Science Symposium 2009

The sixth annual Science Symposium meant  7th and 8th graders ready to share their work with the school community. As always – an impressive display of investigation, collaborative work and erudition. These students know their work and why it matters.  And they are more than happy to share their research.

In a new departure this year, the 5th and 6th grades were part of the expo. P5082108The 5th grade presented their  “Simple Machines” – Rube Goldberg devices demonstrating kinetic  and potential energy combined with gravitational pull tied together with string and wire.  Marbles, blocks, P5082119cardboard tubes, clothes pegs, dominoes of horror movies and a blue plastic severed hand were all pressed into service.

The sixth grade had their programmed robots on display and on mission, including one accomplished mechanical ballet.
