I am a bit confuse during this experiment, I just follow the instruction give in the worksheet and do the experiment.After the experiment,my teacher explain the experiment to the class and I finally understood the experiment.Although my team didn't finish the work but we get to see crystal from the other group,the crystal is very shiny.My team didn't get to finish the experiment because we have done the wrong step and have to redo all the experiment,maybe if my team haven't done the wrong thing we might be able to see the crystal in our very own experiment but I don't blame them because
Title:Diving Ketchup
This experiment is simple you just need a packet of ketchup,a plastic bottle and water to do this experiment but I have learned a lot from this experiment.I have learned that pressure act inside water too and how are volume and pressure related,when pressure decreases,the volume increases. After reading the core notes and doing the experiment I finally know what is acid and alkaline.Actually we all do use acid and alkaline in our daily life,things like vinegar(acidic),sodium fluoride(acidic),soap(alkaline)and vegetable(alkaline).You can test out if an object is acidic or alkaline or even neutral using many different kind of indicators example:Litmus paper,phenolphthalein,methyl orange,universal indicators and pH meter(with data logger).I find this experiment fun and also interesting and now I have more knowledge.
This is my first time doing this experiment,it was interesting watching the colour changing to many different colour.I have learned that paper chromatography can be used to separate small amounts of mixture and know I know where do colours come from.
