Home Learning 15-10-09

15 May

There have been some great album art coming in for home learning this week.  Special mentions go out to the great Lily Allen cover and a new take on the Peter and the Wolf album cover.

This weeks home learning is all about sound proofing.  Next week we will be solving a problem for Mrs Forster.  Mrs Forster has a very loud alarm clock and she can’t sleep as a result.  She needs some way of soundproofing it.  In order to offer her some advice I need to find out what is the best way of keeping down the sound.  Have a think about what might be the best way of reducing the sound of the bell!  Record your ideas however you would like for use in our session on Wednesday.  Good Luck.

    One way to make it quieter is to put two pieces of foam where the hammer hits and it will make a less noisy sound. Another way is to put a tea cosy over it. A third way is to put it in another room, now i know what your thinking ”hows she going to here it” well say if my mum was in the kitchen and i was in the living room i probably could still here her but not very well and i can here her better up close so if the clock was in another room she could still here it just it wuld be a bit quieter. that was my homework
    hope you like it MR.C

    I thought not being able to sleep was the whole point of alarm clocks?

      The problem is that it ticks too much and Mrs Forster can’t get to sleep in order that she can be woken by the bell!

    We understand sound is a form of energy.
    When we thought of Mrs Foster’s clock, we were worried that if we insulated it too much, she may not wake up at all in the morning, to come to school!

    We thought we could make a cover to put over the clock, but make sure it sits on a carpet surface. The carpet will insulate the sound well. For example, people have carpeted floors in flats so they don’t annoy the people downstairs.

    We would do an experiment using the LogIt. We would firstly, test the normal sound in the classroom, using the LogIt . Secondly, place Mrs Foster’s clock on a carpet surface, 30cm away from the LogIt.. Then introduce the different covers for the clocks, using various materials of the same width.
    The materials would be:-
    bubble wrap
    plastic
    cardboard from an egg box
    wood
    cling film
    foil
    fleece
    double glazing glass
    metal
    paper

    We think the best sound insulator would be plastic, but would Mrs Foster heard the alarm at all?
    Perhaps the best solution would be wood!
