I went on this site that is a project  of the Verizon foundation. At first I was not finding much but than I  learned the Smithsonian Institute  has posted exhibits on the site as lesson plans.  I visited a lesson, All the President's Children and found it very interesting. One had to match the children's faces to the descriptions of the children of the presidents . I also enjoyed reading the letters that children wrote to the Presidents

Julia Child's Kitchen at the Smithsonian  is on this site. Julia Child  actually talks about donating her kitchen to the museum . You can learn all about her life and food.  Children would enjoy looking at the kitchen.

This site contains historical gems. I love this kind of information. I even saw Abraham Lincoln's top hat.

I was impressed with the site and  would never think that the Smithsonian Institution's exhibits would be found  on this site.

Children would find this site 's lessons very interesting. I think they would see that history can be engaging.  The Smithsonian information is  buried on the site and  I am glad I found it.
History classes would find this site useful.
