We have been learning about the rock cycle in South Casa. We read about and discussed how igneous rocks are formed through the cooling and solidification of magma; how sedimentary rocks are formed as sediments of those rocks are put under pressure over many years; and later, metamorphic rocks are made from pre-existing rocks. After learning about this process, we were then able to have a better understanding of how fossils are made over thousands of years through the same pressure and time it takes as the rock cycle. We used a fossil digging kit to explore the care it takes for archeologists to carefully dig up bones and plant remains to preserve the fossil. Each child took a turn digging and dusting off sediment to uncover 15 different fossils. We read about each one and what they previously were, such as shark teeth or coral.
