Mother's Day

For Mother's Day we made fingerprint pendants using polymer clay that we dried in the oven.

Science - Light Spectrum

Today we used prisms to  see the colours of the light spectrum.

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.

When white light shines through a prism, the white light is broken apart into the colors of the visible light spectrum. Water vapor in the atmosphere can also break apart wavelengths creating a rainbow.

Each color in a rainbow corresponds to a different wavelength of electromagnetic spectrum.

Baking Soda & Vinegar Volcano

Materials:

Baking Soda

Vinegar

A container to hold everything and avoid a big mess!

Paper towels or a cloth

Procedure:

Place some of the baking soda into your container.

Pour in some of the vinegar

Watch as the reaction takes place!

Result:

The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.

Dragon Eyes

                                                                                                                                                                     For this week's art lesson we drew dragon eyes using a pencil and charcoal. First we drew a box with a circle inside. Then we drew a diamond shape in the circle as the eye. After that we were given a piece of charcoal to lightly go over our work then we smuged it for design. We had to erase a circle then some of the bottom so we could draw the veins of the eyes. For the last part we did scale designs on the outside.

Dawn Orbiting Ceres 

Tomorrow, Friday 6th of March, a spacecraft called Dawn will enter orbit around a dwarf planet called Ceres. Ceres was discovered by a man called Guiseppe Piazzi on the 1st of January 1801. It takes seven years to go to Ceres. The diameter of Ceres is 950 km. Its surface temperature is -105 degrees celcius. Its Orbit period is 4.6 years. There are mysterious white patches on Ceres. They are believed to be patches of ice, meaning there may be life on this Dwarf planet.
