The activities include an online assessment quiz that consists of randomized interactive questions.
The students’ answers are graded automatically and stored in a database server, and a printable certificate of completion is issued for each student.
Standard 3240-05 Students will investigate changes in Earth's crust and climate. The process of obtaining radioactive dates from samples is also shown.
Objective 3240-0501 Model Changes in the earth's surface. Observations: What are the two sides of a penny called?
The instructor can access student and class results, allowing them to quickly gauge how well the key concepts were understood.
The simulations are designed to enhance traditional curricula and provide a supplement to experimental laboratory and field work.
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.
Construct models and simulations to describe and explain natural phenomena.
If you flip a penny, what are the two ways the penny can land?
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.
