Scientific Investigation
Procedures on Site
-
Survey area for a flat surface.
-
Areas should be close to eachother, and should have the same landscape and conditions.
-
Set up 3 plots of 3'x3' (use string and flags to mark areas)
-
Find 3 logs with moss. Logs should be very moist and around 3 ft long.
-
Find 3 logs without moss. Logs should be moist and about 3 ft long. If you cannot find any logs without moss take moss off.
-
Find 3 strips of moss off of a log or rock. The strips of moss should be 3 ft long.
-
Cut 12 slips of paper and write moss on 3 slips, moss log on 3 slips, log on 3 slips, and bare on 3 slips.
-
Combine all slips into a container.
-
Walk to plot 1 and pull 4 strips. document the plot area and order in which you pulled the 4 strips.
-
Repeat step 9 for plots 2 and 3.
-
Take note of the conditions of day, plants near each plot, canopies, and other significant conditions for each plot.
-
Before applying seeds to appropriate hosts in plots, clear area of plants
-
Go to plot 1 and lay hosts in the order in which it was documented and pulled.
-
Any plots with bare ground needs to be watered before seed application.
-
For any plots that have logs, the logs need to be stripped to expose wood.
-
For any plots that have two of the same hosts next to eachother (log/log, moss/moss, or bare, bare) use a string to seperate them.
-
Logs and moss logs do not need any special treatments before seed application.
-
Apply seeds to hosts.
-
After application of seeds, water the hosts.
-
Repeat steps 12-19 for plots 2 and 3
