Describing & Classifying Matter Name _____________________________________ Connection to your world: The color of the sunset depends on the __________________ present in the air. As the Sun gets lower in the sky, its light passes through more of the atmosphere to reach you. More of the blue and violet light is absorbed, allowing the reds and yellows to pass straight through to your eyes. Large particles in the atmosphere _______________ more of the reds and yellows, sometimes making the whole western sky glow red. Today’s Objectives: We are going to review the ________________ ___ __________________. Previously we discussed the classification of matter based on the composition of the matter.

We classified matter according to its composition. Now we will describe the sample of matter using the __________________________ _______________________. Which sample can you find on the periodic table? _______________________________ Why is it the only sample you can find on the periodic table? ______________________________________________________________________ The periodic table organizes elements using their _____________________ and _______________________ properties. Does this picture help us find aluminum on the periodic table? __________, the picture uses _____________ physical properties to identify aluminum. The periodic table also uses chemical properties to identify aluminum. What atomic information about aluminum is given to us by the periodic table? ________________________________________________________ Now you try: You have 2 minutes Use the back of your book. Find the element Chlorine on the periodic table. Write the information you find about chlorine. Chemical symbol: ___________ Atomic number: _____________ Atomic mass: _________________________ What information would you use to prioritize elements? __________________________________________________________________________ The periodic table uses what information to prioritize elements? ____________________________________________________________________ Review Objectives: The following are the objectives we discussed today: _________________ types of matter. __________________________ matter according to its composition. _____________________ the sample of matter using the periodic table . Conclusion for Today’s Activity: You have 3 minutes Find helium on the periodic table. Use the periodic table to determine 2 physical and 2 chemical property of helium. Use these properties to classify helium. Justify your classification based on today’s lesson (2-3 sentences). ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ Exit for today: Write and then answer the EOC style question: When you are finished, turn in the entire packet.
