\checkmark The students will participate in a class-wide discussion of visible signs of stress on an object and its causes, as well as define the "strength" of an object.

\checkmark The students will record the definitions of stress, strength, deflection, and point of failure in their notebooks.

\checkmark The students will view a video clip of a 4-point-bend stress test that was filmed live at a NASA Structures and Materials Research Lab.

\checkmark The students will review the "Lab Safety Rules" for the classroom prior to beginning the 3-point-bend stress test with their lab partners.

\checkmark The students will test the strength of 3 small popsicle sticks and 3 large popsicle sticks by measuring the amount of suspended mass that that causes failure and recording the information in their data table.

\checkmark The students will create a line plot using the class data (compiled by teacher) and analyze the data by responding to a series of prompts.

\checkmark The students will compute material properties of the popsicle sticks and use them to predict future tests.

\checkmark The students will draw conclusions and make predictions based on the data.

\checkmark Using the simulation programs World of Goo and West Point Bridge Builder, the students will learn the basics of bridge design and design a blueprint for a bridge that can withstand a given amount of stress and stay within budget.

\checkmark The students will construct their bridge according to their design.

\checkmark Students will evaluate the overall success of their design and application with bridge building after their bridge is put under a strength test by the teacher.
