Quadrat+Stream+Study

=Quadrat Stream Study= Adapted from How 2 Teach Science We are going to investigate the populations of biotic factors outside our school. In this activity, we will use Quadrats to collect data samples to estimate the populations of various species living in our area. Working in groups of 4, we will select 4 random sample areas to collect population data and graph our results for comparison. Each student will be graded individually and as a group according to the rubric provided.

HW Question: What is a Quadrat Study?

Answer:

=Agenda:=

Build Quadrat (3 min)
Tape 4 rulers (of equal size) into a Square. Be sure all sides are equal length. Make sure the measurement lines face inside.

Hypothesis: What do you think you will find in your Quadrat? (2 min)
Record your Hypothesis at the top of the page on your clipboard. Put a Plastic sheet protecter over it (its drizzling).

Investigation (20 min)

 * Step 1** - Each group member will take a turn tossing (not throwing) the Quadrat to a random location. 4 students per group = 4 sample locations.

Location - Soil - Vegetation - Sunlight -
 * Step 2** - Record a description of the area in which you are sampling. Include the following:


 * Step 3** - Count and record ALL the organisms living in your Quadrat. List the different organisms, and tally the numbers.


 * Step 4** - Repeat steps 1 -3 (at a new location)
