Elephant Toothpaste

Image
For Immersion on Wednesday we made Elephant Toothpaste, Elephant Toothpaste is chemical reaction that makes an explosion of foam. Elephant Toothpaste is made with Yeast, water, hydrogen peroxide, dish washing liquid and you can add food colouring  if you like. This is what it looks like--------------------------------------------------------------------> After we did the normal Elephant Toothpaste we tried changing some things like more yeast, less water and smaller bottle. we got into groups, each group changing something different, my group added more yeast and the results were that it didn't make much difference except that when we tried to put the yeast in it turned into a paste, like peanut butter. Elephant toothpaste is a chemical change because it is irreversible, it is an explosion of foam and it bubble and those are some reasons why it is a chemical change and not a physical change.

Science in a van

On Thursday we had Science in a van, Science in a van is two people who teach children and adults about science. At the start of the day the whole school went to the front of the school and watched the show; first they put a table cloth and cups on top of the table cloth onto a table and quickly pulled down the table cloth so that the cups stayed on the table. Next he had a piece of cardboard with strings on it and he put a cup on top of the cardboard and spun the strings around, surprisingly the cup didn't fall off. Later, in the last block   all of LC7 went to Lc5 for science in a van. we learnt all about the periodic table and solids, liquids and gas we also learned about insta snow which is a powder that can soak up about 4 times its velocity. Thanks for reading my blog post bye!
