Project 3


Students will spend half a day on Project #3A and the other half of the day on Project #3B.
Project 3A Title:         The Fastest Ball Challenge
Project Source:
          School of Physical and Mathematical Sciences (SPMS)
Project Supervisor:  Dr Ho Shen Yong
Teacher Advisor:
      Ms Audrey Tan (tan_sze_ghee@sst.edu.sg)

Descriptions:

Students will learn the concepts of conservation of energy, kinetic and potential energy. They will also learn how to use photogate sensor for data acquisition. In this challenge, students will set up an apparatus consisting of a ramp hinged at the edge of a track such that the angle of inclination can be varied. Using a smart timer and photo-gates, students will record the time taken for the ball to travel across the distance of track. Students will determine the angle of inclination for which the time of travel across the horizontal track will be least.

Project 3B Title:        Extraction of Caffeine from Beverages
Project Source:
         School of Physical and Mathematical Sciences (SPMS)
Project Supervisor:  Dr Alessandra Bonanni
Teacher Advisors:    Mr Ng Guohui (ng_guohui@sst.edu.sg)
                                       
Descriptions:
Students will learn about caffeine which is a type of alkaloids. Caffeine is a stimulant found naturally in tea, coffee and kola nuts. Other examples of alkaloids include cocaine (a drug of abuse), strychnine (a poison), morphine (a pain killer), piperine (found in black pepper) and quinine (used to treat malaria and added to tonic). Clearly some alkaloids are beneficial and others extremely harmful. In this project, students will learn how to extract caffeine from different beverages.
