This blog has been designed to provide information about the activities held at the social studies bilingual sections in CPI Tino Grandío (Guntín,Spain). The English language and Social Studies teachers have elaborated most of the resources you can see but our "auxiliares de conversa" also have their own page and posts. Therefore everyone is invited to have a look .

Our zebra fish

Zebra fish and their life cycle by María López Alonso

The female lays eggs in the water, where the male fertilizes them. The stages of embryonic development are fast.

The females lay more than 200 eggs per week. The embryos are protected by a membrane, the chorion. After three days the embryos hatch.
They can be kept in the laborature in culture dishes thanks to their small size.
An adult is approximately 4 incles long. Unlike humans zebra fish continue to grow until death.
