Example Lesson PlanLab Summary

• The purpose of this lab
• Demonstrate Chemical Reaction
• Focus on the Physics
• Everyday Applications
• Use to Perform a Calibration

7
Materials

• 1 ea. Vernier LabQuest
• 2 ea. Stainless Steel Temperature Probes
• 2 ea. 1 L Beakers or Plastic Cups
• 2 ea. Cups to hold 200 mL of ice
• Measuring cup
• 30 mL of table salt
• 150 mL of water
• 200 mL of crushed ice
• Container of distilled water
• Container of crushed ice

Where to Get the Materials
9
Preliminary Questions

• How cold is ice?
• A typical freezer -8 oC, deep freezer -17 oC.
• What are the 4 states of matter?
• Solid, Liquid, Vapor, and Plasma
• Hypothesis - What will happen when salt is added
  to one of the beakers?
• The salt, water and ice solution will get colder
  than 0 oC and still remain liquid

10
Procedure

1. Add 150 mL of distilled water to each beaker.
   Place a temperature probe in each beaker and
   allow to stabilize at room temperature
2. Procure two volunteers
3. Set up and start data collection on the LabQuest
4. After several seconds have the volunteers add the
   ice
5. Allow both probes to level off at 0 oC
6. Add 30 mL of salt to one of the beakers
7. Allow the salt water and ice to level off then
   add another 30 mL of salt to the same beaker

Post Lab Discussion

• How can we use our knowledge of water, ice, salt
  and the latent heat of fusion to perform a single
  point calibration on a thermometer?
• Materials
• Distilled water
• Ice made using distilled water
• Clean salt free ice trays
• A clean salt free container
• A thermometer that measures down to at least 0
  oC
• Dont use a glass thermometer
• Use a probe style

13
Post Example Discussion

1. What was the main goal of the activity?
2. What was the key measurement area and concept(s)?
3. How could this activity be modified to increase
   the measurement science focus (e.g., Real Life
   Applications, Traceability, Uncertainty,
   Calibration)?

Lesson Plan Elements
Lesson Plan Element Description
Summary A brief synopsis of the experiment.
Learning Objectives An objective statement that describes the purpose of the activity.
Education Standards Shows how the experiment correlates to curriculum standards of State and/or National education standards.
Materials and Equipment List all of the materials and equipment you need to perform the activity or experiment (e.g., consumable supplies, chemicals, glassware, etc.).
Background Information to bring the instructor up to speed with the concepts used in the experiments, which could include vocabulary words, theory, history, real life applications, equations, sample calculations, and safety concerns.
Extensions Additional questions or activities that allow the student to explore concepts outside of class or apply what they have learned to a new situation. Connections to related measurement topics can also be included.
Assessment Plan Various methods that can be used to assess if learning objectives have been achieved.
Bibliography A list of references used in the activity, such as books, journals articles, or website sources.
