Seeing this connection will help students to understand how scientists can determine the age of a sample by looking at the amount of radioactive material in the sample.
If two nuclei have different masses, but the same atomic number, those nuclei are considered to be isotopes.
The MMS class were a class of 402 coastal minesweepers built for the Royal Navy between 19.
They were of wooden construction to counteract magnetic influence mines.
Rather, the atoms decay at a rate that is characteristic to the isotope.All three isotopes have the same atomic number of 6, but have different numbers of neutrons.Carbon-14 has 2 more neutrons than carbon-12 and 1 more than carbon-13, both of which are stable.This experiment is best used by student working in pairs.Grade Level: 5-12 grade Disciplinary Core Ideas (DCI) 3-5ETS1-2, MS-ESS1-4, HS-ESS1-6 Time for Teacher Preparation 40-60 minutes – To gather materials Activity Time: 40-60 minutes (1 Class Period) Materials: Objectives Students try to model radioactive decay by using the scientific thought process of creating a hypothesis, then testing it through inference.
