ESSENTIAL QUESTION: Why are physical and chemical properties useful?
BENCHMARKS: SC.8.P.9.2
LEARNING OBJECTIVES: Students will be able to:
-Compare and contrast physical and chemical changes
-Explain that adding heat to or removing heat from a substance may result in a temperature change and possibly a change of state.
-Explain that mass is conserved when substances undergo physical and/or chemical changes according of the Law of Conservation of Mass.
BELL RINGER: Hot and Cold Balloons
VOCABULARY: matter, substance, solid, liquid, gas, fluid, temperature, thermal energy, heat, melting point, freezing, vaporization, evaporation, boiling, point, condensation, particle, Law of Conservation of Mass
HOME LEARNING: HL 6 Law of conservation of Mass
AGENDA
WHOLE GROUP
Students completed the bell ringer Hot and Cold Balloons, by writing their answer on the white board paddles and sharing with their classmates.
Students received HL 6, which can be found above. Students should write on the handout and return. I will make a copy.
Students received the information for the project infograph, which can be found below. We will use part of next class period to work on research for the infograph.
Students watched the BrainPop on Conservation of Mass. Unfortunately, the video is not available for free online. However, you can go to YouTube and watch any video on the Law of Conservation of Mass.
Students took notes on physical and chemical changes of matter and the law of conservation of matter. You can find a movie of the power point below.
Students then did an experiment to determine the conservation of mass. While the experimental portion was completed, students will complete the write up in their lab notebooks next class.
