Ideas for Sampling Templates
A sampling template is simply a device that helps you to determine
the size of area that you will sample. Here are a few ideas:
String and Nails:
What You Will Need
- four large nails
- 2 pieces of string 30 cm long
- 2 pieces of string 55 cm long
- metre stick
What To Do
- Tie one end of the 30 cm piece of string to one nail.
- Tie the other end of the 30 cm piece of string to a second nail.
Use the metre stick to make sure the string is now 25 cm long
- adjust if necessary.
- Repeat with the other 30 cm piece of string.
- Secure the 55 cm pieces of string to the nails and adjust their
length to 50 cm.
- Your sampling template should be a rectangle with the dimensions
25 cm by 50 cm.
Cardboard Frame:
Safety: An adult should build this template.
What You Will Need
- large piece of heavy cardboard approximately 35 cm by 55 cm
(a used lawn sign used in political/election campaigns works very
well)
- sharp knife or scissors
- pencil
- metre stick
What To Do
- Use the metre stick to lay out a rectangle 25 cm by 50 cm on
the cardboard.
- Cut the inside of the cardboard out leaving a frame. The inside
dimensions of the sampling template should be 25 cm by 50 cm.
Please note: This template can also be constructed with pieces
of scrap lumber and a couple of screws.
