Class 6 Science Chapter 12 Electricity and Circuits Worksheet Pdf

Electricity

  • Electric energy is a form of energy which can be obtained from other forms of energy. It can also be converted to other forms of energy.

Electric current

  • Electric current is the movement of charges per unit time. Substances are grouped into insulators, conductors and semiconductors based on their ability to pass (allow the passage) of electric current.
  1. Conductors are substances that allow the passage of electric current easily. They contain freely moving electrons.

Example- metal

  1. Insulators are substances that do not allow the passage of electric current charge through them easily. They contain no freely moving electrons. Examples- non-metals
  2. Semiconductors are substances that allow the flow of only small current (charge) through them. They contain few freely moving electrons. Example – silicon

Voltage

  • The difference of electric charges a cross the terminals of a battery is called voltage. Voltage is measured in a unit called volt (V).

Voltage = Eclectic current x Electric resistance

  • Symbolically V = (I) x (R) where I = current, V= voltage, R= resistance

Electric circuit

An electric circuit is a closed path along which the flow of electric current takes place.

It consists of four basic parts (components)

  1. Dry cell is part of electric circuit which is source of potential difference.
  2. Connecting wire conduct electric current.
  3. Electric bulb part of electric circuit which converts electric energy into heat and light.
  4. Switch is part of electric circuit which off or on the flow of electric current.

Resistors (lamps) in parallel and series connection

There are two electrical circuits. These circuits can be connected in two ways in an electric circuit. 

Grade 5 G.S. note - 1

S2 = switch (2), S1 = switch (1), A and B = bulbs

Magnet

  • A magnet is a device that attracts iron and products a magnetic field.

There are two types of magnet.

  1. Bar magnet An electromagnet
  • A magnet has two poles.
  1. North pole (N) South pole(S)
  • Properties of magnetic poles( The law of magnet )
  1. Opposite poles attract each other.
  2. Similar repel each other.

Glands and Hormones

Glands

  • A gland is a structure in our body which produces some kinds of useful substances.
  • There are two types of glands in the body; exocrine and endocrine glands.
  1. Exocrine glands are glands that contain tubes.

-They release their products into the ducts/tubes/.

E.g. -sweat glands, Salivary glands, Mammary glands, Pancreas etc.

  1. Endocrine glands are glands which do not have tubes.

- They release their products into the bloodstream.

- These glands are sometimes known as ductless glands.

E.g -Thyroid glandPituitary gland, PancreasGonads Adrenal gland

The endocrine glands have different size and locate in different parts of the body. They produce hormones which directly release to the blood stream. The hormones produced by the endocrine glands are carried to all parts of the body by blood. In this section we shall learn the three most important hormones among the several hormones produced in the human body. These hormones include.

  1. Growth Hormone
  2. Thyroxin Hormone
  • Adrenaline Hormone

 Growth Hormone

The pituitary gland locates in the center of the head produces a large number of hormones. One of these hormones is the growth hormone. This hormone controls the development and growth of bones and muscles of the body. Under production/deficiency/ of growth hormone results in dwarfism. While over production/excessive/ of growth hormone causes gigantism.

Thyroxin Hormone

The thyroid gland locates in the neck region, in front of trachea produces a hormone called thyroxin hormone. The hormone contains iodine which is important for normal growth and development. The thyroid gland can produce a swelling in the neck called Goiter due to deficiency of iodine. The thyroid gland cannot produce enough thyroxin if our diet is deficient in iodine mineral. The main function of thyroxin hormone is to control metabolic rate in the body.

 Adrenaline hormone

The adrenal glands located just on the top of each kidney produce a hormone called adrenaline hormone. The glands produce adrenaline and release into the blood stream to be carried to various parts of the body. Adrenaline hormone is produced when we angry, fear and excite to help our body in producing much energy. Thus, during emergency situations, the adrenaline hormone released from adrenal glands.

The over-all objective of adrenaline hormone is to give us much energy when we are under emergency situations.
