|We blew through straws into water mixed with dish washing liquid. We created lots of bubbles which we learnt is filled with gas! We tried to pick them up...but they often popped. Why is that?|
We noticed that when we blew into water without any dish washing liquid the bubbles didn't stay. Our teacher told us that we breathe in a gas called 'oxygen' and we breathe out a gas called 'carbon dioxide'. They are hard words to remember!
Some of us went home and did the experiment at home with our families. Awesome stuff!
