Introduction
This Web-based activity is specifically designed to
engage learners in a high school chemistry class (10th to 12th grade)
to learn about hydrangeas. This site may also be used as a resource
for home gardeners and hydrangea lovers.
As you move through the site, you will develop skills
in project management, scientific inquiry and experimental design for
growing hydrangea plants a certain color. Hydrangeas are of interest
because of their unique characteristic: the color of their flower is
dependent on soil condition. In the process of learning how to grow
hydrangeas a specific color, you will emerge yourself in learning about
acids, bases, pH, soil quality and botany. You will work collaboratively
in gathering background information and designing an experiment to investigate
a real-world problem.
You may or may not have been introduced to acids and
bases and their association with pH. Background chemistry lessons are
provided to make sure you are comfortable with important content information.
At the completion of this investigation, you will be
able to answer the following question:
How can soil properties change
the color of the flowers on a hydrangea plant?
