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!

Spaghetti Bridge Challenge - Constructing Bridges on-site
Bridges were also constructed on-site at the conference. Materials provided for construction were simply dry pasta and hot glue.
Spaghetti Bridge Building Challenge: Home-Built Bridges
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.
Organization of Va Homeschoolers Conference March 21-22
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.
See additional posts for photos of each event.
What a great conference!!
