  1. Properties of Matter

  2. Think of a pop can… • Take a good look at the container. • You probably know that it is made up of metal aluminum, which is light and flexible, yet strong. • What other characteristics or properties does it have that make it useful for holding liquids? • Aluminum has many other applications… screen doors, cars, and airplanes all use aluminum.

  3. Aluminum is usually used in sheets or formed into parts. • But did you know that aluminum can also be made into foam?

  4. Aluminum foam… • Is an example of combining a variety of materials to create a new material with different properties than those of the original. • Mixing powdered aluminum with a foaming material makes aluminum foil, a substance that can be 10x stiffer & 50% lighter than aluminum. • It can also float because if has air pockets.

  5. Engineers use this new material to create lighter, safer cars. Aluminum foam is able to absorb more impact energy when a car is in a collision. • In this unit, you will be asked how to observe how matter changes and interacts with other matter. You will collect evidence of changes by: • Investigating the properties of matter • Interpreting observations & data from experiments. • Creating and interpreting models

  6. By the end of this activity, you should be able to answer these questions: • How do we determine the properties of a variety of different substances? • How do different substances interact? • What evidence can be used to indicate that an interaction between substances has occurred?

  7. Purpose: to observe what happens in a simple chemical reaction. • A chemical reaction is a chemical change which forms new substances. • A chemical reaction is a process that leads to the transformation of a one set of chemical substances to another. • Would new substances have new characteristics or properties than what you started with?

  8. Procedure: • Instructions for this lab are on page 91 of your text. • IMPORTANT: use the quantities written on the board, not in the amounts listed in the text. • To hand in individually: • Record your observations; written and hand drawn. • Questions 6 & 7, page 91
