Isochron Dating

These exercises can simulate various earth science processes and offer instructors unique learning activities for their students. In we started to build and make available through the Internet activities which focus on the learning and teaching of earth science topics for introductory college and high school courses. These activities, listed in the chronological order of their development, are: To provide instructors with a permanent record, a personalized and printable “Certificate of Completion” is awarded to each student at the satisfactory completion of each activity. During Spring quarter of , these exercises were successfully completed by approximately , college and high school students from nearly colleges and high schools. To date, in excess of one million students have completed at least one of these activities. Various assessments of these activities and the voluntary feedback from approximately instructors has been positive over the years. Generally, instructors seek more similar on-line activities as enhancements to teaching and learning. A complete revision of Virtual Earthquake is now available with many new features and a built-in assessment tool for learning outcomes.

With the support of a series of NSF awards, several additional applications were developed in the areas of biology and earth science. These have been organized into four application suites: Virtual Courseware for Inquiry-Based Science Education consists of Drosophila, described above, and two other applications to be released soon: Natural Selection, which allows students investigate the evolution of traits by performing laboratory experiments involving water fleas, and Relative Dating, where students can pose and test hypotheses regarding the order of the geological events represented in a geological cross section.

Virtual Courseware for Earth and Environmental Sciences includes two groups of activities. Also available is a version called Terremoto that is completely in Spanish.

References Generic Radiometric Dating The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth. The equation is the one which describes radioactive decay: The variables in the equation are: Pnow – The quantity of the parent isotope that remains now. This is measured directly. Porig – The quantity of the parent isotope that was originally present. This is computed from the current quantity of parent isotope plus the accumulated quantity of daughter isotope.

Standard values are used, based on direct measurements. Solving the equation for “age,” and incorporating the computation of the original quantity of parent isotope, we get: Potential problems for generic dating Some assumptions have been made in the discussion of generic dating, for the sake of keeping the computation simple. Such assumptions will not always be accurate in the real world. The amount of daughter isotope at the time of formation of the sample is zero or known independently and can be compensated for.

No parent isotope or daughter isotope has entered or left the sample since its time of formation.

Africa Geologic History and Paleontology Assignment: The Virtual Dating Lab You are probably wondering Where do these numbers come from? Well, the ages are obtained from rock samples that have been dated radiometrically, which means using the natural radioactive decay of specific elements to determine the age of the sample. This Virtual Dating Laboratory exercise will help you to understand how radiometric dating techniques work. You must complete this online exercise in one sitting — meaning, this is not a module that you can start and come back to.

Please leave yourself at least a half hour to complete this lab. At the end of the exercise, you will be asked to enter your name please use your full name, no nicknames and your school please enter your Penn State campus location.

Smart Science real online science labs provide instructors and students with uniquely hands-on real lab experiments instead of simulations. Students collect data interactively from real experiments point-by-point using their own care and judgment just as in traditional labs.

They predict or hypothesize before or during the experimental activity. The Smart Science approach ensures that students understand the nature of science, learn scientific thinking skills, and come to appreciate the complexity and ambiguity of empirical work. Smart Science labs include quizzes and online lab reports showing all student lab data and more. Daily Tides Real lab.

Practical Considerations Individual Activities Collaborative Activities An Example of a Collaborative Activity Justification Research has shown that online instruction, including hybrid courses that involve some face-to-face instruction coupled with online components, can be just as effective as traditional face-to-face courses in providing high-quality learning experiences Dept. Recent advances in technology, coupled with changes in how today’s students interact with technology, require that traditional face-to-face pedagogies that often rely on visual and auditory cues be modified if they are to be effective in the online environment.

This often requires that instructors: There are many resources on the web that speak to best teaching practices for teaching online.

This activity promotes inquiry-based learning and the scientific method because it allows students to propose hypotheses, design their own experiments, and collect and analyze data to test these hypotheses in an engaging virtual environment that mimics a laboratory setting.

Virtual Dating: Isochron & Radiocarbon Dating A18 – page 2 A18 National Science Education Standards – Inquiry Design and conduct a scientific investigation. Use appropriate tools and techniques to gather, analyze, and interpret data.

Standard Students will investigate changes in Earth’s crust and climate. Objective Model Changes in the earth’s surface. Intended Learning Outcomes 1a. Make observations and measurements. Use reference sources to obtain information. Analyze data and draw warrented inference. Construct models and simulations to describe and explain natural phenomena. Scientists use radioactive dating to determine the time in years ago that an event happened.

Radioactive dating requires the use of a decay curve. In order for students to understand what a decay curve is and how to use it, the following activity is helpful. 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.
