Bridge strength was approximated by attaching a bucket (~2 lbs) and then slowly adding one gallon of water (7 lbs) at a time. The strongest bridge of the day held 21 lbs!

Bridges were also constructed on-site at the conference. Materials provided for construction were simply dry pasta and hot glue.
The bridges shown below were built at home and brought to the conference to be tested for strength.
Builders were quite proud of their creations.
STEC participated in the Va Homeschoolers 2014 Conference and Resource Fair, March 21-22 where we provided lots of sensory experiences with plants, insects, shells, rocks,
magnifiers and microscopes.

STEC also hosted a conference-wide spaghetti bridge
building challenge and presented two lectures:
"Developing and Implementing a Curriculum Web" and
"Sensational Science on a Shoestring"
STEC wrapped up the second day with a slime-making activity for about 40 youth participants.

What a great conference!!
