Product Details

A spectacular “fireworks” display is initiated by adding two drops of water to a mixture of dry chemicals. Place a beaker with very small amounts of zinc dust, ammonium nitrate and a catalyst in a fume hood. Add two drops of water to the mixture and watch as sparks, smoke and excitement fill the air. Must be performed on a heat-resistant surface in a fume hood or outdoors.

Concepts: Exothermic reactions, catalysts.
Time Required: 15 minutes

Performance Expectations

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
HS-PS2-2: Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
HS-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
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 motion of particles (objects) and energy associated with the relative position of particles (objects).
HS-PS3-4: Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
