Physical Properties

One can use their five senses to determine the If the substance has been changes into another substance, a chemical change C has occurred. Physical Change Change in which the identity of the substance does NOT change Chemical Property Characteristic of matter that can only be observed when one substance changes into a difference substance, such as iron into rust Chemical Change Transforms one type of matter into another kind, which may have different properties. To begin, check that Reactant 1 is Sodium and Reactant 2 is Water. Worksheet Answers: Physical and Chemical Changes. Answer key is available on our site for teachers. Give examples. In the Chemical Changes Gizmo, you will look for evidence of chemical changes by looking at changes you can see, touch, or smell.

Properties of matter can be classified as either extensive or intensive and as either physical or chemical. All properties of matter are either extensive or intensive and either physical or chemical. Extensive properties, such as mass and volume, depend on the amount of matter that is being measured. Intensive properties, such as density and color, do not depend on the amount of matter. Solid, liquids, and gases : Water can exist in several states, including ice solid , water liquid , and water vapor gas. Physical properties are properties that can be measured or observed without changing the chemical nature of the substance.

Activity Summary Students visit stations in the classroom to investigate physical and chemical changes and then apply what they have learned to a story about physical and chemical changes that occur in everyday life. Background When Percy Julian entered DePauw University he barely had a 10 th -grade education because public schools for black children stopped at eighth grade across most of the South Julian completed an additional two years at a local teacher training school for Negroes. In addition to his university coursework, Julian took remedial classes at a local high school for two years to catch up with his white classmates. With the help and encouragement of his chemistry professor, Julian succeeded in not only catching up, but in surpassing his peers. He would go on to graduate from DePauw first in his class. In this activity, students do their own investigations into some basic principles of chemistry—they explore physical and chemical change and learn to differentiate between the two.

Each slide is embedded with text to speech audio, making differentiation a snap. Physical or Chemical properties describe matter. Name five additional state of matter from this webpage.

Change is happening all around us all of the time. Just as chemists have classified elements and compounds, they have also classified types of changes. Changes are classified as either physical or chemical changes. Chemists learn a lot about the nature of matter by studying the changes that matter can undergo. Chemists make a distinction between two different types of changes that they study—physical changes and chemical changes. Physical changes are changes in which no bonds are broken or formed.

This activity involves the students in an inquiry based examination of the physical and chemical properties of polymers. Note: This exercise should be changed to make use of the resources available. If a fume hood is not available then delete that portion of the procedures that requires that equipment. Polymers are all around us. Polymers are versatile as you note from the various uses in the materials around and on you, and resource efficient, as polymers consume only 4 percent of the world's oil supply.
