Content Standard G: History and Nature of Science

Nature of Science

Scientists formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Although all scientific ideas are tentative and subject to change and improvement in principle, for most major ideas in science, there is much experimental and observational confirmation. Those ideas are not likely to change greatly in the future. Scientists do and have changed their ideas about nature when they encounter new experimental evidence that does not match their existing explanations.

Transfer of Energy

Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical. Energy is transferred in many ways.

Units of Study: Heat and Changes of Matter; Machines and Motion

A. Property of Objects and Materials

2. Heat can be produced in many ways, such as burning and rubbing or mixing one substance with another. Heat can move from one object to another by conduction.

IX. Motions and Forces

A. The motion of an object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph.

Standard 4

The Physical Setting

4. Energy exists in many forms, and when these forms change energy is conserved.

PERFORMANCE INDICATOR 4.2
observe and describe heating and cooling events

Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.

Content Standard A: Science as Inquiry

Understandings About Scientific Inquiry

Different kinds of questions suggest different kinds of scientific investigations. Some investigations involve observing and describing objects, organisms, or events; some involve collecting specimens; some involve experiments; some involve seeking more information; some involve discovery of new objects and phenomena; and some involve making models.

Content Standard A: Science as Inquiry

Understandings About Scientific Inquiry

Scientific investigations sometimes result in new ideas and phenomena for study, generate new methods or procedures for an investigation, or develop new technologies to improve the collection of data. All of these results can lead to new investigations.

Light, Heat, Electricity, and Magnetism

Electricity in circuits can produce light, heat, sound, and magnetic effects. Electrical circuits require a complete loop through which an electrical current can pass.

Transfer of Energy

In most chemical and nuclear reactions, energy is transferred into or out of a system. Heat, light, mechanical motion, or electricity might all be involved in such transfers.

Properties of Earth Materials

Understand that objects are made of more than one substance, by observing, describing and measuring the properties of earth materials, including properties of size, weight, shape, color, temperature, and the ability to react with other substances

IX. Position and Motion of Objects

C. The position and motion of objects can be changed by pushing or pulling. The size of the change is related to the strength of the push or pull.

Properties and Changes of Properties in Matter

Substances react chemically in characteristic ways with other substances to form new substances (compounds) with different characteristic properties. In chemical reactions, the total mass is conserved. Substances often are placed in categories or groups if they react in similar ways; metals is an example of such a group.
