In this episode of Things Explained, we discuss how a tiny paper clip sinks in water but a cargo ship weighing 250,000 tons floats. We also explain what density, buoyancy, and a man named Archimedes have to do with this science phenomenon.

Mathematics

MGSE4.MD.2

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

MGSE5.MD.3

Recognize volume as an attribute of solid figures and understand concepts of volume measurement.

MGSE7.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.

MGSE8.G.9

Apply the formulas for the volume of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.

Science

S4P3.b

Construct an argument to support the claim that gravitational force affects the motion of an object.

S8P1.c

Plan and carry out investigations to compare and contrast chemical (i.e., reactivity, combustibility) and physical (i.e., density, melting point, boiling point) properties of matter.

SPS5.b

Plan and carry out investigations to identify the relationships among temperature, pressure, volume, and density of gases in closed systems.
