6th Grade Physical Science (S1: Waves E5: Bot Mobile)
S1E5: BOT-MOBILE CONTENTS
MISSION OBJECTIVES
At the end of this cattle drive all cowpokes will be able to use dimensional analysis to convert units.
After a few practice laps all pit crew members will be able to summarize the relationship between wave velocity, frequency, period and wavelength.
After completing flight school all viper pilots will demonstrate what they’ve learned about wave properties by making transverse battle rope waves and calculating average frequency, period and wave velocity.
By the end of this campaign each Granger-2 clan member will be able to summarize what happens to wave velocity, period, frequency and wavelength as various quanties change up and down. I have spoken.
BASIC THEORY
Wave velocity through a medium is equal to frequency times wavelength, and wavelength divided by period.
Frequency and period are reciprocals. As one goes up, the other goes down. If one doesn’t change, the other doesn’t change.
Changing wave properties like period, or frequency have no effect on the wave’s velocity thru the medium. Only properties of the medium can do that. Things like linear mass density, and elasticity in a rope, or temperature in air.

RESEARCH (See KB-23’s Wonder Time for more)
During competition L.E. said she might be asked to create a first harmonic standing wave. What is meant by harmonic? What’s a standing wave?
L.E. mentioned in the last lesson that the height she moves her hands will be less than the amplitude of the battle rope wave due to something called resonance. What is the physics definition of resonance? Look up the Tacoma Narrows Bridge and watch a video of it’s destruction due to resonance.
S1:E5 BOT-MOBILE CONTENTS BY SECTION
COMIC INTRO
See K-2L5 and KB-23 sneak the Bot-Mobile down to the North Wilkesboro Speedway for some suspension testing and a few left hand turns.
KB-23’s WONDER TIME
Put your ear to the wall and measure your “freak” in hertz. Watch the Tacoma Narrows Bridge turn into a giant wave. Find out how waves stand.
PROF E’s LEARNING TIME
Prof E explains the wave equation to the bots using his NASCAR analogy. The bots try it out by turning laps at the North Wilkesboro Speedway. Everyone sings, “The Bot-Mobile, re-peat-edly, Showed wave velocity, is wavelength over T. She’s a rope wave maker...”
K-2L5’s PRACTICE TIME
Make slinky transverse waves. Measure period and frequency. Calculate wave velocity. Do the same with first and second harmonic slinky standing transverse waves.
MISS TONKS’ SHOW ME TIME
The bots take the Bot-Mobile to the Bristol Motor Speedway then mosey on down to North Wilkesboro to compare the Bot-Mobile’s performance at different tracks. KB-23 learns some secrets about L.E.’s tardis alarm clock.
L.E.’s REFLECTION TIME
Reflect on what you’ve learned, and create some questions for the class in the ship’s holo space while the bots pull some hard yaka shearing alpacas. Can you say, Grounded!
GRANGER-2 BAND’s VOCAB TO LYRICS
Record definitions for all the new terminology you’ve learned. Create a “Weird Al” type song. Try changing the lyrics to “Rope Wave Maker”. [Note: Juke Box Hero was one of Prof E’s favorite songs during middle school.]
ATMO’s ANSWERS
All the adults, and bots are out for the day. Review answers to Miss Tonks’ questions. Boring! Then join Atmo on the hanger deck for a game of fetch.
RAINBOW FIVE’s SNEAK PREVIEW
Drop Rainbow Five a line--litterally, ha! Find out what happens in the next episode. She knows. She was just named the oh-fish-ial betta of the Science-lete Games. Wooo!
Two separate formats are included.
The "Spread" version shows what the lesson would look like if presented in comic book format, one two-page 11 x 17 spread at a time. It's great for displaying electronically, or for printing full two page spreads on 11 x 17 paper.
The "non-spread" version depicts each page on 8.5 x 11. It's great for printing back to back pages which will then allow the story to unfold like turning pages in a book.
