Access Point (if applicable) Learning Objective: What will the students know and be able to do as a result of this lesson? What is the concept you want the students to learn?

Students will demonstrate that mass is conserved when physical and chemical changes occur. Students will show how mass is saved when substances change.

Guiding Questions: What are the guiding questions for this lesson? Provide specific amount of directives to the student.

What do physical and chemical changes have in common? Why does mass seem to change? How the law of conservation of mass is seen in everyday life?

Prior Knowledge: What prior knowledge should students have for this lesson?

Definitions and differences between matter, mass and weight. Differentiate between physical and chemical properties of matter. Law of the conservation of mass.

Introduction: How will the teacher introduce the lesson to the students?

Activity - Why does mass seem to change? Show pictures of shinny and rusty nail. Beneath each picture, indicate the mass of each object by placing an M under the shinny nail and an M + m under the rusted nail. Ask students where the additional mass came from? Compare this with the loss of mass by a piece of wood when it burns.

Investigate: What question(s) will students be investigating? What process will students follow to collect information that can be used to answer the question(s)? Debate, cross-examine, rebuttal, devil's advocate.

Activity – Mass doesn’t change – Students will verify that mass remains unchanged during a physical change. Materials (sugar cube, clear plastic wrap, balance, and metal spoon) Wrap a sugar cube in clear plastic wrap and measure the mass of the cube and plastic wrap. Use a spoon to carefully crush the sugar cube. Do not tear the plastic wrap. Measure the mass of the crushed sugar and plastic wrap. Studnets answer, what is true about the mass of the object before and afte undergoing a physical change?

Analyze: How will students organize and interpret the data collected during the investigation? What activity can the students explore to make the realization?

Activity – What’s in a change? – Materials (colored pencils, two hydrogen molecule models, one oxygen molecule model, plain paper) Examine the hydrogen and oxygen molecule models. Using colored pencils, sketch each molecule on your paper. Label the sketch with the different parts of the molecules and the chemical formula for each molecule. Recall the chemical formula for water. Observe the molecules and predict how to combine the molecules and sketch a water molecule. Use the hydrogen and oxygen models to build a new model of a water molecule. Answer the following questions: What happened to the hydrogen and oxygen molecules to make a water molecule? What chemical process does this model? How is the water molecule different from the oxygen and hydrogen molecules? What process took place when the hydrogen and oxygen molecules combined into water? How does this activity illustrate the law of conservation of mass?

Closure: What will the teacher do to bring the lesson to a close? How will the students make sense of the investigation? What's the learning moment?

Describe a way the law of conservation of mass can be applies to daily life. Make a multimedia presentation in which the physical and chemical changes that occur while cooking are identified.

SUMMIT Teaching the New Standards Accommodations: Describe how to accommodate students with special needs and how to differentiate instruction.

Groups or create a poster or collage instead of multimedia presentation that shows both physical and chemical changes occurring in matter. Label and describe the physical and chemical changes

Extensions: Describe possible extension of this lesson. Extend and evaluate: - Homework - Individual Activity - Review - Assessment

Divide the class into groups. Each group will conduct research on how temperature affects chemical changes. Then each group will combine research into a single multimedia presentation to show the class.
