Mulzer Crushed Stone, Inc. brought their R.O.C.K. Ambassador program “Mining 4 Fun” to the 3rd grade students at E. Heights Elementary school in Henderson, KY last week. Bob Lingerfelt, QA/QC Manager at Mulzer Crushed Stone, Inc. delivered a presentation to the students about aggregate products and geology in general. The students were asked to become rock detectives during an activity designed to make them think about the properties of rocks and minerals and why that is important in building things like roads and highways. The students and Bob had a great time learning about all the wonderful things that aggregates are involved in!
