## How Cool Is Your Environment?

### Kenneth BlackmanSanta 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 real-world problems involving integers, ratios, rates, proportions, numbers expressed as percents, decimals, and fractions.

The student solves multi-step real-world 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 real-world 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(F-32)

#### 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.
