MS-PS1-6

SCUSD NGSS Curriculum Guide ====**MS-PS1-6: Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.* ** [Clarification Statement: Emphasis is on the design, controlling the transfer of energy to the environment, and modification of a device using factors such as type and concentration of a substance. Examples of designs could involve chemical reactions such as dissolving ammonium chloride or calcium chloride.] [//Assessment Boundary: Assessment is limited to the criteria of amount, time, and temperature of substance in testing the device.//] ====

Science Background for the Teacher:
If something gives off heat or light, it is exothermic.

Key Vocabulary:

 * [key vocab term for this performance expectation] || [key vocab term for this performance expectation] || [key vocab term for this performance expectation] || [key vocab term for this performance expectation] ||
 * chemical process || thermal energy || exothermic || endothermic ||

Possible Assessments (formative and/or summative):
Provide the students with different substances. Have them make their own decisions on how to increase the temperature of a set amount of water a prescribed amount.

Key Student Activity:
Multiple experiments dissolving different substances into water to notice the temperature released by each substance and different quantities.

Key Teacher Demo/Activity:
Glow stick.

Common Student Misconceptions:
Students think that more of a chemical is always better. The more reactant, the better the reaction.

Things to Avoid/Correct:
Avoid relaxed safety: aprons and goggles will be a must.
