Eco Column

This week Lisa made an Eco Column with the boys for science lesson.
They used three two-liter bottles to create it.

In the bottom there was gravel and water plates, distilled water and two fish. The fish were named: Darth Fishy (it was black (yes past tense)) and Luke Fishy who is gold.



The joy of putting in the fish.




In the top portion is an inverted two-liter bottle. It has gravel and then dirt - which they planted seeds in, and three crickets. The extra moisture form the cricket portion can drip down and give the fish more clean water.

The fish can eat the plants, create fertilizer for the plants. The plants give off oxygen and take in carbon monoxide. Cool. Kind of the same in the top, crickets eat the plants that grow from the seeds that were planted, create fertilizer. It really is cool how it all works.

But one of the fish has already died.

The kids love it though and they love to tell people all about it.
