Engineering

Last week, the children had Chesnee Library class with Mr. Jack.  For the past few months, Mr. Jack has been on a kick building things out of straws, masking tape, and aluminum foil.  This month was no exception.  The children have a blast with these simple materials.

The project was to design a container that would protect an egg when dropped.  The instructions were to use only straws, rubber bands, masking tape, and aluminum foil.  The egg was not to be taped into the sling and must be able to be placed into the sling and removed from the sling, without damaging the container.

The children were to work in groups of two or three.  However, some decided to design their own.

Egee and Princess couldn't figure out how to design their container.  I offered advice of building a few large triangles and work from there.  Little Man began working with C-Man and J-Man, but ended up working on his own.


The room was filled with creativity.  No two containers looked alike.


Finally, it was time to test the containers.  Would they protect the egg?  Mr. Jack decided to go ahead and let them tape the eggs in the sling. But, Egee decided not to tape her egg.  She wanted to see if the container we built would really work.  The others taped their eggs.


Mr. Jack dropped the containers from waist level (3 ft).  All survived this small height.  If they had not used tape, only three would have survived.


Next, Mr. Jack dropped the containers from 6 ft high.  Several eggs cracked from this height.  Egee's and three others survived.  Again, her egg would have been the only survivor, if not for the tape.


Egee was proud of her container.  (Even though Mom helped a bit.)
