Cute???

To me, it's cute~ Hehe
Me n Aina's masterpiece for Bio~
We did this experiment under respiratory system..
Straws as trachea, de part which is divided into 2 is de bronchus, de balloons is de lungs, de gold base is de diaphragm... De bottle is for de thoracic cavity~

See how de balloons deflated when I pushed de diaphragm up?
It is cause by de high pressure in de thoracic cavity..
This represents exhalation~
See how de balloons inflated when I pulled down de diaphragm??
This shows de low pressure in de thoracic cavity...
De low pressure in de thoracic cavity will cause de higher atmospheric pressure to press down de air into de straws, all de way into de balloons....

De ice-cream sticks represents de backbone, stanum, and rib cage...
De rubberbands represents de internal intercostal muscles n de external intercostal muscles....
This shows that de external intercostal muscles r relaxing when de internal intercostal muscles contract

This is de opposite~ De external intercostal muscles contract while de internal intercostal muscles relax~

This is de back view..
Pn Yong asked us to put plasticine so that de thumbnails wont injure us~

These r de bangles I get from Hari Koko~







This is de cookie me n Aina sold during Hari K~
We sold 3 containers of cookies within an hour..
Actually we finish selling them around 45 minutes or less than that~
Miss Jessica n de other teachers were all praising our cookies~
Cos it was really delicious...
When Mr Justin tried our cookies, my fren was saying that there's poison..
SO when he put it in his mouth, he immediately did a reaction n act like he was choking on it..
So evil rite???
