GROUP 4 / CLASS VI SCIENCE –

CLASS VI SUBJECT Science NAME OF THE ACTIVITY: STUDY OF FABRIC/FIBRE

ACTIVITY PROCESS OBSERVATION INFERENCESCollect a 20 cm x 20 cm piece of thick cloth from a cloth shop.Observe closely the pattern of interwoven fibres in the cloth

Pull out one long yarn from one cut end and unwind it

Thick threads of yarn are seen inter woven

Yarn gives still fine threads

Fabric means clothFabric is made of yarn

Yarn is made of fibres.

CLASS SUBJECT NAME OF THE ACTIVITY: Study of NATURAL FIBRES

ACTIVITY PROCESS OBSERVATION INFERENCESYou are given four types of fabrics. Try to classify together with your friends based on their sources which are having stapled figures to help you

Cotton is rough and obtained from cotton plantJute is very thick and rough obtained from jute plant

Wool is soft and obtained from sheepSilk is soft to touch and obtained from silk moth

All these are natural fibres.Cotton and Jute are plant fibres.Silk and Wool are animal fibres.

CLASS VISUBJECT SCIENCE NAME OF THE ACTIVITY: STUDY OF SPINNING/ TOOLS

ACTIVITY PROCESS OBSERVATION INFERENCESHold some cotton wool in one hand.Pinch some cotton between the thumb and forefinger of the other hand. Now, gently start pulling out the cotton, whilecontinuously twisting thefibres

Folloowing pictures are the tools for spinning. Identify them

What are spinning mills?

We are able to make a yarn

The shown tools are Charkha and Takli

The process of making yarnfromfibres is called spinning.Fibres from a mass of cotton wool are drawn out and twisted. Spinning brings the fibres together to forma yarn.

Spinning is done by using are Charkha and Takli.

NAME OF THE ACTIVITY: CONCEPT OF WEAVING USING PAPER STRIPS

ACTIVITY PROCESS OBSERVATION INFERENCESTake two sheets of paper of different colours. Cut square pieces of length andwidth equal to 30 cm from each sheet.Now, fold both the sheets into half. On one sheet draw lines as shown in the Fig 3.12 (a) and on the other as shownin Fig.3.12 (b). Cut both the sheets along the dotted lines and then unfold.Weave the strips one by one through thecuts in the sheet of paper as shown inFig.3.12 (c)..

GROUP IV CLASS VI SUB : SCIENCE

CLASS; TEACHER ACTIVITY NAME OF THE ACTIVITY; SEPARATION OF SUBSTANCES USING SEDIMENTATION, DECANTATION AND FILTRATION

ACTIVITY PROCESS OBSERVATION INFERENCE-Take soil sample and mix it in a beaker full of water-allow the mixture to settle for some time-pour the uppermost liquid into another beaker-take a filter paper and make it into a cone and pour the decanted water into the funnel with the help of glass rod and filter paper-observe the filtered liquid

-soil, sand and small pebbles settle to the bottom -dry leaves and other lighter particles floats on the surface-decantated liquid is muddy-after filteration we obtain clear liquid in the beaker, and the filter paper turns muddy.

Three methods of separation-sedimentation-decantation-filteration

STUDENT ACTIVITY AT SCHOOL NAME OF THE ACTIVITY: SIEVING

ACTIVITY PROCESS OBSERVATION INFERENCE-Take a mixture of different sizes of components-mix them properly for example, wheat flour and sugar_take a sieve and start sieving the mixture Observe the separated components

-

-the sieve will have sugar particles on the surface- the plate under the sieve will have wheat flour

We can use sieving to separate two different size particles.

STUDENT ACTIVITY AT HOME NAME OF THE ACTIVITY:HANDPICKING

ACTIVITY PROCESS OBSERVATION INFERENCE-Take a mixture of rice , small We can separate three large size Method of separation is

stones,wheat-separate them into three component by hand

particles using our hand handpicking

CLASS: VI NAME OF THE LESSON : CHANGES AROUND US

STUDENT ACTIVITY IN THE CLASS NAME OF THE ACTIVITY:CAN ALL CHANGES ALWAYS BE REVERSED

ACTIVITY PROCESS OBSERVATION INFERENCE-Take a balloon and blow it-the shape and size of the balloon change-let the air escape the balloon

-the balloon gets inflated-the shape changes and size increases-the balloon shape and size changes to the original condition

Change can be reveresed

STUDENT ACTIVITY AT HOME NAME OF THEACTIVITY: SOME CHANGES CANNONT BE REVERSED

ACTIVITY PROCESS OBSERVATION INFERENCE-mix some wheat flour into a dough-roll out a ball of it and make a chapatti out of it-and bake it on a tawa

Wheat flour is cooked into roti Some changes cannot be reversed

TEACHER ACTIVITY IN THE CLASS NAME OF THE ACTIVITY:MELTING AND BURNING OF WAX

ACTIVITY PROCESS OBSERVATION INFERENCEMELTING OF WAX-Take some wax in a pan and heat it BURNING OF WAX-Take a small candle and measure its length with a scale-now fix it and light it -let it burn for some time-now blow out the candle and measure its length

Solid wax will convert into liquid

The length of the candle will decrease

-change is reversible

Change is not reversible

CLASS; VI NAME OF THE LESSON:GETTING TO KNOW PLANTS

TEACHER ACTIVITY NAME OF THE ACTIVITY: IDENTIFY THE HERBS,SHRUBS AND TREES

ACTIVITY PROCESS OBSERVATION INFERENCE-Students visit the school garden and observe different plants -they compare the plants based on their height-they differentiate based the stem and branches

-some plants are small and very close to the ground-some plants have the stem branching out near the base, and the stem is hard but not very thick- some plants are very tall, hard and thick brown stem, the stems have branches in the upper part

--Herb

-shrub

-trees

TEACHER ACTIVITY NAME OF THE ACTIVITY:FUNCTION OF THE STEM

ACTIVITY PROCESS OBSERVATION INFERENCE-Pour water in a glass, and fill one third of it-add two drop of red or blue ink to the water-cut the base of the stem of the herb(balsam)-put the plant in the glass -leave it for one day-cut the stem and observe it

-the stem of the plant and leaf veins and flower if any will change its colour to blue or red-red spots are seen inside the stem

-stem conducts water

STUDENT ACTIVITY AT HOME NAME OF THE ACTIVITY:TO STUDY THE LEAF VENATION

ACTIVITY PROCESS OBSERVATION INFERENCE-put a leaf under a white sheet of paper or a sheet in your notebook.-hold it in place , hold your pencil tip sideways and rub it on the portion of the paper having the leaf below-trace the impression and observe-repeat the activity for at least five leaves

-each leaf has a different venation and design-some leaves have parallel lines in the impression-some leaves have zigzag lines

-leaves are of two types parallel venation and Reticulate venation
