Quick Question: Use the data from yesterday’s lab to answer these questions. Happened during the lab that you thought was surprising? Why? Describe how the heat changed and predict what caused that to happen. What questions did this activity generate for you?

Objective: I am able to classify and describe substances based on their properties.

Working with your elbow partner, identify the parts of in one of the stories.

Now flip stories with the students on the other side of your table and repeat the process.

Discuss your conclusions. Were they the same? Why or why not?

Let's Tie This All Together

Physical Science is any of the natural sciences dealing with inanimate matter or with energy, as physics, chemistry, and astronomy.  This branch of science is primarily concerned with the nature and properties of matter and energy and include topics such as mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms. It also includes chemistry which is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

properties of this item? What are the properties of this item?

Even though these are both paper clips, they have different properties because they are made of different materials. Properties are different from characteristics

Physical Properties: characteristics that can be observed and measured without changing the chemical makeup of the substance

What properties could you use to describe a material? ** Several items are in your group’s envelope ** Make a table and list the properties of each item Item Properties Paper clip Toothpick

Item Properties Unique List one or more properties that could be used to distinguish each material from all of the others. Item Properties Unique Paper clip Toothpick
