Abstract：
Central to What Babies Know (Spelke, ) is the thesis that infants\' understanding is divided into independent modules of core knowledge. As a test case, we consider adding a new domain: core knowledge of substances. Experiments show that infants\' understanding of substances meets some criteria of core knowledge, and they raise questions about the relations that hold between core domains.
