19. 8 th Grade Science Today we will… 8.5 (C) interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements; Objectives: 1.Students will identify and describe the physical properties: luster, malleability, magnetic, conductivity, and density. 2.They will be able to identify the different families on the periodic table and that the elements in the family share physical properties. Wed./Thurs, January 23 &25, 2013

20. 8 th Grade Science Physical Properties Lab 1.Go to 4 stations and observe the physical properties: luster, malleability, magnetic, and conductivity of 5 different elements. 2.Record observations in data table. 3.Answer questions at each station. Wed./Thurs, January 23 &25, 2013

21. 8 th Grade Science Definitions Luster – the way an object or substance reflects light. Ex: glitters, sparkles, glossy, glassy, waxy, dull, metallic. Conductivity – The ability to transfer heat or electricity through direct contact. Malleability – The ability to be hammered into a thin sheet. Ex: silver is very malleable which makes it a good material for jewelry making Wed./Thurs, January 23 &25, 2013

22. 8 th Grade Science Calculating the density With your table, calculate the density of each element. Remember: Density= Wed./Thurs, January 23 &25, 2013 Mass Volume

23. 8 th Grade Science Calculating the density 1.Using the triple-beam balance, measure the mass of each sample. 2.Record the mass. 3.To measure the volume, fill up the graduated cylinder with 20 mL of water. 4.CAREFULLY, drop the element in the water. 5.Subtract 20 mL from the new number on the graduated cylinder. 6.Record this number as the volume. Wed./Thurs, January 23 &25, 2013

24. 8 th Grade Science Calculating the density 1.Using your calculator, calculate the density of the element. 2.Record the density. Wed./Thurs, January 23 &25, 2013
