Virtual radioactive dating lab
Modeling Atoms : Mini Rutherford Description: With the Mini Rutherford Activity, students deduce shapes and sizes of unseen objects by tracking the movements of objects they can see, in relation to the unseen…
See More Making Atoms Visible : Cloud Chamber Description: Allow students to visualize and understand ionizing radiation.
After the activity students can visit the Virtual Dating web site which allows them to use the mouse to obtain values from the decay curve in answering questions about the amount of radioactive element remaining in a substance.
In order for students to understand what a decay curve is and how to use it, the following activity is helpful.
However, to read any clock accurately we must know where the clock was set at the beginning.
Most people think that radioactive dating has proven the earth is billions of years old.
After all, textbooks, media, and museums glibly present ages of millions of years as fact.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.Grade Level 5-12 Disciplinary Core Ideas (DCI, NGSS) 5-PS1-1, MS-PS1-1, MS-PS1-4, HS-PS1-8, HS-PS4-2, HS-PS4-5 Time for Teacher…See More Irradiated Salt Demonstration Materials: Table salt (Na Cl) that has been irradiated with at least 180,000 RADs of gamma radiation. Radioactive dating requires the use of a decay curve. Introduction: Scientists use radioactive dating to determine the time in years ago that an event happened.
