if you had taken IB, what would your ee topic be?
How effective insect repellent is on Mosquito's!
You have the coil, the cartridge (keping-keping of those rectangular things), the liquid type, the sticky paper with attractive insect smell and colour, the aerosol spray (different propellants), those commercial ones for outdoor where you put on your body, woooww so many.
We can test it on real humans and see if they get dengue or we can use a rat. The rat might die of the poison but who knows? It is either you get bitten, don't get bitten, mosquito dies. Measured in a box or something. But whatever. Its just coming out this way.
