  1. APSC 100 Module 2 Introduction to Experimentation - Overview Coordinator: Dr. Lynann Clapham, Physics Department Program Assistant: Aphra Rogers, Physics Department Webpage address http://appsci.queensu.ca/courses/APSC100/module2/

  2. Scheduled labs for APSC100 Module 2 start NEXT WEEK. The schedule for weeks 2 and 3 is below. All classes in Stirling room 405 Note – if you decide to go into J section you stay in the same APSC100 section

  3. 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

  4. 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)

  5. APSC 100 Introduction to Experimentation WHERE – you will be: • Stirling Hall (Physics) rooms 405/406 • assistance on error propagation assignment in week 1 • tutorial labs in weeks 2 and 3 • all physics experiments Labs 1,2,3 • Chernoff Hall (Chemistry) room 206 • experiments 4, 5 • Dupuis (Chem Eng) room 236/237 • experiment 6 Manual page #1

  6. APSC 100 Introduction to Experimentation 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 work is required! Manual page #1

  7. 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 weekat time listed on the bottom of the worksheet. Come prepared!!!

  8. APSC 100 Introduction to Experimentation Structure: • Weeks 2 and 3: Tutorial Labs • Weeks 4-9: 3 Physics and 3 Chemistry Experiments • Weeks 10-12: Project Experiments Manual pages 7-16

  9. APSC 100 Introduction to Experimentation 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 spring • constant for a spring. A step-by-step design guide • (manual Appendix 7) is provided to walk you through the experimental design procedure. Manual pages 7-16

  10. APSC 100 Introduction to Experimentation Structure: • Weeks 2 and 3: Tutorial Labs • Weeks 4-9: 3 Physics and 3 Chemistry Experiments • Weeks 10-12: Project Experiments Manual pages 20-62

  11. APSC 100 Introduction to Experimentation Physics and Chemistry Labs: Weeks 4-9 • 3 Physics Labs: • -Cantilever Beam formal lab report • -Filters (high pass and low pass) in-lab analysis* • -Electrical Resistive Behaviour of 3 Devices formal lab report • 3 Chemistry Labs • -Titration in-lab analysis* • -Spectrophotometric Analysis in-lab analysis* • -Calorimetry (Chem Eng)formal lab report * No formal reports for these - answer sheet will be handed in at the end of the lab Manual pages 19-68

  12. APSC 100 Introduction to Experimentation Structure: • Weeks 2 and 3: Tutorial Labs • Weeks 4-9: 3 Physics and 3 Chemistry Experiments • Weeks 10-12: Project Experiments Manual pages 125-148

  13. APSC 100 Introduction to Experimentation Project Experiments: Weeks 10 - 12 • 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 ) Manual pages 125-148

  14. APSC 100 Introduction to Experimentation • 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

  15. 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. Manual pages 4-5

  16. APSC 100 Introduction to Experimentation • 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

  17. APSC 100 Introduction to Experimentation ASSESSMENT AND MARKING for formal reports 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 –

  18. APSC 100 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. Resources to help you: • 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 and APSC100 covered some basic principles of technical writing – refer back!. • The grading criteria (for A, B, etc) that the TA’s use is in the Module 2 portion of the manual on 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 Manual pages 4-5, 75-91

  19. APSC 100 Introduction to Experimentation • 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: formal lab reports are submitted electronically for marking, and automatically are added to the copychecker database. The copychecker is run at the end of the term, comparing your report to all others (including upper years) and looking for similarities.

  20. APSC 100 Introduction to Experimentation To avoid repeating APSC100: 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!!!

  21. APSC 100 Introduction to Experimentation What should I do before next week? • 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

  22. Scheduled labs for APSC100 Module 2 start NEXT WEEK. The schedule for weeks 2 and 3 is below. All classes in Stirling room 405
