Bell Work

Refer to Mr. Welliver’s Physical Science Class Outline to answer the following:

1. What percentage of your grade is based on tests and quizzes?

2. What are three ways of earning extra credit?

3. What must all students do if they have to leave during class?

Bellwork – Scientific Method

1. Use three of the words from the SCIENTIFIC METHOD word search list in a sentence or sentences.

Bellwork – Lab Safety

Think about dangers of working in a lab, then write three rules that would help keep people safe while working in a laboratory.

1.

2.

3.

Bellwork – Liquid, Gas, and Solid

Give an example of a liquid, gas, and a solid.

Bellwork – Textbook

What are some features most textbooks have to help you find information in the book? (List at least 2)

Bellwork – Matter Vocabulary

Use the words particle, energy, potential energy, and kinetic energy in at least one sentence. See the What Are We Learning About? wall for definitions.

Bellwork – Safety Posters

Before looking at the rule, can you guess what safety skill is being illustrated. Refer to pages 573 and 574 for a list of the safety skills.

As a group pick what you think is the best poster to show to the class.

Bellwork – States of Matter

1. What happens to the particles of ice as the ice melts?

2. Why does snow melt when you hold it in your hand?

Bellwork – States of Matter

Use the word state in at least one sentence.

SCIENCE USE V. COMMON USE – p. 256

state

Common Use a condition of mind or being. Before the big test, the students were in a nervous state.

Science Use a condition of matter. Three common states of matter are solid, liquid, and gas.

Bellwork – States of Matter

1. Define the words fixed and volume.

2. What state of matter has a fixed shape, and volume?

Bellwork – States of Matter

1. In random motion, how are particles moving?

2. If random motion is happening in all states of matter, why don’t we see motion on a solid like a boulder resting on the ground?

Bell Work – 6.1 Review

1. Describe the distance between particles in a solid, liquid, and a gas.

2. Describe the motion of the particles in a solid, liquid, and a gas.

Bellwork – States of Matter

Identify the correct state of matter:

1. Fixed shape and volume

2. Unfixed shape and volume

3. Fixed volume and unfixed shape

Bell Work – States of Matter

Identify the state of matter picture in each circle, give at least one reason for your answer.

Bell Work – States of Matter

1. What would happen to the volume of the air in the classroom if the volume of the classroom were doubled?

2. What would happen if the volume was cut in half?

Bell Work – States of Matter

1. If kinetic energy is the energy an object has because it is moving, why does a large boulder on the side of a mountain have kinetic energy?

2. Which state of matter has the most kinetic energy?

Bell Work – Oobleck Lab

Look over your lab from last week: Write down at least two things from the lab

that you had questions about.

Bell Work – Freezing

1. What state of matter was the water in before it was put into the freezer?

2. Compared to liquid water, how much space does solid water take up?

3. What problems might happen as a result of water expanding as it freezes?

Bell Work – Particle Motion

Which of the pictures on the right best represents gas particles in a hot air balloon? Explain.

higher temperaturehigher temperature

lower temperaturelower temperature

Bell Work – Changes of State

1. In what changes of states do the particles in a material become farther apart?

2. In what changes of state do the particles in a material become closer together?

Bell Work – Energy

1. What is the difference between potential energy and kinetic energy?

2. What is thermal energy?

Bell Work – Random Motion

What is an example of random motion? Explain your answer.

Bell Work – Thermal Energy

In what two ways can a material change when its thermal energy increases?

Bell Work - Test

1. What should you do to prepare for tomorrow’s Chapter 6 Test?

2. What are you allowed to use on the test?

3. What can you do to improve your grade after you take the test?

Bell Work - Atoms

An individual atom is so small that it would take 50 million of

them lined up in a row to equal one centimeter! Atoms, however, can be divided into

smaller parts, and, amazingly, some of these parts have

particles that are tinier yet.

1. Why do you think scientists have only recently discovered these subatomic particles?

2. What might scientists learn by breaking apart atomic nuclei?

Bell Work - Atoms

What do atoms look like? Has anyone ever seen an atom?

Bell Work – The Atom

1. How can you figure out what’s inside a wrapped box without opening it?

2. How is the above question like exploring the atom?
