welcome to my weebly :)
During my june holiday i went out with my friends to celebrate my friend birthday . We went to watch minion and after that we ate our lunch and went home
A)Red food colouring Orange food colouring Plastic bottle B)I use the knife and cut the stem after that I put food colouring inside the plastic bottle and put the flower inside C)my flower take a few hour to turn into a other colour D)cutting the stem might be very difficult E)the length of the stem and cutting the stem I have learn acid and alkaline topic . i think that this topic is fun and intresting . through the experiment i like the most is mixing the acid and alkali and see that become what colour , in acid and alkaline topic i also have learn the natural indicators . i mix the methyl orange with acid , alkali and the neutral substance . for acid it will turn red , alkali will turn yellow and the neutral substance id remain the same. the neutral ph level is 7 , i also learn that acid taste sour while alkali taste bitter .
the secret message experiment was cool . when we write the words with our frixion the words we write when missing when we put heat under the paper as the ink contain water . when the paper is heated up , the ink evaporate .
