balloon rocket!

                               Balloon rocket

For this experiment we used: paper straws, balloons, string and tape!

One person went to get the tape, and one person blew the balloon, and one person went to get the straw and the string.

First of all we cut the straw in half and added it to the string, and then we put tape on the balloon so it would stick to the straw. But the balloon wasn't tied so I held it so the air wouldn't go out .

Then I let the balloon go, and it zoomed through the string, all the way to the other side.

I learned about lawtons three laws of motion

I enjoyed letting go of the ballon and watching it zoom through the string 

I found it easy to cut the straw the right size

I found it hard to blow the balloon the right size

Milk explosion

      

Milk explosion

First we had the ingredients which was dairy milk sanitiser a  cotton bud and dye 

One person went to  put sanitiser on the cotton bud then somebody put the milk in the bowl and then we went on the deck and put the dye in the milk and then we dipped the cotton bud in the milk.

And then all the spread away from it wherever we put it!!

I enjoyed putting in the cotton bud

I found it easy to put the right amount of dye

I found it hard make sure we didn't dip the cotton bud to far into the milk  

Bath bombs

                                          

We had to make bath bombs using dye citric acid and salt and some other wet ingredients

First of all we had the mixture in the bowl then we had to mix it then we chose  our colouring,then we shaped into a ball and put it in the mould. 

This happens because 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.

I found it easy to mix the ingredients

I found it hard to mould it because sometimes it kept falling apart

I enjoyed putting in the dye

Next time I won't put so much dye
