This powerful student experience combines elements of geology and basic chemistry, and the materials are easily accessible. In this exploration of rocks, rock types, and all their different features, students will use acid to help identify the minerals in front of them. The packets include dozens of question cards as well, which makes it a comprehensive resource. Plus, the worksheets feature little pockets where they can collect samples and mineral cards of each type of rock. With this bundle of rock activities, your students will be able to identify different types of rock. These eighteen activities can help you break down the rock cycle for elementary and middle school students to better understand! 1. Elementary-aged students and middle school students are usually the ones learning about the rock cycle, so it’s important to incorporate some hands-on activities into your lessons so that the concepts of the rock cycle really stick for them. They will develop analogies for how processes that they use in the classroom (like pressing the crayon shavings together or heating them on a hot plate) relate to processes that occur within Earth, such as lithification (the process in which sediments compact under pressure) or heating from Earth's core.Teaching the rock cycle to students is an important step in teaching them about geology and the world around them. From there, students will explore how they can turn their sedimentary rock into other types of rocks, and whether they can change the other types of rock back. These crayon shavings can be compressed in layers to form a sedimentary "rock". First they will use a sharp kitchen utensil (like a knife, potato peeler, or cheese grater) to make crayon shavings. In this lesson plan, your students will develop a model for the rock cycle using crayons. The rock cycle, showing how sedimentary, metamorphic, and igneous rocks can each turn into the other types. Rock cycle diagram showing igneous rock, metamorphic rock, sedimentary rock, and magma with the following transitions: All three types of rocks can turn into magma by melting Magma turns into igneous rock by crystallizing Igneous and metamorphic rocks turn into sedimentary rock by erosion, deposition, and lithification Igneous and sedimentary rocks turn into metamorphic rocks by metamorphosisįigure 2. ![]() When magma cools-either when it crystallizes below Earth's surface, or when it emerges through a volcano and is exposed to water or air-it forms igneous rocks. Rocks can be melted by the high temperatures beneath Earth's surface, forming magma.This deforms them and turns them into metamorphic rocks. Rocks can be heated and compressed by the high temperatures and pressures under Earth's surface in a process called metamorphism.These pieces accumulate to form layers ( deposition), and are gradually compressed ( lithification) to form sedimentary rocks. ![]() Rocks can be broken into smaller pieces by weathering and erosion.Note that while distinct layers are clearly visible in the sedimentary and metamorphic rocks pictured here, that might not always be the case.Įach type of rock can turn into other types of rock through various processes within Earth or on Earth's surface (Figure 2). From left to right, examples of the three types of rock: a sedimentary rock, a metamorphic rock, and an igneous rock. Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.įigure 1. Models can be used to represent systems and their interactions-such as inputs, processes, and outputs-and energy, matter, and information flows within systems. The energy that flows and matter that cycles produce chemical and physical changes in Earth's materials and living organisms. This energy is derived from the sun and Earth's hot interior. ![]() This lesson focuses on these aspects of NGSS Three Dimensional Learning: Science & Engineering Practicesĭevelop and use a model to describe phenomena.Īll Earth processes are the result of energy flowing and matter cycling within and among the planet's systems. This lesson helps students prepare for these Next Generation Science Standards Performance Expectations:ĭevelop a model to describe the cycling of Earth's materials and the flow of energy that drives this process. Explain how crayons can be used to model the rock cycle.Understand the cycling of matter that forms rocks inside Earth and on Earth's surface.Can they turn a sedimentary "rock" made from crayon shavings into a metamorphic rock? What about an igneous rock? Try this lesson to find out! Can one type of rock turn into another type of rock? In this lesson plan, your students will explore the rock cycle and model it using crayons.
