- Learn about sources of Light , the Sun and how it works.
- Learn about colour, light and everything else that matters about light.
- Be a space explorer as you learn about light and dark
- Light travels in a straight line
- Light can be reflected.
- Hard, smooth and shiny surfaces are good reflectors of light
2. Transparent, Translucent and Opaque (under construction) Have you ever wondered what is the difference? Take a look to find out more. 3. Shadows Take a look at these amazing videos on shadows.
Learn how to make such hand shadows.
4. Learn about shapes and sizes of shadows Light and shadow You will learn that:
- Shadows can be made bigger by either moving the light source closer to the object or the object closer to the light source.
- Tilting the light source can also cause shadows to be formed
- Different objects will cast different shapes of shadows.
5. Learn about the effects of the Sun and ...hmmm....Moon?
Light and dark You will learn that :- The sun is the source of light.
- The sun rises from the east and when it is low in the sky in the morning, shadows are long and they point to the west.
- The sun sets in the west and as it is low in the sky in the evenings, shadows are also long and they point to the east.
- When the sun is directly above our heads at noon,the shadows are short.
- The moon is NOT a source of light but it reflects the light from the sun. The reflected light is sufficient to cast shadows.

I have learnt that the sun is the main source of the light.
Our hands can make shadows that are so real. Great video!
I learnt that Energy enables thing to move
I have learnt that Heat keeps us warm
living need energy to move
I have learnt that light goes straight.
heat can make us warm and won"t be so cold
I have learnt that light enable us to see
I have learn alot from the websites and the videos.I learn that Transparent materials let light to pass through them in straight lines,so that we can see clearly through them.Glass in an example of a Transparent.I also know that Translucent materials let some light through,but they scatter the light in all directions,so that we cannot see clearly through them.Tissue paper is an example of a Translucent.Opaque materials do not let any light to pass through them.They block the light.Wood is an example of Opaque. I learn this on the websites!
Hi there Nurul!
Good job! I think you've managed to learn those concepts on your own. You are indeed being responsible for your own learning. Continue to have the passion for learning and discovering. How do you feel when you discovered all that on our own?
err...... The shadows r wonderful!=)
Today, 25th September 2007, Tuesday is a mooncake festival. Chinese peoples enjoy eating mooncakes on this speacial day. In mooncakes there is many types of flavours such as Kaya, Coffee And many more. There is also a speacial legendary story about a girl who ate mooncake and went up to the moon.
The hand shadow is very interesting way to learn more about shsdows.I think it is a good way to learn by ,putting interesting things about what we have leare in this blog.
I learn that when light is blok by an oject, it will cast a shadow!I also learn that clear glass, clear plastic..can be seen throught.But lace cloth can see throught a litter bit and it is called Translucent meterial.But green plastic and many more cannot see througthso it is called Opaque.
SCIENCE IS MY FAVOURITE AND IT ROX!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!I learnt alot from the science blog which is interesting and educational
i think heera should have written about science other than mooncaka festivals or others
Can we not be anonymous? I'm sure you have a wonderful name.
