01 / UNDERSTAND

Here is what is happening.

Water can be solid ice, liquid water or water vapour, a gas. Evaporation changes liquid into vapour; condensation changes vapour into liquid. Water vapour itself is invisible.

Pause. Make the idea your own.

Explain one idea to a partner, draw it or write it in your own words. Which part is an observation, an example or a question?

You can use a home language. No need to share personal experiences or finish everything in one sitting.

02 / MAKE IT YOUR OWN

Your little investigation

What you need

A plate, a few drops of water and paper. No flame or hot water.

Spread a few drops on a plate. Draw what you see.
Leave it in a safe place and check later; drying time varies.
Draw arrows between ice, water and vapour. Name the changes you know.

03 / CHECK YOUR UNDERSTANDING
