Welcome to PHYS 106 Fall 2014 Bruce Palmquist

9/24/14 Blindfold navigation Science Update podcast: Frugal Engineering Introduce the course, course website and each other Brief introduction to the science notebook Blindfold navigation Discussion Homework: Motion Pretest, Describing Motion Verbally with Distance and Displacement, read associated sections of The Physics Classroom (TPC)

Learning Objectives for the Day Use proper terminology and accurate directions to guide a classmate from point A to point B. Using everyday language, describe how to determine whether an object has uniform motion

Blindfold navigation This is your first Table of contents entry. The format is as follows. Always use the date and title of the first class slide. Table of Contents Activity title (Date)………….Page Blindfold navigation (9/24/14)…………………..1 For this activity today, you’ll start by answering questions on your own, then discussing them with your group, then with the class. All notes, activities, brainstorming should be done in your quadrille notebook.

Blindfold navigation One person per group will leave the room for 10 minutes. Brainstorm methods of directing a blindfolded person from the starting point to the ending point without touching an obstacle. Write your directions in your notebook. Your directions will be read by another group so write clearly. No other directions are allowed. Only what is in your notebook will be read to your blindfolded classmate! Let’s guide a blindfolded classmate! Discuss

Blindfold navigation comments

Blindfold navigation, Bruce’s observations Different people have different foot sizes or step sizes Directions such as “make a quarter turn” can be interpreted differently by different people Scientists need a standard way to measure distances and time. NIST, National Institute of Standards and Technology We also need to come to agreement on our understanding of motion.

The Physics Classroom This is our (free) online textbook for the quarter. Most of your homework assignments will be worksheets from The Physics Classroom. If you miss class, you may print out the worksheet from the website and bring it the day it is due. Homework is listed on the first slide and on the weekly assignment sheets. Typically, the relevant reading assignments will be listed on the top of the assigned worksheet(s). They are listed as URLs such as http://www.physicsclassroom.com/Class/1DKin/U1L1c.html
