GEOLOGY AND ROCK COLLECTINGDuring Spring Break, national award-winning Grapevine 5th grade science teacher Krystyna Plut made our Next2Nature class "rock"! We never knew that rock-collecting and geological formations around Grapevine Lake were so interesting.
Krystyna passed around common sedimentary rocks filled with marine life shells that she had collected around the lake, and taught the class how to test rocks for calcium deposits. She continued to introduce all types of rocks -igneous rocks formed by hot lava, and metamorphic rocks whose minerals change during time and extreme environments.
Campers also had a hundred questions about all the samples she brought, as well as the hadrosaur, a duckbilled plant-eating dinosaur that lived about 96 million years ago in Grapevine. The tracks—imprints several inches deep in the sandstone bedrock were discovered on the north shore of Grapevine Lake in 1982. The Corp of Engineers office on Grapevine Lake still has a mold of that original footprint on display.
The class ended with a really fun nature craft! Guests made 'Rock Critters' with smooth river rocks, pipe cleaners
and big eyes. Everything from snakes, bugs, spiders, butterflies, frogs and many unknown creatures creatively were glued together.
Rock collecting will never be the same...
