Does ionization energy increase going up or down a column in the periodic table? Do atoms get smaller or larger from right to left across a row?

In this cooperative activity, students use microscale reaction plates and straws of different lengths to construct three-dimensional bar-type charts of element properties. Let students discover for themselves the existence and direction of periodic trends.
