[Nfb-science] science experiments

[Shanthala Somayaji]

Dear all, 

I am a teacher of children with visual impairment working in an organization
called EnAble India, from Bangalore, India. In a new project, we are working
towards promoting math and science education for the blind and visually
impaired in India. As part of this project, we are looking at all the
experiments done at primary and middle school level and making them
accessible wherever necessary. We suggest adaptations, if required; provide
tactile materials/models to replace pictures/diagrams; suggest process
change if required; etc. 

I needed some guidance on how to conduct the following experiments:
1. Root absorbs water
2. Stem conducts water

This is usually done by keeping a balsam plant in a beaker containing
colored water. After sometime, it is observed that the plant (the stem and
the leaves) change color. Is there any way to show this experiment to
children who are totally blind?

If this is not the right forum to discuss science at a basic level, please
suggest pointers if you have any.

Thanks,
Shanthala
