I really like how teacher how put the whole idea up on the computer and let us learn and have fun at the same time, I understand a lot more after that lesson.It has made me understand the energy better for example; kinetic energy and potential energy, I think it is very meaning for me to attend that lesson.
The experiment was quite difficult for me at the beginning as I have difficulty with the stop watch but as I keep on trying I became more and more comfortable with the materials used.This experiment is actually very easy and meaning, it have made me more understand who a pendulum work, although there is a little set back at the beginning but I still manage to complete the experiment and also gain a lot of knowledge about pendulum.
The color slowly change in the flower,this was what I observe.
Equipment list ![]() 20 photos every hour Photo with my flower 1st step:Pour in the color dye into 3 cups or cans. 2nd step:Trim the stem of each at an angle to create a fresh cut. 3rd step:Use a scissor or knife and cut the stem into parts of thee. 4th step:Place the three parts of stem into the 3 cups or cans. 5th step:Checked it every hour to see how things is processing. I cutted the stem of the flower into two instead of three and there is not enough space to cut for the third one,so I had to buy the flower and redo the whole experiment.Also the color of the flower didn't change at the first few hour but it changed later but not visible. From what I think,schools can provide us with a few more carnation so after we failed the experiment we could redo the experiment again and find out what the problem was during the previous flower,school can also send us the link to download the motion app.
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.
