Which state of water has a fixed shape and does not flow?

Explain It

Descriptive question on the cooling effect.

Answer the following question in your own words based on what you've learned about states of water.

We see green coloured plastic grass at many places these days. Space around natural grass feels cooler than space around the plastic grass. Can you find out why?

Why does natural grass feel cooler than plastic grass?*

Focus on: the role of water and evaporation in creating a cooling effect.

The Fan Paradox

Socratic chat about drying clothes with a fan.

Learners can ask follow-up questions and keep the thread going.

This is an analysis question about the conditions that affect evaporation. Fans make us feel cool, but we also use them to dry wet clothes faster. To understand this paradox, let's start by looking at the air right next to the wet clothes. As water evaporates from the clothes into that nearby air, what happens to the amount of water vapour (humidity) in that specific patch of air?
