Temperature is proportional to heat and is the measure of the average kinetic energy of the molecules in a system. TESS-India (Teacher Education through School-based Support) aims to conceptions that your students might hold in relation to heat and temperature. What sorts of experiences of heat and temperature are children likely to have through. Specific Heat. The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and .
Defining thermal equilibrium The zeroth law of thermodynamics defines thermal equilibrium within an isolated system. The zeroth law says when two objects at thermal equilibrium are in contact, there is no net heat transfer between the objects; therefore, they are the same temperature. Another way to state the zeroth law is to say that if two objects are both separately in thermal equilibrium with a third object, then they are in thermal equilibrium with each other. The zeroth law allows us to measure the temperature of objects.Heat and Temperature
Any time we use a thermometer, we are using the zeroth law of thermodynamics. Let's say we are measuring the temperature of a water bath.
In order to make sure the reading is accurate, we usually want to wait for the temperature reading to stay constant. We are waiting for the thermometer and the water to reach thermal equilibrium! At thermal equilibrium, the temperature of the thermometer bulb and the water bath will be the same, and there should be no net heat transfer from one object to the other assuming no other loss of heat to the surroundings.

Converting between heat and change in temperature How can we measure heat? Here are some things we know about heat so far: When a system absorbs or loses heat, the average kinetic energy of the molecules will change.
Thus, heat transfer results in a change in the system's temperature as long as the system is not undergoing a phase change. Introduction The increase in the population growth rate may affect several problems. The lack of people understanding on scientific insight to make a good decision might cause the social problems and natural disasters such as an unemployment, a colonialist, a poverty, a flooding, a fire, and so on.
As a citizen, we have to concern on how to solve these problems by improving the people-scientific mindset. Moreover, PISA study on scientific literacy showed that Indonesia was positioned at 62th out of 70 countries participating in the survey.
Art viewed that the modernization of social life was closely related to the development of science and technology. This transformation cannot be realized so that the new generations are able to understand the new issues and to decide based on scientifically reasonable evidence.
Therefore, a literate citizen should be able to evaluate the quality of scientific information on his participation in civic and cultural affairs, and economic productivity Miller, To realize this condition, learning activities should not only focus on what students know about science, but also concern on how they use science to decide based on scientific information. Consequently, a good teacher must have an awareness of his duties as an educator.

He must facilitate students finding several ways of developing their own potential because this is the child's right to obtain the best opportunity Eisenkraft, Science is a good particular way to understand the natural phenomena. Students should learn how to use their way of thinking to investigate the factual issues DeBoer, Therefore, Dewey argued that the inquiry-based learning presented a real experience using scientific ways of building knowledge or solving problems.
Compared to other aspects of scientific literacy, an adequate understanding of the nature of science NOS plays the most important role in improving the scientific literacy American Association for the Advancement of Science - AAAS, The scientific literacy refers to the ability of the individual to read, comprehend, and express his opinion on scientific matters are required to become a scientifically literate person Miller, National Research Council initiated scientific literacy including 1 concepts and processes for physics and biology, 2 inquiry scientific methods, 3 science application in daily life, and 4 social and environmental implications and technology development.
Scientific literacy is nowadays a goal of science education Wenning, By considering the large scope of scientific literacy, the assessing direct improvement of scientific literacy is quite complicated to be accomplished. PISA strongly recommend that the most important thing to be trained to the student is by implementing experiments and hands-on activities. This work can help students develop a conceptual understanding of scientific ideas and transferable skills, such as critical thinking.
For instance, scientists are able to formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models.
In areas where active research being pursued, it is normal for a scientist to differ from one another about the interpretation of the theory or evidence. Accordingly, the examination includes reviewing the experimental procedures, examining the evidence, identifying faulty reasoning, pointing out scientific interpretation, and suggesting alternative reasons for the same observations. Interestingly, it was also believed that laws were proven true and theories were tentative, either because not enough data are available or because scientists are unable to design experiments or apparatus to test theories adequately.
It is a challenge to a teacher to design good experiments and to set up apparatus correctly. Teachers must guarantee that the scientific content is meaningful and important to students, not as lifeless abstractions DeBoer, They should conduct this process using inquiry-based or constructivist teaching. Duschl states that teachers themselves need to have an adequate understanding of the nature of science.
To improve the nature of science, PISA suggested that the teachers need to design well-structured laboratory activities that make actual scientific concepts and ideas. It will help students make the connections among the scientific ideas, hands-on activities, and real-life problems.
Students should also be made aware that while conducting these activities, they are manipulating objects as well as ideas. The reason, why a teacher feels difficult serving this equipment, is a lecturer weakness in providing the real scientific experiences to the prospective students Niess, The educational curricula must engage the student to be able to design good science experiments.

The characteristics of learners should be recognized to provide wise ways of building their knowledge so that students are interested and not easily frustrated. For example, a teacher firstly shows a contextual phenomenon related to the expected concept. He composes learning outcomes as a base for developing instrument and learning strategies.
