What makes arches and triangles so strong? Students will learn about both the physical science and history of arch and truss bridges. Students will perform several experiments to investigate the inherent strength of these shapes and understand why civil engineers frequently use them in the design and construction of structures in general and bridges in particular. Student assessment accompanies the program.
In Working with Scale, students explore the concepts of scale and proportion, along with the relationship between ratios, fractions and decimals. They will learn the various scales used in model railroading and understand that any object can be scaled either up or down. Students will create three-dimensional robots using a few different scales.
How are we alike and/or different from people who lived in the past? This program features our unique collection of historic California model railroads to engage students in an exploration of the past, and an understanding of how some things change while others stay the same. Students identify community elements on model railroad layouts and compare and contrast them to their contemporary equivalents. Finally, students build a 3D model or their community.
