WA.2. Inquiry (INQ)
6-8.INQ. Questioning and Investigating: In prior grades students learned to plan investigations to match a given research question. In grades 6-8 students learn to revise questions so they can be answered scientifically and then to design an appropriate investigation to answer the question and carry out the study. Students learn to think critically and logically to make connections between prior science knowledge and evidence produced from their investigations. Students can work well in collaborative teams and communicate the procedures and results of their investigations, and are expected to critique their own findings as well as the findings of others.
6-8.INQC. Investigate: Students know that collecting, analyzing, and displaying data are essential aspects of all investigations.
6-8.INQC.1. Students are expected to communicate results using pictures, tables, charts, diagrams, graphic displays, and text that are clear, accurate, and informative.
WA.4. Earth and Space Science
ES2. Earth Systems, Structures, and Processes
6-8.ES2. Cycles in Earth Systems: In prior grades students learned how Earth materials change and how they can be used for various purposes. In grades 6-8 students learn about planet Earth as an interacting system of solids, liquids, and gases. Solar energy powers the water cycle and drives the weather system and ocean currents. Energy from within the planet drives the rock cycle and moves huge plates on the Earth's surface, causing earthquakes and volcanoes. The landforms we see today result from processes that build up and break down Earth structures. These fundamental ideas will enable students to understand the history of their planet, Earth processes occurring today, and future geologic events.
6-8.ES2F. The crust is composed of huge crustal plates on the scale of continents and oceans which move centimeters per year, pushed by convection in the upper mantle, causing earthquakes, volcanoes, and mountains.
6-8.ES2F.2. Students are expected to describe what may happen when plate boundaries meet (e.g., earthquakes, tsunami, faults, mountain building), with examples from the Pacific Northwest.
6-8.ES2G. Landforms are created by processes that build up structures and processes that break down and carry away material through erosion and weathering.
6-8.ES2G.1. Students are expected to explain how a given landform (e.g., mountain) has been shaped by processes that build up structures (e.g., uplift) and by processes that break down and carry away material (e.g., weathering and erosion).
