Aster pilosus, also known as White Heath or Frost Aster.

Results of quadrant study: We found Aster pilosus has aggregate dispersion. The population of Aster pilosus around Liberty North is estimated to be about 3,500 bloomed flowers per acre.

Our ecosystem: We surveyed the land around our school. We found the flowers in the meadow. They were at the top of the hill and further down into the valley. The ecosystem had some large tress and various smaller plants.

Our Microclimate: The Aster pilosus around LNHS grows in clay soil that tends to have a pH around 6.

Research: http://www.illinoiswildflowers.info/weeds/plants/f...

Hypothesis: If Aster pilosus is abundant then the soil is acidic.

Procedure: 1.Identify plant. 2. Calculate population and determine dispersion. 3.Collect supplies to test the pH of the soil. 3. Test ph of soil where plant grows. 4. Test pH of soil where plant does not grow. 5. Record results.

Results: After testing the soil around Aster pilosus and the soil where Aster pilosus does not grow, we concluded that soil Aster pilosus grows in is slightly more acidic than the soil Aster pilosus does not grow in.
