TEACHER: Students have been learning about the periodic table. This lesson connects math to science by interpreting data in the form of two line graphs. They will need a piece of notebook paper. Please remind them to keep the spaces even on each of the x & y axis.

ATC – September 27, 2011Periodic Table Trends

Be sure to turn in to your science teacher by Thursday (9/29/11)

Students: You have been learning about the periodic table. As you have seen, there are many “wonders” contained within this elegant collection of data. Today, you will be graphing one trend in two different ways. Remember to turn this in to your science teacher by Thursday, 9/29/11 as it is counted as a grade.

Line Graph Construction1. Construct two graphs2. On the X-axis for one graph, list the symbols

of elements (1 -20) in order of atomic number3. On the X-axis for the other graph, list the

symbols of the elements in their order by group (family, column)

4. The unit for the Y-axis for both graphs will be the ionization energy in kJ/mol (you probably want to number by 500’s)

5. Plot the points based on the chemical element and the ionization energy

6. Connect each point with a line
