Construct a time line of the discovery of some elements.

Materials – metric ruler, paper ~35 cm x 11 cm, colored pencils

Procedures:

1.  Plan out your time line. You have about 350 years to put on your piece of paper. Use your ruler

2.  Draw a line on your paper the length that you need. Use your ruler.

3.  Make a scale. Draw small marks with your ruler on your line showing the years.

4.  Label the marks. Write the years on the marks for the scale you have chosen.

5.  Fill in the time line. Write each of the elements from the chart and their dates of discovery in the proper place on your time line.

6.  Show a use. Draw a picture on the time line that shows a use for each element. Use your colored pencils

7.  Make an appropriate title for your time line and write it at the top.

8.  Make an appropriate scale for your time line and write it at the bottom.
