You can find the mass of air by taking a sandwich bag and weighing it before with nothing in it. Then you blow it up with air and weigh it again. You will find it has a greater mass than before. ]]> 2017-02-08 14:48:06 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/152476559 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/152946421 Everything has mass, even air.  You can find the mass of air by taking a sandwich bag and weighing it before with nothing in it.  Then you blow it up with air and weigh it again.  You will find it has a greater mass than before. That proves that air has mass. ]]> 2017-02-09 23:44:23 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/152946421 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153195745 Everything has mass from air to water because everything has density. For instance water has a density of 1 which proves it has mass because for something to have density it has to have mass and volume because density is determined by mass divided by volume. ]]> 2017-02-10 23:17:44 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153195745 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153423766 All things on Earth have mass. This is true because everything has density. Water has a density of 1 which means it has to have mass because all things with density have mass. Density is determined by dividing mass by volume. You can find that air has mass by weighing a baggie before and after blowing it up. When you weigh it after blowing it up it will be more. This proves that everything has mass.  ]]> 2017-02-13 14:15:43 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153423766 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153434086 All things have mass like a ball with no air in it and then weigh it. You will see if you put air in the ball and weigh it, it will have more mass.]]> 2017-02-13 14:40:37 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153434086 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153600207 All things on Earth have mass, including the air. I can support my statement with the evidence that everything has density. Water has a density of 1 which shows that is has mass because for an object to have density it has to have mass and volume since you calculate density by mass divided by volume. You can find the mass of air by for example weighing a balloon before and after blowing it up. This shows that everything has mass and atoms make up everything on this Earth so that claims that atoms make up the mass of all materials.]]> 2017-02-14 00:47:30 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/153600207 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/154309850 Everything in Earths atmosphere has mass. I know this because I learned that everything has density. To have a density, it has to have mass and volume. You can see air by how much is in a balloon. This all shows that everything has mass. Everything has mass on earth so this shows that atoms make up everything on earth.]]> 2017-02-16 14:20:02 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/154309850 jboyle10 https://padlet.com/jboyle10/wdzhgb9sl9in/wish/157384226 2017-03-02 16:22:39 UTC https://padlet.com/jboyle10/wdzhgb9sl9in/wish/157384226
