Allotropes of Sulphure. Producing plastic sulphur.

There are a large number of allotropes of sulfur. In this respect, sulfur is second only to carbon. The most common form found in nature is yellow orthorhombic sulfur, which contains puckered rings of S8. Chemistry students may have seen “plastic sulfur”;plastic sulphure is a mixture of long chain polymeric sulfur forms, two of which have been identified as allotropes.

This video represents how to produce plastic sulphur in chemistry lab. Read More…

Common accidents that can occure in chemistry lab. Watch it and prevent you from such accidents.

Chemistry lab is the coolest place ever in school and there where the magics and miracles happens. So almost all of the student love chemistry lab.
As well as it is an interesting place, it is the dangerous place ever in school. Because chemistry experiments may cause lots of accidents such as explosions. This video will show you some common accidents which accidents which occur in the chemistry lab. Watch it and prevent your self from such accidents.

Is it Magic…? Nop..! Its Science (bernoullis principle). Unbelievable science experiments which is like magic. Watch it and learn some science + magic

Bernoulli’s principles is a awesome area in physics. Almost all of science student who study about the particular theory, they love the application (magic) of it.

The practicle applications of bernoullis theory is really MIRACLE and MAGIC for those who don’t know about the theory.

How to study A/L physics? vedio. By: S.R Jeyakumar BSc, PDGE, PDGIT

This is a video which will guide A/L tamil medium and as well as english medium students who speaks tamil and who studies in A/L science stream, this vedio will help you some in that “how to study physics?”.

We went to NOBLE ACADEMY to take this video. (you will be able to know about NOBLE ACADEMY in TUITION CLASSES, in our home page).

We would like to thank to lots of people who helped us to make this vedio.
Specially,

Mr. S.R Jeyakumar (BSc, PGDE,PGDIT)
Mr. U.Umarshanger (BSc, Dip.in Edu)
Dr. Suhail A Wahab, whom gave me advices to make the recording to be perfect.
Ismail A Azeez (Trainer/Motivational Speaker Trainer/ Motivational Speaker MBA (Rdng), BA (Sociology), DYDW (Commonwealth), DICS (NCC-UK), ACS,Trainer CGAP/ Business Edge), my uncle who motivates me to do all these.
Dr. Shafna, who gave me lots of advices that how to do the conversation and how to make the script to be perfect.
And my friends,
Nuski Ibn Hazeem
Arshard
Ramesh
Praneeth

This is a little effort taken by us and a small gift to our community.

🙂
Feel free to share it to your friends and known one.
Thanks.

Ripple tank

A ripple tank is a shallow glass tank of water used in schools and colleges to demonstrate the basic properties of waves. It is a specialized form of a wave tank. The ripple tank is usually illuminated from above, so that the light shines through the water. Some small ripple tanks fit onto the top of an overhead projector, i.e. they are illuminated from below. The ripples on the water show up as shadows on the screen underneath the tank. All the basic properties of waves, including reflection, refraction, interference and diffraction, can be demonstrated. Ripples may be generated by a piece of wood that is suspended above the tank on elastic bands so that it is just touching the surface. Screwed to wood is a motor that has an off centre weight attached to the axle. As the axle rotates the motor wobbles, shaking the wood and generating ripples.
