Now to the part in Biology Lab. Sarah was having her tennis tournament so there is only Shennen, Joyce K and me as lab partners (we are lab partners for Chemistry, Biology and Physics). The experiment today was about studying osmosis using an osmometer. The experiment included a syringe with the needle still on (boy,the needle was so long and so sharp!) so Joyce and me were so sakai with the syringe. We sucked water in and we sprayed water out. == The experiment wasn't so successful. Do you want to know why? We secretly manipulated the experiment. After we (Joyce and me) found out that there were air bubbles present in the capillary tube, Joyce decided to use the syringe to suck the air bubbles out. Who knows, the sucrose level in the capillary tube rose too. It was so high that I used the syringe and pumped air into the capillary tube to lower the level. It was an unwise decision. We ended up with no sucrose solution in the capillary tube. After a few minutes, I decided to use the syringe to suck some air out of the capillary tube so that the sucrose solution in the capillary tube is at the initial level. Laugh out loud. The best I can do was 0.8cm from the initial level of the sucrose level. I think that our group has the highest level. == We manipulated it too much. :O Never put us near a syringe.
Oh! Oh! And the time when my brain is shutting down is around 2.45pm until 3.50pm on Tuesdays. I can barely keep my eyes open during tuition today. So stupid. I think half of my brain was already sleeping.
That's all for now. XD How I wish there will be no Chinese class tomorrow. Just like last Wednesday.
