Master Sand sculptor Sandi “Castle” Stirling has been educating and entertaining Grade 4 students in the Hamilton-Wentworth schools since 2002 with her exciting “Sandi Castle Presentations”. She has developed a fun and unique way to introduce Medieval Times and/or Rocks and Minerals to the students through the use of visual displays, videos, creative imagery and the creation of a 3 foot Medieval looking sand castle keep. This fast paced information packed presentation keeps the students enthralled for 90 minutes. While most of the focus of this presentation is on sand, the class will be introduced to different types of rocks and minerals. Igneous, sedimentary and metamorphic are discussed and displayed along with samples of fossil rocks from Lake Erie, coal from Atlantic City Beach, lava from Hawaii and soapstone from Brazil. The class explores why some beaches have stones on it while others have soft sand and how beaches are formed. Sandi shows how erosion from single drops of water over a period of time can break down a rock into sand. In an entertaining way, she pulls consumer products made from sand out of a bag. She also identifies the many uses of rocks in manufacturing.
