Issac Newton, the light spectrum and why the sky is blue!

Posted in Uncategorized on February 11, 2013 by Mr Davy

Have you ever wondered why the sky is blue or why rainbows appear or are created when light passes through certain transparent or opaque materials?

The very best scientists look at the world around them and ask questions. Why does this happen? How does it happen?

Issac Newton created an experiment in a room by simply drawing the curtains and allowing light to pass through a small slit and through a prism (a 3D triangle made of glass).

Today Year 4 learnt that all of the colours of the rainbow make up white light (light from the sun and light bulbs). They also observed the phenomonem nof light passing through a liquid with milk molecules within. It helped us understand why the sky is blue and sometimes reddy orange during a sunset.

Star Constellations

Posted in Uncategorized on February 9, 2013 by Mr Davy

I love days like these. Fantastic learning by all and a selection of topics covered in one day, with one aim in mind, to decorate our playground with amazing constellations! The learning today covered, Maths, History, ICT, Science and Art!

First, we learnt about the history of star constellations and the relationship humans have had with stars, in recent history and ancient civilisations.

Then, we studied actual constellations and measured the lengths of the lines and the angles using protractors. After that, we identified the names of the constellations using planetarium software and learnt about the names they have been given. Finally, we took our converted measurements out to the playground. With metre sticks, protractors and huge chalks, we drew out these wonderful patterns.

Enjoy the pictures!

Earth from Space – Taken from the International Space Station (ISS)

Posted in Uncategorized on February 4, 2013 by Mr Davy

Excellent work today Year 4! Great work on your Fraction presentations.

Here is that video we watched today. It is footage from the ISS (International Space Station).

See if you can see Lightning storms and the Aurora Borealis (Northern Lights). Also, see if you can identify any countries and cities. Enjoy!

Phases of the Moon

Posted in Uncategorized on February 1, 2013 by Mr Davy

Today the class have been investigating why the Moon appears to change shape. We have been learning a song to o remind us how long it takes for the Moon to orbit the Moon.

Here are some photos of our investigation and links to great websites to learn more and play a Moon phase game:

Go to the ‘Space Centre’ and click the ‘It’s just a phase’ game.

Very rarely, when the angles of the Moon’s and Earth’s orbit is just right, the Moon travels across the face the of the Sun, making a ‘Total Solar Eclipse’. Here is our good friend Brian Cox, standing on the banks of the Ganges river in India, experiencing this awesome cosmic event!
