About this reader

This 250-word reading passage introduces fourth-grade students to the observable properties of rocks, aligned with NGSS standard 4-ESS2-1 and DCI ESS2.A. Students learn that rocks come in many different forms and can be described by their hardness, texture, color, and structure. The passage explains how some rocks are hard while others are soft enough to scratch with a fingernail, how texture varies from rough and gritty to smooth, and how rocks display different structures including visible layers, crystals, and cemented pebbles. Students discover that rocks come in various colors including gray, red, white, black, and brown. The passage emphasizes that scientists and students can sort and compare rocks by testing hardness, observing texture, and noting color differences. Audio-integrated features support diverse learners. This foundational earth science content prepares students for hands-on rock classification activities and builds understanding of Earth's materials and their properties.
