2.Go around and pour two of their spoons of glue in cup,then let a student go around pouring one spoon of water.

3.Tell students to mix it around and tell then to write descriptive words to describe what the glue and water looks like together in that column.

4.Mix borax.Pass some clear cups of Borax and tell them to write in the column under borax solution what they see.

5.Then, go around putting in three spoons of borax in eatch cup.Tell them to stir, and see what happens. (It takes a while to get the formula just right, so experiment at home first.)When they stir, it becomes strechy and gooey.Tell them to wright what they see and feel in the column under Goo.At the end of the day,give the sudents their goo to take home.
