Expect aswathi ,sivsni and faaida to draw analyse and explain further observaitons -like does the  angle change the nature of the shift ?
NAjia and trina will give reason for these changes viji ma'am

Conclusion: When lights travels through different mediums , there are either changes from its original place or it bends.
Good ! Ayesha you could drawans anlayse the rays ,Navya you should try drawing  and label the  refraction through a glass slab-Viji Ma'am]]> 2016-10-17 08:34:07 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131061666 https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131061708 When a coin or scale is immersed in water, the objects appears enlarged. It looks different from each possible views. But if it is seen from the top, the object appears in the same size. This is observed because of the refraction.
CAN TRY TO DRAW AND ANALYSE viji ma'am

-The light travels faster in air than in water.
-When observed from a particular angle the pencil is enlarged, while in other angle it is bend while viewing from above it remains normal. Therefore  the angle of observation is one of the factors depending on refraction.
Well differentiated with repec tto angles!-viji ma'am

Observation:
1. The pencil appears to bend when immersed in 
2. The pencil also seems to be enlarged.

Conclusion:
The light bends when it passes through different mediums. This is refraction.😊]]> 2016-10-17 08:36:06 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131061913 https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131062400 2016-10-17 08:39:38 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131062400 https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131062833 * when a pencil is immersed it appears to bend.
CONCLUSION: light bends through different medium.

Challenge yourselves,students!

Can explore more  how it it appearsand how it is seen from different angles and why parvathy and Surbhi can draw and anlayse  while Nasreen and Aysha should write about it. -Viji Ma'am]]> 2016-10-17 08:42:15 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131062833 https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131063012 When we immersed a pencil in the beaker filled with water we saw that the part from where the pencil was immersed it was large and when we viewed it from the top it was normal.we concluded that this was because of the optical density of the medium and the property of refraction
good inferences
did the pencil  seem shifted in positon also?

• Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.
• Angle of the incident ray – if the light is entering the substance at a greater angle, the amount of refraction will also be more noticeable. On the other hand, if the light is entering the new substance from straight on (at 90° to the surface), the light will still slow down, but it won’t change direction at all.

.When we place the mirror on a text , the letters are raised (seemed to be displaced from it's original position.)
.When we direct a ray of light (torch) towards the mirror the light seems to bend at the corners
But when we direct the light towards the surface regions of the mirror,light does not bend
Conclusion: For light to bend there should be an angle formed (at the corners of the mirror)
.OpticalDensity is also an important factor
This is called refraction of light.]]> 2016-10-18 16:47:36 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131551282 vijifrancis1230 https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131562052 girls please don't delet your previous answers and my comments,write further]]> 2016-10-18 17:11:31 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131562052 https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131698965 Our activity]]> 2016-10-19 06:55:50 UTC https://padlet.com/vijifrancis1230/2ot0p27ovok4/wish/131698965
