Hello everyone!
My name is Shubhra,
I am in 9th grade and I study in Sparkling Mindz Global School .
I am a part of the Lodha Genius Programme , where I can explore subjects that I enjoy through courses.
I am in a course called Exploring The Microcosm , in which I am learning to use a foldscope . Today I used the fold scope to help me see the skin and pulp of a potato .
Today there was a new challenge! we needed to get a sample of the potato pulp.
The peel was comparitively easy to see through the Foldscope, because it was thin anyway and due to that there was no problem we faced.
The design of the peel was very interesting. They were very boxy and there was vey little water content in it compare to the potato pulp.
In this sample, I was also able to see the brown colour!
This also played a role in how visible it was.

But the pulp was the challenge. Naturally the potato pulp is opaque , so cutting a thin peice of potato wouldn't let the light pass through and so I wouldn't be able to see the cells, So we needed to mash them up and then put them under a microscope. this also meant that the cells would break and relase starch grains. They were basically the starch particles found in the cell, and they looked like mini orbeez through the foldscope.
Each time I looked through a lens that magnifies more, the starch particles looked evrn better!
Personaly, my favourite image is the one in 140x.
This time I also experimented with natural light and artificial light, I was able to see and incrimental change!
I used the 140x lens in my experiment.
In the natural light, the colours were much more visible and clear and defined, but in the artifiacal light, they were more fuzzy and blurry, and it was harder for me to find a state where the starch was visible.

My experiment - comapring
These are one of the exciting foldscope experiments I did today.
I can't wait to tell you more about my second one.
Thanks!
