Malaysian women webcam - Simulate carbon dating
Students should begin to see the pattern that each time they “take a half-life,” about half of the surrogate radioactive material becomes stable.Students then should be able to see the connection between the M&M’s and Puzzle Pieces and radioactive elements in archaeological samples.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.
Isotopes have the same chemical properties, but different physical properties.
An example of isotopes is carbon, which has three main isotopes, carbon-12, carbon-13 and carbon-14.
All three isotopes have the same atomic number of 6, but have different numbers of neutrons.
Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives.
Students are able to visualize and model what is meant by the half-life of a reaction.
