Matter and Energy Chapter 1

Bell Work 1. What is the volume of a box that is 10 cm long, 3 cm wide, and 2 cm high? 2. What method do you use to find the volume of an irregular shaped object?

1.1 Vocab Matter – anything that has mass and takes up space Mass – measure of how much matter an object has

1.1 Vocab Weight – the downward pull on an object due to gravity Volume – the amount of space an object takes up. (for a regular solid length x width x height)

Bell Work – Write down these vocab words on your bell work sheet. Particle – a very small piece of matter, such as an atom, molecule, or ion Substance – matter of a particular type. Elements, compounds, and mixtures are all substances

Bell Work Decide if these statements are true or false. If false correct them. 1. Substances you can see are matter, but substances you cannot see are not matter. 2. Mass and weight are the same thing. 3. Formulas can be used to calculate the volume of many solids with a regular shape.

1.2 Vocab Atom – the smallest basic unit of matter Molecule – two or more atoms that have bonded together

Bell Work 9/30/09 Please get a 1.1 Quiz Worksheet off my desk and complete the 1.1 Quiz side. You can use your notes or the book.

Bell Work 1. Give 3 examples of solids 2. Give 3 examples of liquids 3. Give 3 examples of gasses

Bell Work Please write complete sentences 1. What are atoms? 2. Why do dust particles in the air appear to be moving in different directions? When Finished study for test

Bell Work Write each sentence then write down the term that matches it: matter, volume, atom, weight, molecule 1. The smallest basic unit of matter 2. A particle made when two or more atoms combine 3. Anything that has mass and takes up space

1.3 Vocab Element – consists of atoms of only one type. Compound – a substance made up of 2 or more different types of atoms bonded together. Mixture – a combination of 2 or more substances. Do not combine chemically and can be separated by physical means.

Heterogeneous mixture: a mixture that has different properties in different areas of the mixture (is not the same throughout) Homogeneous mixture: a mixture that is evenly spread throughout (is the same throughout)

Bell Work 10/6/10 Make the following chart for mixtures and compounds. Use page 24 for help. MixturesBothCompounds

Bell Work 10/7/10 1. Give 2 examples of a heterogeneous mixture. 2. Give 2 examples of a homogeneous mixture.

Bell Work Indicate whether each of the following describes an element, compound, or mixture 1. Silver 2. Koolaid 3. Salt 4. Copper

Bell Work 1. What is a heterogeneous mixture? 2. What is a homogeneous mixture?

Bell Work – Fill out the chart about mixtures HeterogeneousBothHomogeneous

1.4 Vocab States of matter – different forms in which matter can exist. Solid- a substance that has a fixed volume and a fixed shape.

1.4 Vocab Liquid – has a fixed volume but does not have a fixed shape. Gas – has no fixed volume or shape.

Bell Work List the three states of matter and fill in squares showing the movement of the particles.
