    Energy and Chemical Change

    Energy and Chemical Change

    Overview

    This lab is designed to help students understand the nanoscale effect of various energy inputs on the crystal lattice of a smart material, Nitinol. 

    Standards

    HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles 

    HS-PS2-6. Communicate scientific and technical information about why the molecular level structure is important in the functioning of designed materials. 

    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. 

    Learning Objectives

    The students will use the heat equation,  q=m c T  for calorimetry problems.

    Materials

    Nitinol wire

    Procedure

     

    3min 

    Get started/Drill/Do Now: (What meaningful activity will students complete as soon as they enter the classroom?) 

    BW-Vocabulary-Alloy, Heat capacity, phase change, temperature, heat 

     

    5 pts 

    4min 

    Engage/Motivation: (How will student interest be sparked?  Is there prior knowledge that should be tapped?  Is there vocabulary that must be cleared?  Is there brainstorming that student need to complete before the lesson begins?) 

    Demonstration Warmup- 

    Demonstrate how Nitinol behaves differently from other alloys 

     

     5min 

    Whole Group Instruction: (Focus lessons [explicit teaching/modeling, strategy demonstration, activate prior knowledge], shared reading, shared writing, discussion, writing process.)

    20 min 

    Group Practice/Small Group Instruction: (teacher-facilitated group discussion, student or teacher-led collaboration, student conferencing, re-teaching or intervention, writing process) 

    Student Lab: Number Nanotechnology Invention and Design: Phase Changes, Energy and Crystal- (Resource Google drive-Nano 2016-Lesson 4, File Name: Phase Changes SW modifies) 

     

    10 min 

    Independent Practice: (individual practice, discussion, writing process.)  

    Student Lab: Number Nanotechnology Invention and Design: Phase Changes, Energy and Crystal- Post Lab Questions 

     

     

    5 min 

    Evaluate Understanding/Assessment: (How will I know if students have achieved today’s objective?)  

    Whole class discussion of Results and post lab questions. Collect assignment next day. 

     

    30 pts 

    5 min 

    Closing Activities/Summary: (How will I tie up loose ends, reinforce/revisit the objective and connect the lesson to the unit?)  

    Exit Quiz-Career search 

     

    5 pts 

     

    Enrichment/Extension/Re-teaching/Accommodations: (How will my lesson satisfy the needs of all learners?)
