How Cool Is Your Environment?
Kenneth Blackman Santa Rosa District Schools
Description
The students calculate heat energy and convert from one temperature scale to another. The students will be able to manipulate formulas need for conversions.
Objectives
The student knows the appropriate operations to solve realworld problems involving integers, ratios, rates, proportions, numbers expressed as percents, decimals, and fractions.
The student solves multistep realworld problems involving fractions, decimals, and integers using appropriate methods of computation, such as mental computation, paper and pencil, and calculator.
The student applies formulas for finding rates, distance, time and angle measures.
The student knows a variety of strategies to estimate, describe, make comparisons, and solve realworld and mathematical problems involving measurements.
Materials
Student worksheet
Pencil
Calculator
Preparations
Duplicate the worksheet in the associated file for the students.
Procedures
1. Discuss with the students how to calculate heat energy.
Heat gained or lost= Mass x Change in temperature x Specific heat
2. Model problems on the board for the students.
3. Discuss with the students how to convert temperature from Celsius to Fahrenheit.
F = 9/5C + 32
4. Model problems on the board for the students.
5. Discuss with the students how to convert from Fahrenheit to Celsius.
C= 5/9(F32)
Assessments
The worksheet should be formatively assessed by the teacher. Students who have difficulty or calculate incorrect answers should receive feedback and additional practice time.
Extensions
The students could compare temperatures from the local newspaper and convert to the celsius scale using the appropriate formula.The students could compare temperatures using a graph.
