WALA: Investigating evaporation

1. Water evaporates more quickly from the container in the warm place than from the container in the cool place.

OR

More water evaporates from the container in the warm place than from the container in the cool place.

2. A line graph. Line graphs are used when there is smooth change or progression in the factor being measured over time, such as volume of water evaporated or an increase in temperature or plant height.

3 a). Evaporation happens more quickly when it is warm.

b). Repeat the investigation several times.

4).Instead of putting one container in a warm place and the other in a cool place, you could let a fan blow onto one container but not onto the other container.
