A oes gan geffyl fwy neu lai o werth na llyngyren neu deigr?

Or: Does a horse have more or less value than a worm or tiger?

Science, ethics and animals, our free secondary science interactive resource, is linked to GCSE science. It has been designed to support the science curriculum for 14 to 16-year-olds and encourages young people to think about the way we interact with, value and use animals in our daily lives.

The Ethics court and Value of life activities are now available in the Welsh language. Visit the Science, ethics and animals homepage, choose an activity and select the Cymraeg tab at the top of the page.
