This January students from the Albany Free School, a Waldorf  homeschool group, and the Troy Produce Project visited the Radix Center.

They learned about the how the sun heats the greenhouse, and lets so many different things live inside – and explored:

How worms eat food scraps and give us valuable fertilizer –

The difference between bugs that eat our food plants (aphids)  and bugs that eat those bugs!

We set 1000 ladybugs free to attack the aphids.

Saw the different  fish that live in the big tank using the aquascope-

And how the fish and the plants live in a symbiotic system together – as the aquatic plants act as nature’s filters to clean the fish waste, and use its nutrients to grow.
