum after the push? What is his velocity? (hint: use the impulse – momentum theorem).
Ft = delta p = mv
v = Ft/m = (1,000 N)(10 s) / (1 kg)
medium deifficulty problem: 2 skaters, he – 80kg, 4 m/s, she – 40kg, 8 m/s
she jumps in his arms and they travel off together — find their velocity.
(80)(4) + (40)(8) = (80+40) vfinal
vfinal = 640/120 = 5.33m/s
Please note: Physics Unit Plan needs to be updated to include U4: Impulse – Momentum, Theorem
