1. Notes Science Essential Question(s) (1) What is mass? (2) What is weight? (3) How are they similar to each other? (4) How are they different from each other? (5) How do I measure each of these properties? (6) What are the metric units of measure for mass and weight? Tennessee SPI Objective: Distinguish between mass and weight using appropriate measuring instruments and units. Check for Understanding Make a foldable that compares and contrasts mass and weight. SPI 0807.12.4 Mass and Weight Instructions for Students 1) Make sure you view this presentation in slideshow mode. 2) You can find instructions about how to do this by doing a Google search or by searching YouTube. 3) After you have it in slideshow mode, press the right-arrow keyboard button to advance through the presentation. 4) If you need help, please communicate with your teacher.

2.  What is it?  How is it measured?  How can I tell the difference between mass and weight? SPI 0807.12.4 Mass and Weight Notes Science Mass Key Questions  Mass is the amount of matter in an object.  In other words it is how much "stuff" is in an object.  Everything that is made of matter has mass.  Anything that is solid, liquid, gas, or plasma has mass. Mass: What is it?

3.  We measure mass with a triple-beam balance or an electric balance (there are various kinds) Unit of measure for mass: Examples: milligrams (mg), grams (g), kilograms (kg) Mass: How is it measured?  We are measuring the amount of matter in the object  This measurement does not change from planet to planet Grams Triple-Beam Balance Electric Balance

4.  Mass does not change from planet to planet (weight does) Example: -A full/unopened can of coke on Earth has a mass of 390g. -same unopened can on Mars would have the same mass (390g) SPI 0807.12.4 Mass and Weight Notes Science EarthMars Earth Mars 390g Mass: How Can I Tell the Difference Between Mass & Weight?

5.  What is it?  How is it measured?  How can I tell the difference between mass and weight? SPI 0807.12.4 Mass and Weight Notes Science Weight Key Questions  Weight is the measure of gravity’s pull on an object.  Weight = mass of the object times the acceleration of gravity F.Y.I.-formula for weight is w = m X g  Everything made of matter can be affected by gravity. (This includes all solids, liquids, gases, & plasma). Weight: What is it?

6.  Measure weight by using a scale (there are various kinds)  We are actually measuring the force of gravity's pull SPI 0807.12.4 Mass and Weight Notes Science Unit of measure for weight: Weight: How is it measured?  This measurement changes from planet to planet Newtons (not pounds!)

7. EarthMars  Weight changes from planet to planet, but mass does not Example:  A full/unopened can of coke on Earth weighs 3.61 Newtons.  The same unopened can on Mars would weigh 1.20 Newtons Why? Mar has less mass than Earth. Therefore it has less gravity SPI 0807.12.4 Mass and Weight Notes Science Earth Mars 3.61 N 1.20 N Weight: How to Tell the Difference Between Mass & Weight
