Year 4 Science: Investigating Condensation!
Year 4 have been busy little scientists! We carried out an exciting experiment to investigate what happens when a warm cup is covered with an empty plastic cup.
We watched carefully as the warm cup was covered with the empty plastic cup. We looked closely to see what was forming inside the top cup. We observed tiny water droplets appearing on the inside surface!
We learned that some of the liquid water evaporates and becomes water vapour. When the water vapour cools as it touches the cooler plastic cup, it condenses and turns back into liquid water droplets.
We used our key vocabulary to help us explain our observations:
Evaporation – when liquid water changes into water vapour.
Water vapour – water in its gas state.
Condensation – when water vapour cools and changes back into liquid water.
Water droplets – tiny drops of liquid water.
After our investigation, we drew and labelled what we had observed, using the key vocabulary to demonstrate our understanding.
