Today was my Bio SPA.
And kindof did wrong agn.
Forgot to use the boiling tube holder to hold the tube when burning the peanut.
Then was like "why so hot ah?"
My hand felt like burning.
Then Ms Rosy was pointing the tube holder rather glaringly.
Oops.
I redo that setup, but not sure if still will deduct mark.
When redo, the flame was rather great.
Then I felt the tube moving.
Then when I see inside the tube, it was boiling.
Check the temperature, its 100.5C.
Wow.
But i got 0.6g peanut tis time.
Quite drastic from my previous few setups.
Tmr is Physics SPA.
