Table salt crystals, NaCl

crystal is the purest form of solid. Here is the NaCl (Table salt), crystals. There are various types of crystals that are found in nature, like your diamond, quartz, salt crystals etc. It’s a slow process, that aggregates the two or many more same molecules to stick together in the same orientation to develop into a crystal….

Starch grains of potato under foldscope -Class 7

Iodine test is used to check the presence of starch in food stuffs where it turns blue black in colour .After the iodine test a thin peel was observed under the foldscope. My students were surprised looking at the starch grains which was blue black in colour. It was an amazing experience to all of…

Copper sulphate crystals under foldscope

Today I got an opportunity to watch Copper Sulphate under microscope . Copper Sulphate is a sulphate salt of copper. It can be seen as a large, bright blue crystals . It contains 5 molecules of water (CuSO4. 5H2O). It is also known as blue vitriol, cupric sulphate and Roman vitriol.   It is the inorganic…

Potassium permanganate crystals under foldscope

    I was very fascinated to observe the crystals of potassium permanganate under foldscope. Potassium permanganate is an inorganic chemical compound and medication. As a medication it is used for cleaning wounds and dermatitis. It has the chemical formula KMnO4 and it is a strong oxidizing agent. It dissolves in water to give intensely pink…

A suggestion : To use dyes that rotate the plane of polarised light

It’s been quite a long while since I last posted here… A small play with polarizing filters and the fern rhizome slides provided in deluxe foldscope kits, I came up with these images :: I’d want to know which dyes were used in staining as these seem to rotate plane of polarised light. It’d be…

K2Cr2O7

NAME: Shilpashree. S COLLEGE: CMR PUCollege, ITPL, Bangalore It was very interesting to see Potassium dichromate, K2Cr2O7 under foldscope. It is a common inorganic chemical reagent,used as an oxidizing agent in various laboratory & industrial application. It is a crystalline ionic solid with a very bright, red-orange color.The main use is as a precursor to…

#indiafoldscopephaseI#Salt crystal under the foldscope

30 students along with two science teacher of Maharshibidya Mandir, Silpukhuri, Assam participated in a workshop on foldscope utility conducted by Cotton University and Regional Science Centre Guwahati. There we got a foldscope from PI Dr.  Anjana Singha Naorem,  Asstt prof of Dept of Zoology, Cotton University. These pictures were taken by our students during…

Xylitol

This 5-carbon sugar used as a sugar substitute. Though found naturally in a number of foods, and a product of our normal metabolism, industrially it may be produced from wood and wood products. Here are two images with plane polarized and polarized light.

Effective del cafe en los latidos de la larva del mosquito

0D0AE68B-F02B-42B8-AD2D-12ED5DA86AAA We did an experiment where we added coffee to a mosquito larvae. ALl of us thought that the heart beat will go up – just like when we drink coffee. Coffee has caffeine that is known to affect heart rate. We were all surprised that the heart rate goes down. So our hypothesis was…

Red rose petal cells

Generally petals are brightly coloured to attract the insects for pollination. Red rose petals appear red due to the presence of the pigment anthocyanin.

Potassium Metabisulphite

Name: Shilpashree. S College:CMR PUCollege ITPL,Bengaluru I along with my friends observered, potassium metabisuphite  under a foldscope. I would like to give some information on this nanoparticle. Potassium meta bisulfite, K2S2O5, is a white crystalline powder with a pungent sulfur odour. The main use for the chemical is as an antioxidant or chemical sterilant. It is…

Maple Syrup with Polarizing lenses

As winter approaches, the Maples’ leaves change colors. In a few months, as it begins to warm, the tree produces a sweet sap which is boiled down to Maple syrup, over 100litres of sap are boiled to make 1 litre of the sweet syrup. After sitting out for a few days, it dries. Here is…

Aspirin Crystals Under Polarized Light

I have always been interested in polarized light and wondered if the foldscope could be made to incorporate it. Knowing nothing about optics, I was pretty sure that the viewing situation would be too compressed for this to work…but I still wanted to try. I purchased two plastic, linear polarizing sheets from Edmonds Optics.  I…

Wool fibres under foldscope

Wool is a natural animal fibre obtained from sheep.It looks like scaly corkscrews under the foldscope.The wool fibres are stretchable, long lasting ,doesn’t wrinkle  and springs back into shape.

Fibre to fabric-class 8

Fabric is made up of two set of yarns arranged together. The process of arranging two sets of yarns together to make a fabric is called weaving.                                                         …

Salt crystals under foldscope

I was very excited to observ I was very excited to observe salt crystals under foldscope .Salt  crystals have wonderfully distinctive crystal forms. They might well be good subjects for introducing minerals, crystals and some of the more complex geometric solids. The salt crystals are clearly cubic, even though some of the grains seem to…

Jute fibres – class 8

Jute is obtained from stem of jute plant.The stems of harvested plants are immersed in water for few days.The stems rot and fibres are separated by hand.The fibres are first converted into yarns and it is made into carpets,ropes etc.

Synthetic fibres under foldscope – class 8

Synthetic fibres and the fibres made by human beings. They are chain of small units joined together. Each unit is a chemical substance .Many such small units combine to form a large single unit called a polymer.                                     …

A calcareous cocoon-like structure on Chrysanthemum leaf

  A calcareous cocoon-like structure was seen on my Chrysanthemum leaves. I plucked and tried to foldscope it using time-lapse. But the shell dissolved a few hours later and I could only observe the structure of the shell. Is it a shell of a nematode or an insect ? This post is open to read…
