we were learning to create a animation about a volcanic eruption, I used polyline for drawing everything except the clouds because I used shapes instead.
I found it hard to make the fire coming out of the volcano because it always had a line through the middle so that was to hard to fix.
I found it easy to make the volcano and the lines to make it better.
next time I will make a shield volcano and the eruption will be different.
our task was to make lava lamps using water, oil, food colouring and pills it looked super cool with the bubbles floating up and up, the light made It glow and it was even more amazing.
The science behind it : the oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules, they get along fine as well. But the structures of the two molecules do not allow them to bond together.
We were learning to make a bath bomb for Mother's Day with was good because then we didn't need to go shopping and it would mean they would get more for Mothers Day.
I found it easy to combined the two colours together. It was also very cool watching the colours merging together.
I found it hard to make the colours to come out so you can see them.
Next time I will make it with different colors and try it with different salts.
I haven't used my one yet but Ms bava tried her one and it started to fizz and the reason is bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid.
