In Science Class . . . Week of 2/27

This week, the students have been studying the structure of the earth and the types of rocks (and how they form). We took some notes, discussed and played a game to reinforce vocabulary. Next week, we'll be moving on to weathering and erosion.
Key questions to ask:

• What are they layers of the earth? (Core, mantle, crust)
• What are the three types of rocks and how are they formed? (Igneous rock is rocked formed from the cooling of the mantle. Sedimentary rock is rock formed when bits of other rock are pressed together. Metamorphic rock is rock formed from heat and pressure.)
• What processes are important in the rock cycle? (Weathering, melting, heat and pressure are important ways that rocks can, over a long time, be changed into a different type of rock.)
