Bioreactors, earthworms, fish cradles
Last Science Club wasn’t different from previous ones, as we were busy outdoors again. Whilst the girls took water samples from our pond and were examining that, the boys replaced the pond foil and poured clear water into the bioreactors, made of old tires, in which we breed the food of our fish. The number of our water fleas has grown by leaps and bounds thanks to Peti bácsi and to our team, so now we can feed our fish on natural food. Bella and I planted the ipomoeas while the boys wed out the garden so that now we don’t have to worry about peas. Sadly, our earthworm farm got spoiled due to the heavy rainings, however, we could keep four buckets out of the five in which we could still find a large number of earthworms.
