The third graders went to two sessions in the Agmobile. The first
one was called The Tree Story. The students were introduced to
dendrology where they dated two tree samples and identified patterns of
tree growth. Various parts of the tree and their purposes were
identified. The second one was called Glue From Milk. The students acted
as chemists and lab techs as they produced glue from milk and then
tested the strength of their glue against Elmer's glue.
