MICROENCAPSULATION

The reasons for microencapsulation are countless. In some cases, the core must be isolated from its surroundings, as in isolating vitamins from the deteriorating effects of oxygen, retarding evaporation of a volatile core, improving the handling properties of a sticky material, or isolating a reactive core from chemical attack. In other cases, the objective is not to isolate the core completely but to control the rate at which it leaves the microcapsule, as in the controlled release of drugs or pesticides.

         I discovered that children can learn much from using their senses to help them associate words with their experiences.

It is always a challenge for students to verbalize their thoughts and experiences. With the following activity {USING THE SENSES TO WRITE A DESCRIPTIVE ESSAY.}they will find it a breeze to write down what they are thinking or experiencing. Working in groups will also facilitate cooperative learning.   

Our brain processes information and makes sense of it. We make more connections as we take in more information.

We need to teach children subjects that they can connect to after the lessons. So can children connect to how candy tastes? If they hold their nose, can they "feel" that there are sugars dissolving in the jelly beans as they are chewed- like I can? Can they realistically tell you when they no longer smell scents while holding the right or left side of their nostrils? These are two experiments we tried today.

Here are two biology links for sensory systems:

I grew up in West Mount Airy, attending Oak Lane Day School and the Akiba Hebrew Academy. I attended Boston University and then Philadelphia Textile. I worked for 20 years in the Apparel Industry, then I went back to Cabrini College to get my Pennsylvania Certification and Masters in Education(1999).  I worked for six straight summers teaching nature at local camps, and I also taught Organic Gardening to neighborhood children in Bala Cynwyd, where I live. I am an avid organic gardener and recycling freak! This year I received Lower Merion Township’s first-ever Go For the Green award for a homeowner.

I am a rising senior chemistry major at Bryn Mawr.  My interests include biology, chemistry, philosophy, and specific aspects of animal behavior.  Any suggestions about how to incorporate these concepts into education would be welcome.  I am still in the setting up my post graduation plans.  Also accepting suggestions for my future. 

For a detailed account of when, where, why, and how my love affair with science education began see the following link.  /exchange/node/2577#comment-65988  The abbreviated version is that I want to grow up and be just like my 10th grade chemistry teacher.
