We found that battery electric cars generate All vehicles experience three distinct life stages: manufacturing, operation, and end-of-life.Each stage is linked with carbon dioxide and other greenhouse gas emissions—but those emissions differ between gas-powered cars and electric cars. Raw materials are extracted, refined, transported, and manufactured into various components that are assembled into the car itself.To help students understand the history of radioactivity, have them go to Radioactivity: Historical Figures, on the Access Excellence Classic Collection site, to read about the contributions of Wilhelm Roentgen, Antoine Becquerel, Marie and Pierre Curie, and Ernest Rutherford.As students read about these scientists, ask them to think about the following questions: Students can supplement this site with a visit to Isotopes Project.Tell students: "We measure our rate of speed in a car in miles per hour.
And as electricity becomes cleaner (which it is), the difference between electric cars and gasoline cars will only grow—cementing the role of electric vehicles in halving U. Your generous support helps develop science-based solutions for a healthy, safe, and sustainable future."Today we will simulate radioactive decay to understand what we mean by half-life.Radioactive decay, also known as radioactivity, is the spontaneous emission of radiation from the unstable nucleus of an atom." Have students go to the Isotopes Project website to look for more information about radioactive decay.The mathematics of inferring backwards from measurements to age is not appropriate for most students.They need only know that such calculations are possible. 79.) In this lesson, students will be asked to simulate radioactive decay by pouring small candies, such as plain M&M's® or Skittles®, from a cup and counting which candies fall with their manufacturer's mark down or up.
