ECb Develop and use models to represent their ideas, observations, and explanations through approaches such as drawing, building or modeling with clay. Students will build and construct their own bridges to experiment to see what materials build the strongest structure. ECc Plan and carry out simple investigations. Students will create and test their own bridges and towers to withstand different weights. ECd Investigate and participate in activities using visual arts materials Students are creating three-dimensional works of art while experimenting with form, texture and space with dry spaghetti noodles and straws.
Strong, Sturdy, Structures Use every day and recycled materials to create bridges and towers to support different weight sizes! If you notice any shearing bending or twisting of the structure , support the area with additional triangular support beams. Cut your balsa wood beams with sawing motions rather than with pressure. Pressing a sharp edge into the balsa wood will compress the wood fibers and reduce the overall strength of the beam.
Sawing motions will cut the wood cleanly. If your structure is only slightly over the weight limit, sand your structure to remove some excess weight.
Any joints where glue is visible will be particularly good to sand, as the glue is the heaviest component of your structure. Brian Richards is an attorney whose work has appeared in law and philosophy journals and online in legal blogs and article repositories.

You probably had to go through multiple iterations of building your tower until you found the design that worked best.
This is a normal feature of the engineering design process. This activity brought to you in partnership with Science Buddies. Follow him on Twitter BenFinio. Already a subscriber? Sign in.

Materials Toy cardboard or wooden blocks, or an assortment of empty cardboard boxes—cereal, tissue, shoe boxes, etcetera Do not use plastic snap-together blocks.
Pencil and paper Chair to stand on or an adult to help you put blocks on the top of your tower optional Fan optional Preparation Make sure you have enough open floor space to build a tall tower and that it will not break anything if it falls over.
Gather all your blocks before you start. Count how many blocks you have and sort them roughly by size small, medium and large. Make sketches of a few different block tower designs. Procedure Try building one of your tower designs. If the tower gets higher than you can reach, stand on a chair or ask an adult for help to add more blocks.
Can you finish building the tower before it falls over? If you manage to finish building the tower, try gently tapping it with your finger in a few places.
