- The investigation of the amount of radiation the types of cellphone gives out
- The investigation of the best material which could block radiation
- The development of a pet-feeder
- The investigation of the effect of different anti-bacterial agents on bacteria
There were many reasons why the initial ideas were not chosen.
Idea 1: We felt that the amount of radiation measured was not exactly easy to measure, as we had many other minor details to take note of.
Idea 2: We found out that as long a material could block radiation, 100% of radiation would be blocked, and thus the experiment would be invalid.
Idea 3: The pet feeder was not based on any particular science concept.
