Summarize the key points about the states of matter and the water cycle from a mind map titled "Materials around us".

Here are the key points from the mind map about "Materials around us":

• Every object and material is made up of matter.
• The three different states of matter are solids, liquids, and gases. Every object exists in one of these states.
• The state of matter can change. For example, ice (solid) changes into water (liquid) through melting.
• The water cycle involves four stages: evaporation, condensation, precipitation (rain), and collection.
