Activity 1.3 Put an unlit incense stick in a corner of your class. How close do you have to go near it so as to get its smell? Now light the incense stick. What happens? Do you get the smell sitting at a distance? Record your observations.
for the first one you have to be very close to smell it, when lit the aroma fills the class because there is no ventilation and how there is no way for the gas to leave the room
