The document discusses David Vernier and his company's datalogging systems for science education, including their LabQuest and LoggerPro products. It describes how the systems make data collection and analysis easy and affordable for students and teachers. A variety of experiments are highlighted that use the datalogging systems to explore physics, chemistry, and biology concepts through direct measurement and analysis of real-time data.

1.  Collect

2. David was a physics teacher, who:
• Wrote software for PASCO.
• Created “Graphical Analysis”.
• Wanted to make datalogging available & affordable for all.
• Makes probes for many datalogger companies.
• Uses teachers to develop & test products.
• Makes the most reliable and useful datalogging systems.

5.  Install probe – auto recognition!
 Press start (adjust settings if necessary)
 Stop (graph will auto scale)
 Analyse (on colour screen or on computer)
Totally portable …. Rechargeable battery …. Save files to the logger
Full graphical analysis …. Colour screen LoggerPro

6. Collect data on Labquest
Save data file into LabQuest
Connect to a computer.
Connection will be recognised
and data downloaded
Connect to computer and
automatically download file.
Or try the Wireless Dynamic System.

7. Enter your data manually or via a logger then….
Manual analysis
 Predict relationship from graph shape
 Change the power of a variable
 Convert to a linear graph y=mx + c
Software modeling
 Get LoggerPro to do it for you.
Eg Analyse / curve fit / define relationship
Error bars– YES! percentage, absolute, variable
LoggerPro

8. Experiment manuals
• Written by teachers for the US education system.
• Supplied with disk of files in Word format
(great for cutomising for our schools).
• Each experiment has a file in LoggerPro which
sets up data collection automatically

9. Experiments with dataloggers .
• Biology – “Cell Respiration video”
• Chemistry – “Acid-BaseTitration video”
• Physics – “Ball Toss video”
From Vernier support disk
All experiments in the manuals link to a file in LoggerPro
software to automatically set up the collection rate & graph(s).

10. • Prediction (drawing graph patterns)
• Graph matching (walk the graph)
• Comparisons
• Defining a relationship
• Voice printing (and FFT)
• Interactive demonstrations
• Video analysis
• Use as an oscillosope & frequency generator

11. • Why do voices sound different when singing the same note?
• How can I accurately measure the speed of sound?
• Would an adult or a baby suffer from hypothermia first?
• How effective is penguin behaviour in keeping each other warm?
• How quickly do streams cool in cold air temperatures?
• Does the temperature of a fridge vary throughout a day?
• What clothing fabrics best protect us from heat loss?
• What rides give us the greatest acceleration?
• What substances are the most radioactive?
• How can I show standing waves?
• How do transpiration rates differ between plants?

12. • Appeal to many students
• Remove the boredom of some measurements.
• Improve accuracy of measurements
• Improve analysis
• Enable some measurements to be made (that couldn’t
be done in any other way).
• Makes results real and immediate
• Tufts University research + interactive demonstrations

14. And now for some ….
Interesting
applications!

15. Spectrophotometer
SVIS-Plus - For spectral analysis
Gas discharge tube
Emission spectra

16. Magnetic Field
- Magnetic field through a slinky carrying a current
•Shape of field
•Variation of B with current
•Turns density
…. etc

17. Is Acceleration related to thrill level?
Check these out using an accelerometer!

18. Rotational Dynamics
- Rotational inertia of various shapes
Outcome: Get the angular velocity- time graphs directly!

19. Standing waves
using the LabQuest’s output to drive a speaker and string in oscillation.
Standing waves, modes of vibrations and wave speed

20. Light Sensor
-Inverse square Law
-Light and reflection and heat absorption

21. Sound waves
Standing waves and speed of sound experiments
Sound from a tuning fork
Also excellent for BEATS
Using FFT to analyse a sound into
its component frequencies

22. Radioactivity
• Detection (alpha, beta and gamma)
• Spectrum of emission levels
• Effectiveness of Shielding
• Decay curve
• Identification of radioactive materials
