Airplanes, Bridges and Egg Drops

During second semester we studied physical science. The kids built paper airplanes--learned about Bernoulli's law and some concepts of aerodynamics--and then had fun competing against each other as to who's airplane went the furthest.Using only a manila folder, playdoh, 5o straws and 100 rubber bands, they created-- with out any adult help, ideas or involvement (and this was quite hard for the parents in the younger kids classes) a bridge.
We studied what some elements of a good bridge are and then they went to town.
They were competing against each other as to who's bridge could hold the most weight.

This was a very challenging task for the younger group....although I'm told that the last time they did this the kids in the 5 year old class beat the 10 and 11 year old!

Another competition, this time, an egg drop. Using only rubber bands and Popsicle sticks, and napkins, the kids had to create a crate to house a raw egg that wouldn't break when dropped from at least 5-6 feet above ground.

Connor created a parachute with a napkin for his.

The airplane competition is underway....

Connor's bridge withheld the two block of wood test!

Here's Cailin and Noah's bridge...sadly it didn't and fell under pressure.

The first level of the egg drop challenge....

Eweee, it didn't make it! All three kids passed the first drop. From there Kim, the director, went up the ladder behind her for the second round, which didn't fare well for them. All eggs broke except one--Congrats to Greta!
