What did you do today?I went to the SPCM with my group mates and we did the fastest ball challenge and extracted caffeine from tea bags.
For the fastest ball challenge, we had a ramp, photogates and a metal ball. We had to find the conditions that would make the ball roll the fastest by changing the angle of inclination. There was an additional challenge which we had to find the angle of inclination and position of the ball which made the time taken to roll through the two photogates 1 second.
For the extraction of caffeine from tea bags, we had to use various methods in the Chemistry Lab to extract the solid caffeine from the tea bags. Such methods include Büchner filtration, Solvent extraction and Distillation using a rotary evaporator.
