We saved our little muck ponds all this time. Over the time we’ve observed them we’ve noted:
- ponds are stagnant
- muck is smelly
- things grow in ponds. The grass clumps continued to grow in the water.
- water evaporates
- the water became dirty because of what was in it
- without rain, ponds dry up
Since they were all dried up, I put them in Ziploc bags and sent them home. At home they can just add water for an instant pond. This was a great little activity that we will do again!
