Dendrochronology: Tree Ring Dating
This activity provides a basic knowledge of the principle of tree ring dating by using simulated core samples. Students first determine the age of a “tree cut down in 2019” then extend their understanding of tree ring correlation by determining the age of a “tree cut down” decades ago.

Scientific Concepts
•Patterns can be used to identify cause and effect relationships.
•Science assumes that objects and events in natural systems occur in consistent patterns that are understandable through measurement and observation.
•Growth of organisms are limited by access to resources.
•Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time.
Key Vocabulary: annual ring, bark, dendrochronology, pith, tree core

Kit #481EClimate Change: Organisms as Climate IndicatorsThere have been many recent news reports and scientific studies concerning climate change. Based on several lines of evidence, scientists have determined that in the past, average global temperatures have been significantly lower as well as significantly higher than today (e.g. Pleistocene ice ages with glaciers and woolly mammoths, as well as Paleozoic...

Kit #406SExamining Fossils
Fossils provide important evidence about changes in life on Earth. This kit provides students with the opportunity to handle and examine eight different fossils from various localities and geologic ages. Fossils of species that are no longer living provide evidence for extinction; fossils of species similar but not identical to those alive today provide...

Kit #450Radioactivity and Half-Life
Students simulate and measure radioactive decay by using simulats® (simulated radioactive atoms). They then use their data to create decay graphs and determine the half-life. To extend their understanding, they use known half-lives of actual radioisotopes to estimate the ages of ancient artifacts or fraction of the isotope remaining in those artifacts.

Kit #555SOrganisms as Indicators of Ecosystem Health
Students examine simulated samples of aquatic macroinvertebrates from the same river collected at three different points in time. They calculate the relative proportion of macroinvertebrates that are intolerant to pollution compared with the total catch. These proportions are an indicator of water quality. They identify patterns in the data and construct arguments for possible...
