We have learned about force and motion by exploring with magnets. We have also conducted experiments with static electricity. Some key words to know are: magnet, iron, metal, negative charge, force field,
poles, static electricity, electromagnet, attract,
repel, positive charge
We are exploring the properties of rocks and minerals. We have discovered that a minerals hardness can be measured and compared to Mohs hardness scale. We have also done a streak test to help us identify minerals. We are learning that rocks have a cycle. Some key words to know are: physical property, matter, characteristics,
strength, hardness, flexibility, conduct, color, luster, cleavage,
igneous, sedimentary, metamorphic, transform, composition, mineral, sediment,
observable, molten, deposit, compacted, streak, classify
