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 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 (bweissbard@boscotech.edu).

]]>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] 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.

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?

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
