APSC 100 Module 2

Introduction to Experimentation

WHY? – do an introduction to experimentation?

•Develop basic laboratory and data management skills

• Develop an ability to critically evaluate results (understanding of error analysis)

•Practice technical writing

•Introduce experimental design

•Reinforce basic physics and chemistry concepts

Manual page #1

APSC 100

Introduction to Experimentation

WHAT – you will need:

•Courseware manual - Introduction to Experimentation

•Lab notebook – A90 black science university notebook – to record work done in lab.

•‘Writer’s Choice’ - Margot Northey and Margaret Proctor

•goggles and lab coat for chemistry/chem eng labs- (you will not be allowed in the lab without them) Goggles must be the bookstore or Chemistry science stores variety (not the safety glasses)

Structure:

•Week 1: no labs - complete error propagation worksheet

•Weeks 2 and 3: Tutorial Labs

•Weeks 4-9: 3 Physics and 3 Chemistry Experiments

•Weeks 10-12: Project Experiments

Students work in pairs to collect data but individual analysis and hand-in Students work in pairs to collect data but individual analysis and hand-in work is required!work is required!

Manual page #1

Week 1: Error Propagation Worksheet

•Prepares you for the error analysis you will do in labs

•no lectures on this material

•Appendix 4 (Module 2 part of lab manual) tells you everything you need to know about doing the problems on the worksheet (including examples that are very similar to the ones on your worksheet)

•TO DO: READ appendix 4. Do the problems on the worksheet. Hand the worksheet in next Monday.

•Tutorial help available this week at time listed on the bottom of the worksheet. Come prepared!!!

Tutorial Labs: Weeks 2 and 3

•Tutorial Lab #1: (week 2) Data analysis and uncertainty-Look at three different methods for analysing data and determining error.

•Tutorial Lab #2 (week 3) Planning an Experiment-YOU design an experiment to determine the springconstant for a spring. A step-by-step design guide(manual Appendix 7) is provided to walk you through the experimental design procedure.

APSC 100

Introduction to Experimentation

•Choose from 10 project experiment topics in week 5

•Plan your experiment in week 10

•Do your experiment in week 11 (& week 12 if you need to)

•Write a formal report on your experiment (can be with your partner )

Physics Project Experiments•The Resistivity of Play-Doh•Kinetic Friction acting on a Hot Wheels Car•Efficiency of an Electric Motor•Viscosity of Motor Oils•Temperature Measurement with a Thermocouple

Chemistry Project Experiments•Analysis of Vitamin C in Orange Juice•Neutralizing Ability of Antacid Tablets•Determination of Iron in Groundwater•Determination of Nitrates in Streamwater•Design of a Heat Exchanger for an Industrial Process (Chem Eng)

You do all project work with your lab partner.Manual pages 125-148

APSC 100

Introduction to Experimentation ASSESSMENT AND MARKING

You must attend all lab periods and complete all formal reports/assignments. Attendance will be taken.

You will receive an N/C for APSC100 if you miss ANY lab or don’t hand the completed assignment/formal report in.

Complete the form on the website to request permission to make up a missed lab if you are sick or have a valid excuse.

This form will enable you to make up the lab with another section

If your partner is away sick then you can either do the lab on your own or join with another group.

ASSESSMENT AND GRADING

A grade is awarded (A, B, C, D) for each assignment/report.Your overall grade is a weighted average of individual marks.

WEIGHTING•error propagation worksheet 5%

•tutorial labs (2 of these): 8% each

•Formal lab reports (3 of these - labs 1,3,6) 16% each

•In-lab analysis work (3 of these - labs 2,4,5) 5% each

•project experiments (effort and formal report) 16% Manual pages 4-5

APSC 100

Introduction to Experimentation

How is it graded?

•half of the grade is based on your conveyed comprehension of the lab (description of concepts, data analysis, error analysis, etc.)

•half of the grade is based on presentation: written English, organization, data presentation, concise explanation, table and figure format –

Introduction to Experimentation

ASSESSMENT AND MARKING for formal reports

What do we expect in a formal report?

A typed, technical document that explains scientific principles,procedures and results rigorously and concisely, illustrating your understanding of the subject matter.

Manual pages 4-5, 75-91

Appendix 2 (Manual) contains•A guide to writing formal lab reports•A formal report example - page 83 (you can also download this from the web and use it as a template for your own formal reports)

APSC141 will cover basic report writing concepts and organization in the next 2 weeks.

The grading criteria (for A, B, etc) that the TA’s use is in the manual pg 5 – also see page 91 in the manual for the TA checklist.

Northey and Procter’s book – ‘Writer’s choice’ - has a chapter on report writing and also provides general writing tips

Academic dishonesty

THE PENALTY FOR COPYING ANY PART OF ANOTHER LAB REPORT IS TO REPEAT APSC100 NEXT YEAR.

This signed statement is needed on the front of all reports:“I verify that this formal report is my own individual work and has not been copied in whole or in part from another source (with the possible exception of equations and/or diagrams from the experimental descriptions on the APSC100 website). Furthermore, I have not and will not lend this report (electronic or hardcopy) to any other student, either now or in the future ”

COPYCHECKER WEBSITE: in addition to handing in a hardcopy of your formal reports, a copy must be sent to our copychecker website. The TAs will verify that the hardcopy and e-copy are the same before they mark your report. The copychecker stores your report in a database and compares it against all others to identify similarities.

Do not borrow a lab from anyone.

Do not lend your lab to anyone!!

IF YOU LEND YOUR LAB TO SOMEONE AND IT GETS COPIED, YOU CAN RECEIVE THE SAME PENALTIES AS IF YOU WERE THE STUDENT THAT COPIED IT.

Share your data with your partner in the lab, then write your reports completely independently with no interaction!!!

To avoid repeating APSC100:

APSC 100

Introduction to Experimentation

•Complete the error propagation worksheet and hand in at Stirling Hall by 3:00pm Monday next week

Tutorial help is available this week- bottom of the error worksheet for details (don’t wait for this, though - start ASAP!!)

•read pgs 8-17 (tutorial lab #1) before your tutorial lab next week

•Transfer students see me now or contact me later to sign up for a special “modified module 2” session which runs in the evenings next term

What should I do before next week?
