|Essential Question: |How are temperature and heat related? |
| |How does the particle motion of a substance relate to temperature and the state of the substance? |
|Student WILL KNOW |Kinetic molecular theory of gases |
| |A gas consists of a collection of small particles traveling in straight-line motion and obeying Newton’s Laws. |
| |The molecules in a gas occupy no volume (that is, they are points). |
| |Collisions between molecules are perfectly elastic (that is, no energy is gained or lost during the collision). |
| |There are no attractive or repulsive forces between the molecules. |
| | |
| |States of matter reflects the amount of motion of the particles; gases exhibit the most particle motion and solids|
| |the least. |
| |The difference between heat and temperature |
| |The difference between heat and thermal energy |
|Student WILL UNDERSTAND |The amount of motion of particles in a system determines the temperature of a system. |
| |When heat is added to a substance, the particles of that substance acquire more energy and may change phase if |
| |enough heat is transferred into or out of the substance. |
| |The change of phase of a substance may be graphed and calculations may be made from this information. |
| |Using the specific heat, mass and change in temperature of a substance the change in energy can be calculated. |
|Student WILL be able to DO (skill) |Use a thermometer to measure temperature |
| |Convert from one temperature scale to another |
| |Calculate the heat of a material using the specific heat. |
| |Interpret a phase change diagram. |
| |Conduct an experiment to determine the specific heat of a material |
| |Conduct an experiment to determine the melting/boiling point of a material |

SCIENCE LESSON PLAN for TEMPERATURE AND HEAT UNIT
|Lesson Plan Title: |Lesson 1- Introduction to Temperature |
|Grade Level/Subject: |Physical Science 11-12 |
|Essential Question: |How do we measure temperature? |
| |Why do we measure temperature? |
|Engage: |Have several different thermometers sitting on a table at the front of the room. A Galileo thermometer by itself will |
| |be enough to engage the students’ interest. The following website explains how it works How Stuff Works |
| |Ask student volunteers to read the thermometer readings, including the scales, and record the results on the board. Ask|
| |students to compare and contrast the designs of the thermometers |
|Explore: |This is an inquiry activity, so a lab procedure is not included. |
| | |
| |Give the student a plastic water bottle and a clear plastic straw. Ask the student to design the process for turning the|
| |objects into a working thermometer. |
| | |
| |*** The students will write the procedure and list other materials needed to fulfill the task. The teacher will approve |
| |each procedure and provide the needed materials or make suggestions for substitutions that are available. |
| | |
| |The student must find a way to keep the straw upright and straight in the bottle. Provide clay or tape when they ask |
| |for help with this problem. |
| | |
| |Thermometer will respond better with a mixture of water and rubbing alcohol, but the student may not be aware of |
| |this. If several days can be devoted to this activity, then the student may be permitted to discover that water may not|
| |be the best material for this activity. If the time is not available, the student may be given the mixture of water and|
| |alcohol with the straw and bottle. |
| | |
| |After the student builds the thermometer, ask them to attempt to make the device quantitative. ** The students should |
| |begin by exposing the thermometer to different situations. If any of them wish to try lowering the temperature of the |
| |solution to the freezing point, make sure that they understand this will not be 0oC. Discourage the students from |
| |trying to boil the mixture over a Bunsen burner as this may cause the alcohol vapor contained in the mixture to ignite. |
| | |
| |The following websites can be followed if an inquiry exercise is not desired: |
| |How to Make a Thermometer |
| |How to Make a Thermometer 2 |
|Explain: |Students should prepare a written report that contains the procedure for preparing the thermometer, the results of all |
| |trials, even if they did not work, and a description of how the thermometer responds to different environments. |
|Elaborate: |Give the students a laboratory thermometer. Ask them to compare and contrast the thermometer that they made to the |
| |laboratory thermometer. They may record their answers and/or sketch and label a diagram. |
|Evaluate: |Lab report including the comparison to the laboratory thermometer |

|Connections to Other Disciplines: |Writing skills will be emphasized in the preparation of the lab report. Measuring skills are also important in this |
| |lab. Therefore, this lab is connected to both English and mathematics skills. The inclusion of the Galilean |
| |thermometer would also be a connection to history and technology depending on how the thermometer is presented and |
| |developed. |
|Materials: |straws |
| |plastic water bottles |

|Essential Question: |How do temperature scales differ? How can you convert from one temperature scale to another? |
|Engage: |How could we have made the thermometers that you made more accurate? |
| | |
| |The students should answer that they would mark all of the straws in the same way, and all of them would use the same |
| |amount of the water/alcohol mixture. |
|Explore: |Changing Temperature Scales Lab (see below) |
| |This lab was written for the NOVA 5000. Any temperature probe device could be used to perform the activity and the |

Temperature Conversion Worksheet
The two temperature scales used most often to record temperature are the Celsius scale and the Fahrenheit scale. The Fahrenheit scale is used almost exclusively in the United States while the rest of the world used the Celsius scale.
To Convert from one scale to another the following formula may be used:
oF = 1.8 oC + 32 (What does the 32 represent?)
In other classes you may have used the fraction 9/5 instead of the decimal 1.8 to find the Fahrenheit or Celsius temperature values. Replacing the fraction with the decimal will make the algebra needed to solve for either temperature easier to work using a calculator, AND if the decimal value is rounded to 2 estimation of the temperature value is much easier.
Convert 10.0 oC to oF Estimated answer 2x10 = 20 + 32 = 52oF
oF = 1.8 oC + 32
oF = 1.8 (10.0) + 32
oF = 18.0 + 32
oF = 50.0
Convert 10.0 oF to oC Estimated answer 10 – 32 = --22 / 2 = 11 oC
oF = 1.8 oC + 32
10.0 = 1.8 oC + 32
--22 = 1.8 oC
--12.2 = oC
Work the following temperature conversions.
|Celsius oC |Fahrenheit oF |

| |40.0 |
|55.0 | |
| |110. |
|37.5 | |

Discussion Questions: Based on the table above, answer the following:
1) At what temperature (in degrees Celsius) would it have to be outside before you wore a winter coat? Why?
2) At what temperature (in degrees Celsius) would you want it to be outside before you went swimming? Why?
3) If it is 20 degrees Celsius outside, how would you describe the temperature - Hot, warm, cool, or cold? Why?
The International System of Measurements (SI) uses the Kelvin scale for measuring temperature. The Kelvin scale is based on the concept of absolute zero, the theoretical temperature at which molecules would have zero kinetic energy. Absolute zero, which is about -273.15 oC, is set at zero on the Kelvin scale. This means that there is no temperature lower than zero Kelvin, so there are no negative numbers on the Kelvin scale.
The equation used to convert measured temperatures from a Celsius thermometer to the Kelvin scale is:
K = oC + 273.15 To make the equation easier to remember, the added value is
usually rounded to 273

|Explore: |Energy Needed to Melt Ice |
| |As a safety factor have the hot water prepared ahead of time. This lab was written originally for a first year chemistry|
| |lab that would frequently use Bunsen burners to prepare hot water. By preparing the hot water for the students, the |
| |risk of a burn injury may be avoided. |
|Explain: |Students will analyze the data they collect during the lab activity to answer the questions in lab report. |
|Elaborate: |Students research the use of water to prevent frost damage to crops |
|Evaluate: |Have students enter their heat values into a spreadsheet on a central computer so the average class value can be |
| |calculated. The students may then compare their percent error to the class value percent error. They should then |
| |explain the difference between their results and that of the average value of the class in the analysis section of their|

Energy Needed to Melt Ice
Purpose
Students will determine the energy needed to melt one gram of ice by measuring the heat lost by a known quantity of warm water when the ice is added to the water and allowed to melt.
Safety
1. Wear goggles at all times when in the laboratory.
2. A Bunsen burner or hot plate is used in this lab to warm the water to about 50 o C.
Beakers do NOT look hot when they are heated so use hot pads to handle them.
Materials
Two beakers
Laboratory thermometer
Ice
Paper towels
100 ml graduated cylinder
Bunsen burner or hotplate
Procedure
1. Warm water to about 50 o C. Pour about 100. ml into a graduated cylinder and record the volume.
2. Pour the water into a Styrofoam® cup. Measure and record the temperature.
3. Obtain several ice cubes and pat them dry with a paper towel. Place the ice cubes in the cup of warm water.
4. Cover the cup with a lid and insert the thermometer into the hole. Carefully shake the container until the thermometer reads 0.0 o C. Do not stir with the thermometer. If all of the ice melts before the temperature is reached, add more ice. There should be some ice left in the container when the desired temperature is reached.
5. Pour the liquid water into a beaker. Hold back any of the ice that remains and discard the ice in the sink.
6. Pour the water from the beaker into the graduated cylinder to measure the volume. There will be more than 100. ml of water; so the volumes will need to added to find the total volume. Record the total volume of water in the data table.
7. REPEAT THE ENTIRE PROCEDURE AGAIN.
8. Put all of your materials away and clean your station
9. Wash your hands.
10. Return your goggles to the case.
11. Remember that the density of water is 1.00 g/ ml; therefore, one gram of water is equal to one ml of water.
Data Table return to top of lesson
| |Trial 1 |Trial 2 |
|Volume of water (ml) | | |
|Temperature of warm water (o C) | | |
|Equilibrium temperature of ice/water system (o C) | | |
|Final volume of water (ml) | | |
|Mass of ice melted (g) | | |
|Change in temperature of water (o C) | | |
Data Analysis
1. Determine the mass of ice melted for each trial and record in the data table.
2. Determine the change in temperature of the water system and record in the data table. Final temperature – initial temperature = change in temperature
3. Energy = change in temperature x mass of ice x specific heat of ice Use this formula to calculate the amount of energy needed to melt the ice. The specific heat of water is 1.00 calories/ gram · o C or 4.184 joules/ gram · o C. The unit for energy is either calorie or joule, but joule is used more often. The term calorie is deceptive and does not mean the same thing as the calorie used in say a health class when talking about food. Show both calculations.
Trial 1
calories joules
Trial 2

4. Determine the amount of energy needed per gram of ice. Divide the total energy
value calculated in number three by the mass of ice melted.

|Lesson Plan Title: |Lesson 5- Heating and Cooling Curves |
|Grade Level/Subject: |Physical Science 11-12 |
|Essential Question: |How can the melting/freezing point or boiling/condensing point of a substance be found using graphical analysis? |
|Engage: |Heating curves |
| |Display the above website for the entire class using a projector or have the students individually access the site in a |
| |computer lab. |
| |Ask the students to write a paragraph describing what they would see if the water sample that is graphed is in a cup in |
| |front of them. The top of each division displays the particle motion contained within the sample at that particular |
| |temperature. The student papers should begin with the description of ice and progress to steam escaping from the |
| |container. Several rubrics for grading the papers are included. The papers could be written individually or as a group. |
| |paragraph rubric |
| |descriptive paragraph rubric |
|Explore: |The site explains heating curves and has the students perform a virtual experiment to find the melting point and the |
| |boiling point of three different substances. This activity does not include a data table, but it would be excellent |
| |practice to have the students open another screen and construct one. An example format is included in the discussion |
| |area. |
|Explain: |Students will probably assume that the first substance is water; after all the melting point is 0 o C and the boiling |
| |point is 100 o C. |
| |Have them search the internet to find the identities of the other two substances. |
|Elaborate: |Heating Curve worksheet |
| |Download the above worksheet and make enough copies for each of your students |
|Evaluate: |Students, given a piece of graph paper, should be able to construct a cooling curve for water. |
| | |
|Connections to Other Disciplines: |Mathematics Students must know that the slope of a horizontal line is equal to zero and that the slope of a vertical |
| |line is undefined. They must also recall how to find the slope of any other line on a graph and how to identify if the |
| |slope is positive or negative. |

|Lesson Plan Title: |Lesson 7- Determining Experimentally the Melting Point of Ice |
|Grade Level/Subject: |Physical Science 11-12 |
|Essential Question: |If ice is actually melted and temperature data versus time is gathered, will the graph resemble the heating curves from |
| |the previous lesson? |
|Engage: |Have students trace the shape of a typical heating curve on the sheet of paper. Ask them to label the axis-- where are |
| |the temperature and time values placed? |
|Explore: |Melting Point of Ice lab- |
| |This lab activity can be performed using a lab thermometer and a stop watch. The probe measurements will generate more |
| |data points than the students can and make a good comparison, but the student will be able to generate a data table |
| |without the data from the probe. Students should be able to locate the melting point and may even have thought that |
| |their equipment was "broken" when the temperature did not change during the activity. If you have not discussed ideal |
| |conditions for measuring melting and boiling points and the effect of pressure in the process, now would be a good time |
| |to give students this information. |
|Explain: |Compare the graph generated by the probe device and compare it to the one drawn by the student during the |
| |Introduction/Engagement Activity of this lesson. |
|Elaborate: |Explain difference between accepted values and the values found in the data from lab. |
|Evaluate: |After completing the Melting Point of Ice lab, students will complete the following POST-LAB QUESTIONS: |
| | |
| |After printing the graph from the temperature probe and graphing the thermometer data, compare your results. Do you see|
| |the same things? |
| |Label the melting point, boiling point, and any phase changes on both graphs. |
| |Discuss the differences in temperature. Which of these graphs do you feel is more accurate? Why? |
| |Why are the melting point and boiling point not the same as pure water? Explain. |

|Lesson Plan Title: |Lesson 8: Specific Heat |
|Grade Level/Subject: |Physical Science 11-12 |
|Essential Question: |How is heat calculated? |
| |What is specific heat? |
|Engage: |Ask students to list all of the ways that they have measured temperature in the past few days. Include temperature |
| |measurements outside of the classroom as well.Finally, ask them if they have measured or calculated heat. |
|Explore: |Specific Heat of a Metal- Step by step procedures, as well as an place for data collections and calculations are |
| |provided for this lab |
|Explain: |Determining an Unknown- Use specific heat formula to determine the specific heat value of metal that was used in the |
| |experiment. Use this value to identify the metal. |
|Elaborate: |The following paragraph was found on an internet site written about water. The students used water in their lab because|
| |it absorbs heat, but many do not understand the usage. Give them the paragraph to read and let them choose one of the |
| |questions to research. This could be an individual or group activity. The answers should be presented to the class. |
| |Water has a high specific heat index. This means that water can absorb a lot of heat before it begins to get hot. This |
| |is why water is valuable to industries and in your car’s radiator as a coolant. The high specific heat index of water |
| |also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is |
| |gradual rather than sudden, especially near the oceans. |
| |What industry uses water as a coolant? |
| |Don’t they use antifreeze in cars’ radiators, not water? Why? |
| |How could the specific heat of water regulate the seasonal change? |
| |Does the lack of water explain why it is so hot in the desert during the day and so cold at night? |
|Evaluate: |Students will complete the written part of the lab report. Answers to questions on the lab report will be discussed |
| |following the activity. |

Heat Transfer PowerPoint Challenge
One of the content standards that you must master this year is the following:
SC.O.PS. 18 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 (second law of thermodynamics).
Because we are currently studying heat and temperature, your group will prepare a PowerPoint presentation that will concentrate on the heat transfer aspect of this standard. The best
PowerPoint presentation will be given to other science teachers to use in their physical science classes.
Your group must use the internet to find the answers to the following questions.
1. How does the sun produce thermal energy?
2. How is that thermal energy transferred to the surface of the sun?
3. How is the thermal energy emitted from the surface of the sun?
4. How is the thermal energy transferred to the Earth?
Record all of the URLs used for your research by pasting the URL into a word document. Check to see that the link works for these URLs and place a short explanation by each URL. Consolidate all of your group’s findings into the final slide of the power point that you produce.
Finally, prepare a PowerPoint presentation of no more than 10 slides to display the answers to each of the above questions. The PowerPoint should have a title page listing the names of the group members and a final page of URLs. Please print your PowerPoint as a handout in black and white with six slides on a page.

|Lesson Plan Title: |Lesson 12- Performance Assessment |
|Grade Level/Subject: |Physical Science 11-12 |
|Essential Question: |How are temperature and heat related? |
| |How does the particle motion of a substance relate to temperature and the state of the substance? |
|Engage: |This scenario lays the groundwork for the student investigation that follows. |
| | |
| |Ah, you see, there is this business man who likes a large amount of cream in his coffee, and he wants the resultant |
| |mixture as hot as possible. (Alas, there is no microwave oven available). |
| | He has just prepared his boiling coffee when he is called by the boss for a quick conference of ten minutes’ |
| |duration. The boss tolerates no coffee in his presence. |
| | What to do? To keep the coffee as hot as possible should he add the cream now or wait until after the conference? |
| | Which do you think he should do? |
|Explore: |Student develops a working hypothesis and experiment to collect data to answer the question of when to add the cream. |
| |The experiment must be approved by the teacher before the student proceeds. |
|Explain: |Students will create a lab report that contains the question, hypothesis, procedures, data, conclusion, and proper |
| |vocabulary for their research. |
|Elaborate: |Students will be prepared to defend their procedures and conclusions as the results of the experiments are discussed. |
|Evaluate: |The students will use the Rubric for Coffee and Cream as a guide as they create their lab report. They will consider |
| |and question the procedures and conclusions of other lab groups during the class discussion that follows. |
