  1. 1. We made sure the test was fair by keeping the same person making the noise same person using the cups as headphones and same person measuring the distance.

    2. We kept the same person making noise and the same person listening with the cup filled with the material on your ears.

    3. We changed the material and the distance of meters.

    4. We presented our data with a bar chart, the bar chart was effective by making sure we didn’t forget if it was muffled,clear and not clear.

    5. Our results show that everything was clear.

    6. We could use different materials next time.

  2. 1. The investigation was a fair test because the same person was speaking and the same person was hearing what the other is saying.

    2. It was the same person speaking and the same person talking every time.

    3. You have to change the materials.

    4. We present it by a table.

  3. 1)We made sure the test was fair because we used the same person to hear, the same person to make the noise and the same cups.

    2) The controlled variable was we kept the same person hearing, measuring and the distance.

    3) The controlled varible was we changed the material.

    4) We presented our data in our key.

    5) Our results showed that the tissue paper was the best of the vibrations and the least best was cardboard.

    6) If we do this again I would change stuff to see what would happen and if the results would still be the same.

  4. 1. We made this a fair test by making the same people make sounds and blocking off their ears from the sound.
    2. We kept same cups.
    3. We didn’t keep the materials.

    Imran, Princess and Mandy.

  5. Yes it was ensured
    We keeped the same person so it was a fair test.
    The independent variable was we changed the meters from 1 to 2 to3

  6. We could make it a fair test by keeping the same person testing the investigation.
    The control variable the sound and the distance.
    The Independent variable is the distance
    We presented our data by distance some has to speak by far.
    That some you can hear but some you can’t hear.
    You can do differently the distance.

  7. The investigation was a fair test because the strings was the same length and the cup was filled up to the same height.
    The same person would test the same thing.
    We changed the materials.
    We presented our data in a table and this was effective because it was clear.
    My results was all the materials was clear for me.
    We could add more materials next time.

    Marvin,Andrei,Sarah and Chloe.

  8. 1)We put the volume at full so it can be a fair test
    2)the volume
    3)the material
    4)we put it in a table and it went well
    5)cotton wool was the best material to use for ear muffs
    6)we made sure that we had no background noise

  9. 1.Because had to get the volume up to hear the music from a mile.
    2.To hear the music so you can hear it far from the iPad.
    3.We changed the material for a better volume.
    4.In a table
    5. My results show cotton wool the less loud

  10. We used the same materials
    Same volume and same cups swoped the materials
    We showe it in table

    Cotton was better

    The background noise

  11. We made sure it fair test because we had the same music and we made sure it was the right length

    The music stay the same then material stay the same then we change it

    we change the material

    We present in a table next time we could do a bart chart

    My result show that I was crorrt because I predicted cotton wool and cotton wool was crorrt

    Back ground nouise can impact your investigation

  12. 1.We kept the IPad in the same place.
    2.We kept the music on the IPad the same volume.

    2.We kept the music of the I Pad the same volume and kept the I Pad in the same place.
    3.We kept on changing the metres to 1metre to 2metres to 3metres and we changed our materials.
    4.We used different materials to see whatever material is the best to ear muff your
    ears and it was effective.
    5.My Results showed me that I was incorrect.
    6.No nothing impacted it.

  14. 1. How did we ensure the investigation was a fair test.
    We ensured it was a fair test by making the cups the same size and we made sure that the same amount of material went inside the cup.

    2.what was the controlled variable.
    The controlled variable was the thing that we changed which was the material.

    3. What was our independent variable.
    Our independent variable was the volume.

    4. How did you represent your data? Was this effective,how else could you have done this.
    We represented our data using a chart it was effective but we could have used a tally chart or a bar chart.

    5. What did your results show?
    Our results showed that cotton wool was the best material and paper was the worst material.

    6.did anything Impact the reliability of your investigation.
    The background noise was going to effect it but we ensured there were no background noise.

  15. 1. We made sure it was a fair test because we had the same material and same music .
    2. We kept the music of the I pad and the same voice
    3 we chooses different materials
    4. We present in a table next time we could do a bar chart
    5. My result showed me in my book

  16. 1)We made sure everything was the same apart from the material we were testing.
    2)Chime bar,the size of the cup that we put the material in,same person.
    3)Material and the length we stood away from the Chime.
    4)we presented our data in a table and diagram.
    5)That Cotten wool was the best at insulating sound and carbroad was the worst insulating sound.
    6)No

  17. 1.We made sure that we were the same distance away from the IPad.
    2.The controlled variable was that we kept the materials the same.
    3. The independent variable was the distance away from the IPad.
    4.We represented our data in a table.This was not as affective because we could of used a bar chart.
    5.Our results showed us that the cotton wool was more affective.
    6.There was a lot of background noise.

  18. We made sure the test was fair by the same distance .
    Our controlled variable was what we kept the same so the sound and the distance.
    Our independent variable was the materials .
    We presented our by a table , it wasn’t really effective,we could have presented it by a bar chart .
    Our results showed that cotton wool was the best material and the paper was the worst material.
    Yes the background noise impacted the investigation.

  19. 1. We made sure that we were the same distance apart from the iPad.
    2. We kept the material the same.
    3. We made sure that we were one metre from the place we were.
    4. We represent our data in a table.No,we could have done a bar chart.
    5.Our results showed that cotton wool was more affective.
    6. There was background noise.

  20. 1.we made sure that it was a fair test by making the cups the same size,same length away and same background sound.

    2.we did not change the song.

    3.Our indepedent varibles was Tissue paper.

    4.So how we presented our data is that we made a table.

    5.Our results showed us that cotton wool was the best at ear muffing.

    6.I think having more than 2 items would be better so we can test if cotton wool is the best.

  25. 1. We made sure everything was the same apart from the materials we were testing.
    2.Chime bar,the size of the cup that we put the materials in,same person.
    3.Materials and the length we stood away from the chimes.

    2. Materials
    3. We kept the sticky notes the same place and the iPad. We also kept the sound the same.
    4. We presented our data by making using charts. We could of made a bar chart.
    5. It showed that cotton wool was the best material for ear muffs and paper was the baddest.
    6. The background noise could impact our investigation.

      • 1.we done it by making the same person hearing the sound and the person doing the voice.
        2.what we kept the same was the person hearing and th person doing the voice.
        3.what we will change is the material and the metre.
        4.We presented the data by doing it in a way.This was effective.we could change the time by making it longer.

    3.Our idependant variable is the material
    4.We presented our data in our table.We could’ve used data loggers next time.
    5.Our results showed that cotton wool was the best at muffling sound.
    6.The back ground noise affected our results

  44. 1.We ensured that it was a fair test by using the same volume.
    2.The controlled variable is the distance and the sound.
