Make or buy some bubble mix. To make, mix one part washing up liquid to six parts water.
Think of the people and situations in the world you want to pray for and, as the bubbles float up and away, imagine your prayers going up to God.
Notice the fact that each bubble is unique. Thank God for making each member of his global family unique and pray that all people may have what they need to live.
Make a gauge to measure how much rain falls where you live.
Recycle a plastic bottle by cutting off the top and placing it upside down in the main body like a funnel. (Be careful it might be sharp so adults might want to do this part)
Use a ruler to measure and mark every centimetre on the bottle with a marker.
Securely bury the rain gauge, away from trees, in a place where it can catch a lot of rain.
When you go to check it, say a prayer of thanks for the way water renews the earth. You could use these words from Saint Francis of Assisi:
Praised be you, my Lord,
through Sister Water
who is so useful,
humble,
precious,
and pure.
