Estimating Population Cover With Transects: Answer the questions for Activity ??? on the Questions sheets
0.5
Estimating Population Cover With Transects: At every ???-centimeter interval, determine what color square the transect line is touching
10
Estimating Population Cover With Transects: Calculate the class average percent cover using the data for all ??? groups.
0.5
Estimating Population Cover With Transects: Draw a small dot every ??? centimeter along each transect.
0.0
Estimating Population Cover With Transects: Find the ???-cm starting point of the first transect drawn, and note color of the square the transect line is touching.
1
Estimating Population Cover With Transects: Record the color of the square in the "Transect Group Data" table on your data sheet (Transect ???, 0.0 cm)
10
Estimating Population Cover With Transects: Using the ruler and marker, make five ???-cm lines, or transects, on the Population Sheet.
2
Estimating Population Density Using Quadrats: Answer the questions for Activity ??? on the Questions sheets.
5
Estimating Population Density Using Quadrats: Calculate the average density of red squares and green squares per 6.25 cm^2 by dividing the total number of individuals of each color (from all quadrats) by the total number of quadrats, which is ???.
6.25
Estimating Population Density Using Quadrats: Calculate the density per square centimeter by dividing the average density of red squares and green squares by the area of one quadrat, which in this case is ??? cm^2.
3.0
Estimating Population Density Using Quadrats: Continue another ??? cm along the stem, and then cut the stem with scissors.
1000
Estimating Population Density Using Quadrats: For example, if each 1 m^2 quadrat contains an average of 10 individuals of one species, then an area that is 1 km^2 or ??? m^2, should contain approximately 10,000 individuals.
3.0
Estimating Population Density Using Quadrats: From the end of one of the stems, measure ??? cm, and then bend the stem at a right angle.
6.25
Estimating Population Density Using Quadrats: Make a ???-cm^2 quadrat using the chenille stem.
0.5
Estimating Population Density Using Quadrats: Overlap the bent stems to create a square with ends that overlap one another by ??? cm.
0.5
Estimating Population Density Using Quadrats: Quadrats in the field usually measure ??? m^2 or 1 m^2, although they may be any size.
2
Estimating Population Density Using Quadrats: Record the number of red squares and the number of green squares in the table for Activity ??? on the data sheet.

Estimating Population Density Using Quadrats: Record this information in the data table for Activity ???.
2
Estimating Population Density Using Quadrats: Record this information on the data sheet in the table for Activity ???.
2.5
Estimating Population Density Using Quadrats: The square should measure ??? cm x ??? cm.
