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 8 Assignment

Lab assignment #8

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 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.
