Fossil dating worksheet
There are no "right" answers for this worksheet—just some practice drawing conclusions about how a fossil ended up in the site.
This worksheet makes a great companion to second-grade earth and space science lesson plans.
This is not to be confused with the statistical probability of the change in the population over time as demonstrated with an individual group's data during the M&Ms activity.
If such allergies occur, use a substitute material such as pennies.
Therefore, the teacher should state and enforce a no throwing rule of materials.
The M&Ms can be eaten by the students at the end of the activity.
Assessment: Have students explain in their own words the concept of half-life in radioactive decay, demonstrate how the rate of radioactive decay and the buildup of the resulting decay product are used in radiometric dating of rocks, and compare and contrast individual statistical data results to the class average of various statistical data results to determine reliability and predictability of the two groups.
Elaboration Have students research a radioactive isotope of their choice and find the following information: Math Connections: During the engagement activity students observe what occurs in a population of M&Ms over time due to random chance.
