The module is an integrated unit which addresses the following National Science Education Standards: *Science as Inquiry: Students develop the abilities necessary to do scientific inquiry identify questions, design and conduct scientific investigations, use appropriate tools and technologies to gather, analyze and interpret data, think critically and logically to make the relationships between evidence and explanations, communicate results, and use mathematics in all aspects of scientific inquiry.
*Life Science: Fossils indicate that many organisms that lived long ago are extinct.
They not only enjoyed this activity, but they really gained a better understanding of it as well.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.
Skills: -critical thinking -data analysis -questioning -graphing and data collecting Vocab Words: 1. This activity can be adapted for older students, but is used in an 8th grade earth science classroom.
During each trial, students record the number of radioactive parent isotopes and record this in a data table.
Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards.
Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
Students should recognize each time the number should go down by appx half.
Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives.
Once all groups finish, each group records their info on the class decay table (on the board) and we calculate the averages of the class. Isotope Concepts: Students should begin to see the pattern that each time they dump out their M&Ms, about half become stable.
