Ever Eat an insect? Well, one group of students recently
did so, almost. Students studying insects and their exoskeletons led me to a
new activity. Make an insect!
The
exoskeleton of an insect is remarkable. It has many layers of cells designed to
shape, protect and grow new layers when molting time comes.
We started
our skeleton with a layer of wax paper to represent the inner membrane. Then
laid down a layer of M&M’s as the epidermis layer (this made it both
crunchy and uniform like the layer should be.
Next came a
slice of bread followed by a slice of toast. These represented the protein
layers of the cuticle. A layer of peanut butter on top of the toast was the fat
layer. A fruit roll up made the waxy layer that keeps an insect from drying out
and finally a cracker on top finished the hard outermost layer. Of course
insects sometimes have spikes and strange surface textures which would be a
feature of this final top layer.
So, did they
learn anything? They sure liked eating our creation. And hopefully they took
home new knowledge that an insect might be more complex than it seems.
