  2. Aim: To observe a variety of igneous, sedimentary and metamorphic rocks • Hypothesis: • Independent variable: • Dependent variable: • Constant: • Materials: • Rock Kit • Hand Lens • Knife/spatula • Dilute HCl

  3. Method: • Test Hardness with a table knife/spatula • Use hand lens to observe grain size & texture • Use a small drop of HCl to see if bubbles are produced – follow teacher’s instructions • Results • Create a table to record: • General appearance • Colour • Hardness • Grain Size • Texture • Reaction with HCl • Classification
