One-Way ANOVA versus Two-Way ANOVA

Class, a One Way Anova and T test both have 1 independent variable and one dependent variable. The independent variable would have 2 groups (ie gender) for the t test and 2+groups (ie.education level) for a One Way Anova. A Two Way Anova has 2 independent variables (each with 2+groups) and 1 dependent variable. The dependent variable in all cases would be interval data.

Can anyone provide a clear everyday example of a 1 way Anova and then compare it with a 2 way anova?
