HT7.2
Explain how understanding differences between states of matter and the effect of heat on changes in state provide evidence for the particle theory.

SI

Indicators for this outcome
(a)

Provide examples from daily life that illustrate the effects of heating and cooling on solids, liquids, and gases.

(b)

Conduct experiments to determine the effects of changes in temperature on solids, liquids, and gases.

(c)

Construct and label a heating curve for water, using student-collected data, indicating states of matter and changes of state.

(d)

Create a visual or dramatic representation to explain changes of state of matter (e.g., melting, freezing, evaporation, condensation, and sublimation) according to the particle model of matter.

(e)

Choose appropriate instruments (e.g. alcohol thermometer, temperature probe, and thermocouple) and use them safely, effectively, and accurately for collecting temperature data when investigating states of matter and changes of state.

(f)

Trace the historical development of different scales (e.g., Kelvin, Celsius, Fahrenheit, and Rankine) and instruments used to measure temperature (e.g., liquid-in-glass thermometers, bi-metallic strips, digital thermometers, liquid crystal thermometers, thermocouples, and computer sensors) and discuss the need for standardized measurements of temperature.

(g)

Distinguish between heat and temperature using the concept of kinetic energy and the particle model of matter.

(h)

Explain how evidence gathered while investigating states of matter and changes in states of matter supports or refutes the particle theory of matter.

Pearson Saskatchewan Science 7. Student Text
Saskatchewan Science 7 is custom published for Saskatchewan and developed by a team of Saskatchewan teachers. Each unit starts with a list of Big Ideas that sets the focus for the unit. A Big Idea then provides the title for each section in the unit. Throughout the unit, opportunities are provided for students to work together, communicate ideas, perform experiments and carry out library and Internet research. Key vocabulary is bolded throughout the unit and an explanation of each term is provided. All key terms and explanations are also listed in a glossary at the back of the text. First Nations and Métis content, perspectives and ways of knowing are an integral part of the Saskatchewan science text. Highlights of the activities and achievements of Saskatchewan men and women are provided in the "Ask ..." feature. In each unit, the "Ask ..." feature provides access to the wisdom of a First Nations or Métis Elder or Traditional Knowledge Keeper, who shares an oral story related to the content of that unit.
