None of these two leaders would have supported science education for black children. In fact, the Eiselen Commission on Native Education in 1949 recommended the intensification of reforms in black (Bantu) education. This Commission was appointed by government to investigate aspects of native education. Among others, the Eiselen Commission pointed out that Bantu Education is different from education and it was established to ensure that it fits into the doctrine of white supremacy. "The African must understand that European civilisation in its broadest sense is closed to him, and his learning of culture must be confined to the primitive culture of his life in the reserves" (Federation of South African Women, 2013:2). Today, in historically black schools, teachers are still faced with the challenge of demystifying science and in a time of decolonisation debates, explore ways of injecting African indigenous knowledges as well. As cited by Msila in the Preface, Macedo (1993) discusses the Pedagogy of Big Lies, which points out that poor children cannot succeed in school because of their socioeconomic status. Yet when people speak of decolonisation, they seek to see schools as correctors of socioeconomic equality and social injustices (Bude, 1985). Historically, black children in historically black schools have not fared well in Mathematics and Science and this is no wonder when one looks at the objectives of apartheid education highlighted above. In the past unqualified and underqualified teachers taught these subjects due to a shortage of qualifies teachers in these learning areas. In historically black schools today, many teachers may believe in the pedagogy of big lies; that learning areas such as Mathematics and Science are not for poor children because of their low social capital. The objectives of this chapter are to explore how a decolonised system has a potential of demystifying science, thus making it relevant to the learners' life world. The chapter seeks to investigate the role that can be played by Indigenous Knowledge Systems and linked to this is language, which is usually seen as a purveyor of culture. The use of the learners' knowledge from home can be beneficial for not only Science but also all knowledge in schools. Naidoo and Vithal (2014) point out that, in South Africa, Indigenous Knowledge Systems (IKS) play a critical role in Natural, Physical and Life Sciences and they are part of the Department of Basic Education's policy. Furthermore, these authors claim that the inclusion of IKS provides motivation and self-esteem, cultural responsiveness and relevance, increased peer interaction, as well as positive learning experiences. Van Wyk (2002:311) perceives a new space for IKS in South African schools today as he avers:
