1. DE Science Elementary 5-Minute Prep for Matter Properties of Matter Mass and Weight

2. Mass and Weight – The Big Ideas All matter has mass and takes up space. Gravity produces weight based on the mass of an object. On Earth, a scale measures mass of matter. In space with no gravity present, an object has mass but no weight. Liquids have mass. Air and other gases have mass. The mass of any object or material is equal to the sum of the mass of its parts.

3. Mass and Weight – Prior Knowledge Students often confuse mass and weight. It will help for students to use the FUN-damental, Whats the Matter, to review mass and weight. It will be helpful if students have been measured when they step on a scale at the doctors office or at home.Whats the Matter

4. Mass and Weight – Common Misconceptions Mass and weight are the same and they are equal at all times. –Reality: On Earth, a scale measures mass of matter, but in space without any gravity present, an object has mass but no weight. Gases do not have mass. –Reality: Gases are matter, which means they have mass and occupy space.

5. Mass and Weight – Using DE Science Content When you close this presentation, you can review the following recommended resources for Mass and Weight. Exploration: Mass and WeightMass and Weight Reading Passage: Camels in SpaceCamels in Space Video: Gravity and MassGravity and Mass Video: Measuring GasesMeasuring Gases Use the PowerPoint version of this presentation for hyperlinks to these resources or you can get to them through the browser or search feature.

6. Mass and Weight – Instructional Ideas Blow up one balloon fully and another balloon half way for each pair of students. –Have each pair of students place the balloons on the end of a long dowel and then hang the dowel from the center to measure the weight in a mock scale. –Ask students to describe what they have observed. –Then, have students explain either verbally or in writing why the two balloons are not balanced.

7. Mass and Weight – Instructional Ideas As a class and after exploring the video and exploration, construct a concept map of mass. –Make sure that students include and branch out concepts involving gravity as well as each state of matter.
