Vocabulary! I use power points to open my lesson each day. Students then become familiar with the words and are able to read them easily on the tests. This power point includes 18 slides. Words included are water vapor, mixture, dissolve, particle, oxygen, evaporation, evaporate, condensation, condense, precipitation, freeze, melt, contract, expand, microscope, magnify, magnification, and instrument. You can add your own or delete as needed. What a great way to get students ready for a lesson on the water cycle!
