Children return to school Mon 8th April

This afternoon in year 5 we were investigating gas produced when we dissolved solids in liquid. We looked at the gas made when we dissolved vitamin C in water. 

We did this by putting vitamin C tablets in film canisters and adding water – the shot to the sky like rockets.

What variables did you change?

What did you keep the same?

What did you notice?

How did you make sure the test was safe?

    1) The variables we changed were the tablets.
    2) We kept the containers and the water the same.
    3)I’ve noticed that when we added the water we put it on the ground upside down and it started to fizz.
    4) We made sure that the experiment was safe because when we added the water and the tablets we moved back.

    We kept the container the same.
    The object we changed was the water.
    I noticed that when the container was upside down the water turned orange and bubbles came out from underneath the container and went on the floor.
    We made sure the test was safe because we stood back and didn’t go near the container when it was on the floor.

    We changed the amount of water. We kept the amount of vitamin C tablets the same.

    We changed the amount of the tablets and the water.
    2.)what did you keep the same?
    We kept the containers the same size.
    3.)what did you notice?
    I noticed that the more less water we put the quicker it exploded and it went really high.It goes really fast.
    4.)how did you make sure that the test was safe?
    We made sure that the test was safe by stepping back and not going near it.

    1) The only variable we changed was the amount of vitamin C tablets.
    2)We kept the amount of water the same.
    3)We noticed the more vitamin we added the quicker the reaction was.
    4)When tipping the container over we stepped away from it so that we didn’t get hit.

    1) We changed the amount of tablets and water.

    2) We kept the container and temperature the same.

    3) The less water there is the more time it takes but the more gas there is the more higher it goes.

    4)Everytime someone put the lid on and they put it down they would have to step back this is how we made it safe.

    1) We changed the amount of Vitamin C tablets adding more tablets each time (three was our highest amount)
    2) We kept the same amount of water.
    3) We noticed when you add 3 or more the lower it explodeds and when you add 2 or 1 it explodeds higher .
    4) We made it safe by stepping away from the capsule before it exploded.

    As a group,we changed the amount of the vitamin tablets .The quickest was the the last one and there was one and a half vitamin tablets.We kept the amount of water the same.i noticed the more vitamin,the shorter it takes.To make the test safe we stepped back from the canister after we put the lid on tight, but some people put the lid on but they did not ind they thought they did but it was so close to exploding in his face,so keep away even if it look like its not going to explode

    My group changed the water sizes to observe which water amount shot into the sky
    the fastest.we kept the vitimanC tablet amount(2)the same to make it a fair test.i noticed that the one that had the least amount of water lost.

    We changed the amount of water and the amount of tablets .
    2)we kept the blu tack and the lid the same.

  14. Fatima G.

    Sorry for the spelling.We typed too quick!

    1)We changed the water level to average then a little bit of water and abit had like times the other .
    2)We kept the size of the tablet(vitamin c) all the sane size and did not use any other type of tablet in our investigation that we carried out in the field in groups.
    3)We noticed that we did not do it properly so we did not see the results.We di see two but they were very low compared to the other groups investigation.
    4)We made sure that the test was fair by putting the same amount of tablets (vitamin c) and the film canister was all the same size.

    1)We changed the amount of vitamins.
    2)We kept the capacity of water the same.
    3)The more vitamins we put in, the higher it exploded. We also tried reusing them.
    4)We stepped back when we put the canister onto the ground.

  17. Pranay K.

    1)The variables we changed was the amount of water and the number of tablets.
    2)The variables we kept the same were the canister’s size the same and the lid.
    3)We noticed that the less the water, the more space gas can take up and so it takes longer for it to pop but it goes longer.
    4)We made sure the test was safe by quickly moving away after putting the canister on the floor. We also followed the health and safety rules.

    The variables we changed were
    The amount of tablets
    And also changed the amount of water

    The things we kept the same were
    The canester
    The tablets
    The the water

    What did you notice
    We noticed that when you have less water there is more room for air which makes it go higher also when we had a lot of water it took longer for it to explode

    Did you make sure the test was fair and safe
    Yes because when we set it we stood 4 or 5 feet away from it so it doesn’t explode in our face

  19. Zabit M.

    1)We changed the amount of water and tablets.

    2)we always kept the container same throughout the whole session.

    3)we noticed that the less water you have it goes higher because there’s more room for gas. But two tablets just made it explode faster.

    4)we made sure by putting the canisters in the middle and we ran back to our groups.

    When we watched miss Cochrane do it we change the amount of water and the amount of tablets but it didn’t make much of a difference.
    I noticed that when we added less water with one tablet it went much higher because it has more air space to build up air pressure and gas to explode.
    We didn’t really make sure it was safe but the thing we made safe was we took it in turns to make it explode because we all had to stand back just in case the experiment went wrong.

  21. Hafsa A.

    We changed the amount of water and the amount of the tablets. We noticed that when we put less liquid the container went higher but it took longer than the normal ones. We made sure this was a safe test as we all stood back.
