General Tips for APBI200 Labs
- Always bring lab manual to the lab
- Read info about the upcoming lab before coming to the lab.
- All lab assignments are to be submitted as hard copies (in drop in boxes outside of the MCML102 lab).
- Lab assignments are due by 5pm a week after your lab (e.g., if you have a lab on Tuesday, your assignments is due following Tuesday by 5 pm)

Lab 1 Assignment
Lab 1 is a field trip - cancelled in 2019. You should however read the section in your lab manual for this lab as it provides information on soil formation factors.
No lab assignment to hand in this week.
Lab 2 Assignment
Reminder for the lab assignment:
All lab assignments are to be submitted as hard copies (in drop in boxes outside of the MCML102 lab).
Lab assignments are due by 5pm a week after your lab (e.g., if you have a lab on Tuesday, your assignments is due the following Tuesday by 5 pm)
Pls attach the following to your lab #2 assignment:
•Your hydrometer data sheet with sample calculations written out for at least one line in the data collection table (ie one time of measurement).
•The particle-size distribution curve. Don’t forget to include a title and axes labels. Indicate the % sand, silt and clay and the soil textural class.
•The table regarding the soil texture of two “mystery” samples (determined by hand-texturing). Include a brief justification of your answer.
•Calculation for sample used for demonstration of bulk density determination by core method.
Semi log paper (needed to draw the particle-size distribution curve) can be found in the attached pdf file. Bonus mark if you plot the data in Excel (but pls remember to use semi-log scale). Semi-log graph paper
Lab 3 Assignment
Lab assignment #3
Pls read the manual. Introduction for each lab includes all the information needed to answer lab assignment questions.
Required attachments for lab assignment:
•Your data collection sheet with calculations written out for both samples parameters (lines a through k), and for the first 2 tension values. Be sure to include units when you enter your data and to keep track of units when making your calculations.
•The water retention curves for medium and fine sand samples indicating air entry value (AEV) and air intrusion value (AIV). Use your data that you collected in the lab and also data provided in the appendix A (on p.91) of the lab manual.
Lab 4 Assignment
Useful collection of videos showing different types of parent material in their typical landscape settings can be found at http://landscape.soilweb.ca/
Another useful website where you can observe various parent materials is UBC Soil Monolith collection http://monoliths.soilweb.ca/

Please note that some tips re. unit conversion can be found in the attached [file http://lfs-sw.sites.olt.ubc.ca/files/2017/02/Lab_4-unit-conversion-tips.pdf]
The data set for soil organic matter calculation is available at SOM google spreadsheet
The data for soil water content calculation is available at Soil-water google spreadsheet
Lab 6 Assignment
Note: No Quest-to-go in 2019 (further information will be provided in-lab) - Meet in the regular location McMl 102A
- Pls note that it is important to view videos posted at the "Forest Floor" website (http://forestfloor.soilweb.ca/), which provides all necessary information for our lab 6.
- Here is file with slides for this lab http://lfs-sw.sites.olt.ubc.ca/files/2015/03/FF_LAB6_Mar1615.pdf
Lab 7 Assignment
Bonus mark - vote on the colour to paint Sandra's office Vote here
To learn key characteristics of 10 soil orders in the Canadian soil classification system, it might be helpful to view video clips posted at the website entitled Canadian Soil Orders (http://soilweb.landfood.ubc.ca/classification/ )
Lab 8 Assignment
For this lab, we will meet at the UBC Farm, located at 3461 Ross Drive. To get to the UBC Farm please check the directions provided at the Farm’s website at http://ubcfarm.ubc.ca/about/directions-hours-and-contact-information/ We will meet at the Farm Centre and to reach it, please go through the Farm gate, turn right, and follow the gravel road until you reach a red roofed building (the Farm Centre) located beside a small glass greenhouse. Activities planned for this lab will take you about you 1 h to complete, which leaves enough time to arrive to and from UBC Farm within allotted 2-h time slot.
