What is Matter and the Law of Conservation of Matter? Essential Question: What is Matter and the Law of Conservation of Matter? Standard: S8P1g. Identify and demonstrate the Law of Conservation of Matter Instructional Approach(s): The teacher should introduce the essential question and the standard that aligns to the essential question

Matter Anything that has mass and takes up space (volume) Instructional Approach(s): The teacher should introduce the slide and the students should record the definition of matter on their graphic organizer (linked on the curriculum map)

Mass Mass is the amount of matter in an object The mass of an object is the same no matter where in the universe the object is located The only way to change the mass of an object is to change the amount of matter that makes up the object Instructional Approach(s): The teacher should present the information on the slide while the students record important information about Mass on their graphic organizer

What’s the difference between mass and weight? Weight is a measure of the gravitational force exerted on an object. An object’s weight can change depending on its location in the universe. Instructional Approach(s): The teacher should present the information on the slide

Volume All matter takes up space. The amount of space taken up, or occupied, by an object is known as the object’s volume Imagine a speck of dust. Even the tiniest speck of dust takes up space. Another speck of dust cannot fit into that space without somehow bumping the first speck out of the way Instructional Approach(s): The teacher should present the information on the slide while the students record important information about Volume on their graphic organizer

Quick Lab: Space Case Instructional Approach(s): teacher demonstration or student activity showing matter takes up space even if you cannot see it (see the Space Case link on the curriculum map for more details)

Study Jams: Properties of Matter [Introduces Density] Instructional Approach(s): The teacher should show the short video to introduce the properties of matter. The video introduces the concept of Density which will be discussed in detail in Essential Question 5

Measuring Mass and Volume of Objects [conduct simple labs on measuring mass and volume] Instructional Approach(s): This would be a good place in the lesson to allow students to measure the mass and volume of objects. The activity will depend on the resources in your building. However, each building should have triple beam balances, graduated cylinders, and mass/weight sets

Distributed Summarizing: Light, Heat, Energy, and Sound are NOT considered Matter. Explain why these are not considered Matter. Instructional Approach(s): Have students turn to a partner and discuss the question on the slide. Partners can be determined by the students or the teacher can provide more specific directions such as turn to the person directly in front/behind you or to the right/left of you, etc. It may be necessary to have a group of three if you have an uneven number of students. Do not allow more than 30 seconds to 1 minute of discussion time. The teacher should be walking around listening and redirecting discussions as needed. The teacher can briefly discuss student responses.

Law of Conservation of Matter Lab or View the Baking Soda/Vinegar lab video clip Based on this lab, what do you think the Law of Conservation of Matter says? Why? Instructional Approach(s): The students should conduct the Law of Conservation of Matter Lab (see the curriculum map) or the teacher can demonstrate the lab. If it is not possible to conduct the lab, show the video clip of a similar lab. After conducting the lab or watching the video, ask the students what they think the Law of Conservation of Matter says and why based on the lab. If students need help drawing conclusions based on the lab, ask “What does Conservation mean?” and use the word conservation to facilitate the conversation

Law of Conservation of Matter [Mass] Matter cannot be created or destroyed, it only changes form. Instructional Approach(s): The teacher should present the information on the slide while the students record important information about the Law of Conservation of Matter on their graphic organizer

Law of Conservation of Matter [Mass] 2 Graham Crackers + 1 Marshmallow + 1 chocolate = 1 Smore Instructional Approach(s): The teacher should use the information on the slide to demonstrate the Law of Conservation of Matter All the ingredients are still there, just in a different form.

Law of Conservation of Matter [Mass] Video Clips https://www. youtube Instructional Approach(s): The teacher should show the short video clips illustrating the Law of Conservation of Matter

With a seat partner, discuss a real-world example of the Law of Conservation of Matter that you have experienced. Instructional Approach(s): Have students turn to a partner and discuss the question on the slide. Partners can be determined by the students or the teacher can provide more specific directions such as turn to the person directly in front/behind you or to the right/left of you, etc. It may be necessary to have a group of three if you have an uneven number of students. Do not allow more than 30 seconds to 1 minute of discussion time. The teacher should be walking around listening and redirecting discussions as needed. The teacher can briefly discuss student responses.

Law of Conservation of Matter [Mass] Instructional Approach(s): The teacher should use the illustration on the slide to show the Law of Conservation of Matter

The Law of Conservation of Matter will be a constant theme throughout this unit.

Summarizing Strategy: Matter Acrostic Instructional Approach(s): Each student should complete the summarizer. The teacher should use the summarizer to determine the level of student mastery and if differentiation is needed.
