Science Buddies: Stressed Out? Take a Break With This Project!

For Students 6th - 8th
Is an I-beam as strong as a solid beam of the same size? What if you include weight in the comparison: which beam has the greater strength-to-weight ratio? Would an I-beam be stronger than a solid rectangular beam of the same weight?...

Science Buddies: Fractography: The Way Things Break

For Students 6th - 8th
When something goes wrong, do you like to try to figure out why? Engineers do this all the time. They even have a fancy name for it: failure analysis. Understanding how different materials break is an important part of failure analysis....

Science Buddies: Veggie Snap! Modifying Bending Stresses in a Flexible Rod

For Students 3rd - 5th
Examples of the effect of bending stresses on flexible rods could include a large tree bending over to the ground, or a fishing pole bending till it snaps. Scientists actually study this phenomenon and discover ways to prevent breakage,...
