The Natural World Around You! An Introduction to and Interactive Assessment about Energy Forms, States of Water, and Exploration

Standards SC.3.N.1.1 Raise questions about the natural world, investigate them individually and in teams through free exploration and systematic investigations, and generate appropriate explanations based on those explorations. SC.3.P.9.1 Describe the changes water undergoes when it changes state through heating and cooling by using familiar scientific terms such as melting, freezing, boiling, evaporation, and condensation SC.3.P.10.1 Identify some basic forms of energy such as light, heat, sound, electrical, and mechanical.

Asking Questions and Investigating the Natural World Scientific inquiry is multifaceted. Processes of science vs. “The Scientific Method” (Sometimes the process does not traditionally correspond.) The processes of investigating include: Create questions Construct investigation based off of the questions Collect appropriate data Evaluate the meaning of those data Communicate this evaluation

Scientific Investigations Scientific arguing is part of the scientific investigation. Scientific arguing plays an important role in scientific knowledge. Observation: Scientific knowledge is based on observation and inference What does an inference mean? It is an idea or conclusion that’s made based on evidence and reasoning. Questions and explanations are necessary for scientific investigations!

What Are Things Made Of? Everything is made of some kind of “stuff,” “stuff” that you can feel. The term, matter, describes anything that has mass and takes up space. Matter can undergo a variety of changes. Matter can be physically or chemically changed. July 22, 2012 Footer text here

States of Water Melting: Solid  Liquid; The temperature at which a given material, or water, changes from a solid to a liquid; 32 degrees Fahrenheit or zero degrees Celsius Freezing: Liquid  Solid; The solidification phase where a liquid turns into a solid when its temperature is lowered below its freezing point

States of Water Boiling: Liquid  Gas; The temperature at which a given material, or water, changes from a liquid to a gas; boiling point is the same temperature as the condensation point Evaporation: Liquid  Gas; The process of a liquid changing into a gas; when water turns into steam is an example Condensation: Gas  Liquid; The process of a substance, or water, in a gaseous state, transforming into a liquid state.

Energy Energy: The ability to do work and cause a change in matter. Energy is involved in all physical processes and is a unifying concept in many areas of science. Energy exists in many forms and has the ability to do work or cause a change.

Forms of Energy Light: A type of energy with the ability to form types of light people can see as well as invisible waves. Heat: A type of energy which transfers particles in a substance, the particles bounce into each other. Sound: A type of energy that is produced when an object is made to vibrate. This energy travels out as waves in all directions. July 2, 2012

Forms of Energy Electrical: A type of energy produced by electrons moving through a substance Mechanical: A type of energy that is moving, it is the form that we most see around us. All moving objects produce this energy.
