Product Description

In Too Deep Story: The year is 1869 and work has just begun on the Brooklyn Bridge. The chief engineer is planning to anchor the bridge on an underwater foundation and the digging will take place inside the relative dryness of a pneumatic caisson. (A caisson is essentially a large box filled with compressed air to keep the water out.) As the pressure in the caisson increases, workers begin to fall ill with an unknown disease. Students will learn about and apply gas laws as they help the chief engineer with this difficult feat of engineering.

This product is also part of a BUNDLE found here.

Objectives:

General:

-Describe and calculate the relations between volume, pressure, number of moles, and temperature for an ideal gas as described by Boyle's law, Charles' law, Avogadro's law, Dalton's law of partial pressure, and the ideal gas law.

-Describe the postulates of kinetic molecular theory.

-Perform stoichiometric calculations, including determination of mass and gas volume

relationships between reactants and products and percent yield.

NGSS:

-HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

-HS-PS3-2. Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative position of particles (objects).

-HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.temperature for an ideal gas as described by Boyle's law, Charles' law, Avogadro's law, Dalton's law of partial pressure, and the ideal gas law.
