Read the passage in this science printable to learn about the history of radioactive dating and its uses.
Students will answer comprehension questions and solve word problems using a table with information about the half-lives of radioactive elements.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. The most well-known of all the radiometric dating methods is radiocarbon dating.
Libby was awarded the Nobel Prize in chemistry for his work in 1960.
Atoms may stick together in well-defined molecules or they could be packed together in large arrays.
This is a slide and worksheet for radioactive dating and half life activity.
The Slides are to be shown at the front and then each item is shown in turn and the pupils use their graphs to calculate the age of each item from the percentage of carbon found in them. take longer than you think, but keeps them engaged and there're questions to be answered in their books also.
The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.
To be able to do this lesson and understand the idea of half-life, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.
