https://padlet.com/deannalabastide/zuapv3luasra Please write a comment telling me 3 key things you've learnt in our Science topic - Light and Dark. en-us 2016-11-12 18:39:00 UTC 2023-03-05 20:51:28 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Brightnessdown.png deannalabastide https://padlet.com/deannalabastide/zuapv3luasra/wish/137148229 I look forward to reading about your Science knowledge! ]]> 2016-11-12 18:42:11 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137148229 https://padlet.com/deannalabastide/zuapv3luasra/wish/137186590 I have learnt that 
1. When an opaque object blocks a light source a shadow is formed.

2. There are 3 types of different materials 
a. transparent [all light passes through].
b. translucent [some light passes through].
c. opaque [no light passes through].

3. There are different types of light sources ; 
a. natural light source like sun.
b. man made light source like candles, torch.

2. Light can only travel in a straight line. It cannot bend around objects. Thats why shadows are formed, when an object blocks light or reflects it.

3. There can be many types of light sources such as the sun, a lamp, a torch, or a candle. By the way the moon is not a light source because it only reflects light from the sun. Some sources are man-made and some are natural.]]> 2016-11-13 12:52:14 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137186740 https://padlet.com/deannalabastide/zuapv3luasra/wish/137187257 some light sources are man made and some are normal light sorces
I have learnt that when an opaque object is blocking a light source a shadow is formed. 
I have also learnt that if one light source can make one shadow then 3 or4 light sources can make 3 or 4 light shadows.
Another thing that I have learnt is that during morning time your shadow is big and as afternoon comes your shadow gets smaller. As night comes your shadow gets bigger again.
i also know that if your light source Is in east then you shadow will be formed in west and if your light source is in west then your shadow will be formed at east.

2. The materials that reflects light best are shiny, bright and smooth.
3. To create a shadow you need a light source and an opaque object to block the light.]]> 2016-11-13 13:12:29 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137187891 https://padlet.com/deannalabastide/zuapv3luasra/wish/137188612 In science, I learnt that when an opaque object blocks a light source it creates shadow. I know that opaque means you cannot see through it like a fridge. Another fact is that when a light source gets closer to the opaque object the shadow gets bigger and when the light source gets further away from the opaque object the shadow gets smaller. A light source travels straight until  it hits a reflective object then changes direction.]]> 2016-11-13 13:26:12 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137188612 https://padlet.com/deannalabastide/zuapv3luasra/wish/137189817 1.In science I learned what translucent means,it means some light passes through.
2. I have also learned that your shadow moves and the size gets smaller and bigger during the day.
3.Another thing that I have learned is that when the light source gets closer to the object the object becomes smaller and when the light source is further away from the object it becomes bigger.]]> 2016-11-13 13:49:33 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137189817 https://padlet.com/deannalabastide/zuapv3luasra/wish/137193557 More than one light source can make more than one shadow.
Shadows changes size during the day. For example in the early morning the shadow is long, at noon the shadow is short and later in the afternoon it gets longer again.Anything can make shadows also animals makes shadows.Do you need light sources to make shadows?]]> 2016-11-13 14:53:47 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137193557 https://padlet.com/deannalabastide/zuapv3luasra/wish/137198185 The sun is the biggest light source living on EARTH. more than one/1 light source can make more than 1 shadow .translucent means some light will pass throgh . opaqe means no light will pass throgh . transparrent means all light passes throgh.]]> 2016-11-13 15:57:16 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137198185 https://padlet.com/deannalabastide/zuapv3luasra/wish/137330855 1.

1.A shadow is formed when an opaque object blocks a light source because an opaque object does not let any light through.
2.I have also learnt that a translucent object lets some light through and a transparent object lets light through.
3.When the light source is further away from the object the shadow is going to be small. When the light source is closer to the opaque object the shadow is bigger.]]> 2016-11-14 15:15:46 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137397639 https://padlet.com/deannalabastide/zuapv3luasra/wish/137414251
In science I have learnt 
1. that a shadow is formed when a opaque object blocks the light source, because light cannot pass through an opaque object. Translucent means light can pass through the object
2.The bright, boiling sun shines on the moon and that is why the moon reflects.
3.I have also learnt that one object makes one shadow. Shadows change size during the day, in the morning the shadow is long, afternoon its shorter.

1. Shadows get taller whens it lower in the sky, but when the sun is higher in the sky the shadow is smaller!
2. Translucent means it will let some light through.
3. Shadows are formed when a object is blocking a light source!]]> 2016-11-15 15:12:34 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/137753351 https://padlet.com/deannalabastide/zuapv3luasra/wish/137769704
In science I have learnt that when an opaque object blocks out the light source it creates a shadow. I have also learnt that translucent objects are those through which only a little light can pass through so we cannot see through clearly. Transparent objects are those through which  light pass through  and we can see through them clearly. 
The size of the shadow is dependent on the position of the sun.
In the early morning when the sun is not above our heads our shadows are long , by mid day when the sun is directly above our heads the shadows will become much shorter. 
In the evening,  the shadow becomes longer again.  The sun is the biggest natural light source on planet Earth. When the sun is in the East the shadow forms in the west and when the sun is in the west the shadow forms in the east .

In science I have learnt that when an opaque object blocks a light source a shadow is formed.

I have also learnt that when a light source is further away the shadow becomes smaller and when a light source is closer to the object the shadow becomes bigger.

Another fact is that a translucent object lets some light through but an opaque object lets NO light through and a transparent object lets ALL the light though.

1) The size of a shadow depends on the distance between the light source and the object.  The closer  the light source, the bigger would be the shadow.  
2) Every object in the world is reflective. However some objects are more reflective than others. 
3) Rough surfaces reflect less light than smooth surfaces because light rays get scattered and some light is absorbed.]]> 2016-11-17 12:05:18 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/138362713 https://padlet.com/deannalabastide/zuapv3luasra/wish/138609633
An opaque object doesn't allow light to pass through but a translucent object allows light to pass through.

When sun shines on an opaque object, it will make a shadow.

Shadow is the dark  area around an object. In the morning time, the shadow is long then  it gets shorter in the afternoon when the sun is directly above the object then in the evening the shadow becomes longer again .

When the sun rays hits the moon, the moon surface reflects the light from the sun and the moon shines]]> 2016-11-18 04:16:15 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/138609633 https://padlet.com/deannalabastide/zuapv3luasra/wish/138856204 1. When you put your hand in front of the light source a shadow will form beside you.
2.When you move  the object closer to the light source it will  get bigger.
3. when you have something that is transparent light goes through. ]]> 2016-11-19 04:40:30 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/138856204 https://padlet.com/deannalabastide/zuapv3luasra/wish/138858805 1. I learnt that all light comes from the sun and that is how we get our light.
2. The moon is a very big mirror that reflects 20 per cent of the light to Earth.
3. If something is opaque, like a piece of wood, no light can go through it because it is not translucent or transparent.

There is a natural light source (the sun) and man made light sources (e.g. a light bulb which are electricity based, a torch which is battery based and, candle).
2. A shadow is created when a light source hits opaque (non seethrough) objects.

A shadow is bigger when an object is closer to the light source.]]> 2016-11-19 06:48:35 UTC https://padlet.com/deannalabastide/zuapv3luasra/wish/138859005 https://padlet.com/deannalabastide/zuapv3luasra/wish/138865008 1. I have learnt that when a light source is blocked by an opaque object no light can pass through . 2.All our light comes from the sun. 3. the moon is a very big mirror that reflects nearly all of the light
