Could you please explain, while doing worshiping, according to Hindu Mythology, why do people produce smoke through burning joss sticks; light a candle-like light called "Dip jyoti" prepared from cotton-swab and mustard oil or margarine; and ring a metallic bell (made up of alloy of brass and iron) and while doing so all the three items (joss sticks, light, and bell are moved around the "Almighty" in clock-wise direction? This is related to the "Science and Environment Conciousness".
