Newton Disc (4th Grade)

Hello children of 4th grade!

As we all know, Sir Isaac Newton, discovered that discovered that WHITE LIGHT is made up of these colours:

REDORANGEYELLOWGREENBLUEINDIGO and VIOLET.


Don't you believe that? Then, try to do this experiment at home:

3D Glasses (6th Grade)

Good evening!

Pupils of 6th Grade created our own 3D glasses as a Science project.

What we needed:

  • A 3D glasses template (downloaded from Internet)
  • A piece of card stock
  • Red and blue cellophane
  • Scissors
  • Glue stick

Remember that the blue cellophane goes on the right eye.

It was easy and we all enjoyed watching 3D books and films.







This type of 3D glasses can be used for watching specially designed images called Anaglyphs.
So, we decided to create our Anaglyph images:






And this was our last Science Project this year. Good job, kids!

Our Newton Discs (4th Grade)

Hello everyone!

We have to congratulate the following 4th Grade pupils because they have created a Newton Disc at home. They are Ainara, Aina, Hajar, Hiba and Imad.





There are different version of the same experiment:




A part from creating a beautiful effect, we can prove that the rotating disc (coloured in yellow, orange, red, green, blue, indigo and violet) appears as white.

How is a raibow formed? (4th Grade)

Hello class!

We continue with our study of light.

Let's watch this video in class. It explains how a rainbow is formed (although most of us can imagine after working on refraction...;).

It also suggests a beautiful experiment!

The colours of white light (4th Grade)

Hello boys and girls!



As we all well know, Sir Isaac Newton discovered that white light is made up of many colours.
But we wanted to discover it the same way he did: using a prism and natural light.
So, this is what we did last day in class, have a look! It's easy and very beatiful, you can try it at home!

Experiment: the colour of objects (4th Grade)

Hello everyone!

In our topic LIGHT, we are learning why the objects are the colour they are... Hum...strange question, isn't it? 
Look at the following diagrams:




Let's see the example of the ladybug: 
  1. White light (made up of many colours) hits the ladybug 
  2. The ladybug reflects only red light 
  3. We see the ladybug RED.

But:
  • Black objects absorb all the light.
  • White objects reflect all the light.

EXPERIMENT:

1. Inflate different coloured balloons (black and white are necessary).

2. Explode the balloons with the sunlight and a magnifying class.




3. See which balloon is the first to explode and which the last.

(Thank you Anna for the experiment!!!)

Refraction of light (4th Grade)

Experiments to understand refraction, by 4th Grade:

1. Put a pencil into a transparent glass full of water. Observe how it seems to be bent:

2. First, draw an arrow on a paper and stick in on the wall. Then, fill a glass with some water and put it right in front of the paper. Observe how the arrow changes direction!!!






So, what does REFRACTION consist of?

Light bends and changes direction when it passes from one transparent medium to another (water, glass,...).

Newton's Disk (4th Grade)

Hello children of 4th grade!

This week, in class, we have "met" Sir Isaac Newton, one of the most important scientists in history.

Why has he appeared in our lessons? Because our topic for these days is LIGHT, and he made a huge discovery! He discovered that WHITE LIGHT is made up of many colours:

RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO and PURPLE.


Don't you believe that? Then, try to do this experiment at home:
