You can collect quantitative data by measuring the change in mass of the dialysis bag before and after placing it in water. Water diffusing into the bag will increase its mass as it moves from an area of high to low concentration. By calculating the difference in mass over time, you can graph the rate of water diffusion into the bag.
rain water collected from roofs of houses,making tanks,etc.
Carbon dioxide is collected by downwards delivery because it is denser than air. When collected, it displaces the lighter air above it and has a tendency to sink, making it more efficient to collect and contain in this way.
Oxygen gas is collected over water because it is not very soluble in water, so it will not react with or get absorbed by the water. This allows for a pure sample of oxygen gas to be collected.
Hydroelectric energy can be collected anywhere that water can fall. Water is usually collected from higher elevations and made to travel down long pipe sets to water turbines that convert the potential energy of the water into electricity.

Archimedis was so deep into thought that he filled up his bathtub full before he climbed in. When he climbed into the bathtub, the water spilled out of it and on the bathroom floor. He then realized that his mass caused the water to spill and if he collected the water and measured its mass it would be the same as his mass. He ran out of his house without wearing anything saying EUREKA!
