=Summary=

===Students construct mini submarines in order to explain how density, mass and volume work in a real environment. In order to support their mini submarines, students must make calculation relevant to density, mass, and volume as well as account for variables such as water density. ===

=CCSS Alignment for Grades 6-8=


 * ===**6.RP.3 **: //Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.// Students will use the equation for calculating density to see the proportional change between a floating and sinking submarine in relation to the density of water. ===
 * ===**7.G.6: ** //Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms//. Students will solve for volume of three-dimensional objects using the density equation (volume + mass/density). ===
 * ===**8.G.9 **: //Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.// Students will calculate the volume of differently shaped (cylindrical, spherical, etc.) submarines and determine the changes in density that need to take place for the submarines to sink or float. ===
