Limestone and its uses Fact Relay

Pupils split into groups and given textbook.1 person from each group comes and picks a question card from their group's envelope of questions and takes it back to their group. They all look for the answer in the book & write it in answer sheet. Another member of the group comes and tells you the answer, if right let them pick another Q. First team to answer all wins. Covers: uses of limestone, cement/concrete/glass production and advantages and disadvantages of quarrying (I follow with first 2 minutes of the attached video). Designed for weak group who hate reading but love competition
