balloon madness

 last week we were learning about action and reaction. we were doing an experiment when we get baking soda and vinegar we put the baking soda in the balloon and the vinegar in the bottle so when we put the balloon on the bottle and pour the baking soda in it makes action and when the balloon blows up that is called a reaction. so when it blows up it is because the reaction is trying to let out carbon dioxide (bad air) 

the action and reaction thing is newton's third law

here is a video

i found it hard to figure out the science behind this because i never knew about newton's third law  

i observed that when there is action there is a reaction 

balloon madness

last week we were learning about isaac newton's third law and when there is action there is an equal or opposite reaction. we taped a balloon to some straw and then put the string through the straw so when we blew it up the action made a reaction. here a some pictures.  

try it at home all you need is tape,a straw and a balloon

i found it hard to get it to move at the right speed because each angle has a different reaction and it depends on how much air is in the balloon

i found it easy to get the balloon moving because the less the air the faster because when it has lots of air it using heaps of pressure to slow it down 

Persuasive writing 2021

 

today we were learning about being prepared for a natural disaster and if it is important or not. here is what i think but maybe some people think different.

i found it easy to choose if its important or not because i know that this is what i would do.

it was hard to write this because i had to think of reasons and have evidence which is hard.

next time i will try to describe the work a bit better but here is my mahi i tried my best. 

Today we were learning about Molecules - Fatty acids, soap & minerals. it was very easy figuring out the sience because i had done something like this before.

it was hard to make the colours combine so it would be cool but i did it.

next time i will try to make it out of different soaps and milk to see if it changes
