Grade: 10th
Subject: Physical Science
States of Matter: Solids, Liquids, and Gases
- Physical Science
- Chemical Science

Solid- A state of matter in which it has defined volume and shape

Gas- A state of matter in which there is no defined shape or volume

Liquid- A state of matter where there is no defined shape but there is defined volume

Phase Change- The Reversible physical change that occurs when a substances changes from one matter state to another.

Absolute Zero- 0 degrees on the Kelvin scale

Kinetic Energy- Energy an object possesses while in motion

Plasma- The state where matter where atoms have been stripped of their electrons

Expected Outcome Of This Lesson Plan-
1. Students will be able to recognize the 4 phases of matter: solid, liquid, gas, and plasma.

2. Students will know the definition of a Phase Change and how it relates to the changes that matter goes through (i.e melting and freezing).

3. Students will have a clearer understanding of how these different states of matter act at the atomic level and how that allows them to have their specific properties.

4. Standards: Physical Science, Science and Technology
Teacher Objectives-
Understand the essential question of how matter matter acts at it's different stages.

1. The Students will understand the aspects of Kinetic Energy and the important points of what makes up the formula for Kinetic Energy.

2. The Students will know the aspects of each phase of matter.

3. The Students will be able know the special qualities that each phase of matter has and how that makes them unique compared to other phases, even of the same item.

4. The Students will understand how phase changes happen and the processes of changing that matter must go through to reach a new state.

5. The Students will know how temperature plays a vital role in allowing phase changes to happen and shift between solid, liquid, and gas.
1. Solids, Liquids, and Gases Handout

2. Physical Science: Concepts in Action Text Book
Teaching Methods-

1. Lesson Introduction-

1. The teacher will be in front of the class and visible to all students

2. The teacher will read along with the worksheet and ask the class to fill in the blanks

3. If the class has difficulty answering the question for each blank the teacher will tell the class the correct answer

2. Lesson Progression-

1. By presenting to the whole class and asking the class the questions the activity becomes more interactive and engaging to the students.

2. With a class wide activity such as this any students with questions as to the correct answer will not miss the answer as it is being told to the class as a whole and not to individual students.

3. Following the end of the discussing involving the worksheet an animated demonstration of the movement of molecules in different phase states will be shown to give a visual account of how it looks in an effort to provide a visual representation of an important part of the lesson.

3. Guided Practice-

1. The teacher will read through the worksheet and progress to the different sections, addressing the asked questions.

2. The teacher will then ask the class to answer the desired question being asked at the appropriate section of the worksheet.

3. The Teacher will go over any section or particular question the class is having difficulty with.

4. Student Practice-

1. A Homework Assignment from the students text book will be assigned as a way of reading how much they learned from the lesson and how well they apply it without the teacher's assistance at home.

2. Students would then turn in these assignments for grading on how well they understood the concepts covered in this lesson

5. Learner Accommodations-

1. If any student requires special aid for any documented reason the teacher will do so and work with any additional personal required

6. Assessment-

1. The students will fill out a "ticket at the door" where before they leave they write down a response to three questions about the lesson and then turn those questions into a box by the door before they leave.

2. This method allows the teacher to gain immediate feedback on how effective the lesson was and how well different students in the class grasped information.

7. Lesson Closure-

1. At the end of the lesson the teacher will show the one animated visual aid (the molecules of a substance moving at different speeds depending on the phase it is in) and a three stage picture of ice in a container.

2. The ice picture will help show students how the form of ice changes during each phase. It begins as a solid block with shape and volume defined and then it is next a liquid that fills the box, taking the boxes shape but with still defined volume and next heated to steam inside the box where it has no defined volume or shape.
Measuring Student Progress-
1. Students will need to complete graph indicating changes in states of matter.
