Science Week Homework

Have a go at one of these experiments if you can, and write about it on the blog:

Can’t remember how to write up an experiment?

Here’s a reminder:

  • Equipment  – What did you use?
  • Method – What did you do?
  • Predicition – What did you think would happen?
  • Results – What actually happened?
  • Conclusion – Can you explain why it happened?

    Making a vinegar volcano

    When the baking soda goes with the vinegar it makes a carbonic acid then it breaks apart into water and carbon dioxide.Which makes the fizzes to escape.

    Making music with cups

    Each of the glasses have a different tune the one with the least water will make vibration the one with the most water will make a least vibration with the pencil or stick.

    Hi Mrs Holland
    I tried the second experiment.

    Equipment :
    5 or 6 same glasses
    Water
    1 or 2 wooden spoons

    Method:
    First I poured different amounts of water into the 5 glasses (least amount to the most)
    Next I lined up all the glasses in one row.
    Then I got the wooden spoon and turned them around so I could use them to bang on the glasses.
    After I hit the Spoon on the first one then on the last one.

    Prediction:
    I predict that the one with the most water would make the highest sound because when you hit the glass there was a bit of space so then the sound quickly comes out and spreads and the one with least will take longer for the sound to come out.

    Results:
    The actual thing that happened was that the one with the least water did make the highest sound.

    Conclusion:
    This Happened because vibrations were made and the more vibrations the higher sound.
