THE MAGIC OF NATURE POEM WRITTEN BY SAFALYA PAL

THE MAGIC OF NATURE THE MAGIC OF NATURE OUR WONDER DOES GROW THE SECRETS OF NATURE ARE NOT FOR THE HUMANS TO KNOW THE MAGIC OF NATURE IS FOR ALL TO SEE IT IS ALL AROUND YOU AND ALL AROUND ME THE BEUTIFUL SCENIC VIEW EVERYTHING SEEMS AWESOME AND NEW LOOKING AT THE AWESOME SIGHT YOU FEEL SO TRANQUIL AND DELIGHT THINK HOW THE LUSH FORESTS ALWAYS REMAIN GREEN THINK WHY THE WATER DOESN’T ACCOMPLISH THINK HOW THE NORTHERN LIGHTS ESTABLISH THINK FROM WHERE DO WE GET NATURAL THINGS WE GET ALL THESE FROM THE NATURE AND THOSE ARE POSSIBLE FOR NATURE’S MAGIC! THE NATURAL BEAUTY OF NATURE HAS SO MUCH TO SAY, THE BEAUTIFUL CROSSROADS AND LONG WAY, THE NATURE HAS ITS CHARM, KEEP IT SAFE AND DO NOT HARM, THE NATURE WILL KEEP US UNSAFE, IF WE DON'T KEEP IT SAFE!                                               - SAFALYA PAL

Electricity and Circuits, NCERT NOTES, Class 6

Electricity and Circuits

Current

  • Current is the flow of particles in a particular direction. E.g air currents that cause winds or water currents.
  • When particles flow in an electric circuit to produce electricity, it is called an electric current.

Electric current

The flow of electric charges in a circuit is called an electric current. The direction is taken from the positive terminal to the negative terminal of the battery in an external circuit.

Electric Cell

  • A cell is a source of electric power, created inside by internal chemical reactions.
  • When the chemicals inside the cell are exhausted, the cell needs to be replaced by a new one.
  • Cells have two terminals: a positive and a negative terminal. In order for current to flow, the positive terminal must be connected to the negative terminal and this polarity must be maintained.
Electric cell

Wire

  • An electric wire is a conducting path in an electric circuit, through which current flows.
  • It is usually made out of a metal that is a good conductor of electricity.

Wire

Electric Bulb and its working

  • Consists of a thin wire that glows due to the passage of current. This is known as the filament.
  • An electric circuit provides a closed path for the current to flow. Terminals of the bulb are connected by wires to the electric cell.
  • Sometimes the bulb does not glow as the filament gets fused (breaks) due to overheating.
Electric bulb

Electric circuit

  • A closed-loop path which the current takes is known as an electric circuit.
  • When the path of the circuit is closed, current flows through it.
  • When there is a break in the path (switch is open) then, the circuit is open and not conducting so the current does not flow.
Electric circuit

Electric switches

  • Devices that are used to connect the circuit or break it.
  • When the switch is connected, we call it ON, and when it's not in contact (or open) with the circuit, the switch is OFF.​​​​​​
ON position
 
OFF position

Conductors and insulators

  • Any material that allows the electric current to pass through it is called as the conductor. Eg: metals like copper
  • Materials that do not allow the free flow of current through it are known as bad conductors or insulators E.g: Rubber, plastic

TOWN PLANNING IN INDUS VALLEY ➡

  ⚫TOWN PLANNING IN INDUS VALLEY ➡ It was all about how they planned their cities. The cities were divided into two parts. One part smaller and the other part bigger. The smaller part was raised above the ground about 12 meters height and it had massive walls surrounding it. The walls protected it from floods. It seems like a proper fort, Na? The archaeologists also thought so. That’s why they named it Citadel. Most of the important people like the kings, the royal families, the priests, they all lived here. The other part was bigger in size and it had all the residential buildings and the public facilities. It was the place for the common people and it was situated below the Citadel. So we call it the lower town and not just that the cities was guarded so well that they have watch towers made of stone to keep a watch on enemies. So that the cities was not only protected from flood but also from any attacks. The Harappan cities had an awesome system of water supply. There was no discri

ALL ABOUT PINHOLE CAMERA, NCERT NOTES, CLASS 6

  PINHOLE CAMERA The pinhole camera is based on the principle that light travels in a straight line. Construction of a Pinhole Camera- To construct a pinhole camera follow the steps described below - Take a small box like a shoebox. Paint the box entirely in black to light-proof it Appropriately determine the distance between the film of plastic or ground glass and light source and make a circular pinhole on the bottom of the box Make a shutter by cutting a piece of thick black chart paper. Use sturdy duct tape to hold the shutter in place Use a light adhesive to control the shutter flap and light entering the box Make a viewfinder out of cardboard. Pinhole Camera Image Characteristics- A real image is obtained as the image is obtained on the screen. The size of the image obtained is comparatively smaller than the actual object. The image is inverted on the x-axis as well as on the y-axis. The image can be used in the analysis of the rectilinear propagation of the light. Uses of a P

What is mucilage, how does it emerge?

  What is mucilage, how does it emerge ? Mucilage or "sea snot" is the result of the overgrowth of microscopic algae called "Phytoplankton", which constitutes the first step of biological production in the sea. The thick, mucus-like slimy layer contains a variety of microorganisms.  Mucilage formation, which is a secretion released into seawater in response to changes and anomalies in sea conditions, requires a stagnant sea as well as a high amount of nitrogen and phosphorus contents.  Mucilage, which is a part of a natural process under normal conditions, can expand excessively when the weather gets warmer in the spring months and it finds the right temperature and light.  However, as in the case of the Sea of Marmara, experts say the structure of the sea, as well as intense pollution and waste, and global climate change, are the main reasons beyond such intense mucilage formation.
