Understanding Sedimentation and Decantation

Jack conducts an experiment with muddy water, observing sedimentation as mud settles at the bottom of a beaker, leaving clear water on top. He then uses decantation to separate the clear water from the sediment. The video introduces sedimentation and decantation as methods of separating mixtures and hints at other separation techniques to be explored further.

What did Jack do with the beaker initially?

• He filled it with oil.

• He filled it with sand.

• He filled it with muddy water.

• He filled it with clear water.

What is the term for the process where mud settles at the bottom of a beaker?

• Filtration

• Evaporation

• Sedimentation

• Condensation

What is the layer of mud at the bottom of the beaker called?

• Sediment

• Residue

• Sludge

• Precipitate

How did Jack separate the clear water from the sediment?

• By filtering the water

• By boiling the water

• By decantation

• By using a magnet

What is the process of separating a liquid from sediment called?

• Filtration
