Presentation Transcript

  1. The Periodic Table: Episode 1Members of the Empire • Each lab table has samples of different elements. • Write its state: solid, liquid or gas • Write its color (or lack of color) • Write its luster: shiny or dull • Follow the directions at each table for investigating the physical properties of the elements. • Write the description of the properties in each element’s space on the giant periodic table.

  2. The Periodic Table: Episode 1Members of the Empire • Use a highlighter to draw the stairstep line. Discuss the following with your group: • What are the properties of the elements on the left of the stairstep line? • What type of elements are on the left of the stairstep line? • What are the properties of the elements on the right of the stairstep line? • What type of elements are on the right of the stairstep line? • What are the properties of the elements on the stairstep line? • What type of elements are on the stairstep line? Summarize your findings in the chart on the bottom of page 6.

  4. The stairstep line Metalloids/semi-metals are on it Nonmetals are to right of it Metals are to left of it Color code the PT on page 7. You may pick your own colors. Fill in the legend at the top. Metals Metalloids Nonmetals

  5. Alderaan • There are samples of 4 different elements in the glass tubes. • Describe their appearance inside the tube. • Turn the switch on the right side to see what color each emits when its electrons are excited by electricity. (Do not write that part down.) • Turn the switch off.

  6. Endor • There are samples of 3 different elements in the test tubes. DO NOT OPEN THEM! • Do not invert the test tubes. • Describe their appearance inside the test tube.

  7. Tatooine • There are samples of 3 different elements in the test tubes. DO NOT OPEN THEM! • Do not invert the test tubes. • Describe their appearance inside the test tube.

  8. Naboo • There are samples of 3 different elements in the test tubes. DO NOT OPEN THEM! • Do not invert the test tubes. • Describe their appearance inside the test tube.

  9. Hoth • There are samples of 2 different elements and one insulator. • Describe the visual physical properties of the 2 elements. • Place a piece of ice on each element and on the insulator. Observe the change in the ice on each. • Use your observations to describe each element as an insulator or a conductor of heat. • Place the ice/water in the sink.

  10. Dagobah • There are samples of 5 different elements and a digital multimeter. • Turn on the multimeter by pressing in the power button on the top left. The screen should read “1”. • Have your partner watch the screen as you place the metal tips of both probes on a sample. Be careful not to let the probes touch each other. • If the number changes, the sample conducts electricity. If it stays at 1, the element does not conduct electricity. Record your observations on the giant periodic table. • Turn off the multimeter by pressing the power button.
