Ocean Drilling Distance Learning Program Overview z

Ocean Drilling Distance Learning Program

Overview z The Ocean Drilling Distance Learning Program (OD-DLP) at Texas A&M University builds on the exciting scientific research achieved by the Ocean Drilling Program to enhance middle school science education. The OD-DLP is made possible through the collaborative efforts of the College of Geosciences and the Ocean Drilling Program, and the e. Education Group in the College of Education at Texas A&M University.

Program Objectives z Increasing the technology hardware available in rural middle school science classrooms, z Providing professional development on technology integration into classroom instruction for middle school science teachers, z Providing earth science instructional materials electronically to rural middle school science classrooms. These objectives have been met by securing and delivering the essential hardware to participating schools

Instructional Design z A master teacher traveled on the JOIDES Resolution, for fifty-six days and taught weekly lessons to students z Seven twenty-minute lessons were taught z Students conducted problem-solving activities weekly and posed questions

Sample Lesson Slides: How Old is Old? Geologic Time Broadcast 4: February 7, 2001 Mrs. Joan Linsley

Relative vs. Absolute Time z. Relative: the age of a rock layer in relation to other nearby layers. The precise length of geologic time represented by any layer is often unknown. z. Absolute: the age of a rock or mineral in numbers of years. Sample Lesson Slides:

Geologic Time 1. 8 5. 0 23 38 54 65 135 192 280

Terms/Tools Determining Age z. Biostratigraphical Unit: definition of the boundaries of a rock layer based on the ages of fossils within it z. Lithostratigraphical Unit: definition of the boundaries of a rock layer based on the physical characteristics of the rocks within z. Chronostratigraphical Unit: division of a section of rock based on the absolute ages of the rocks within it z. Geochronology: development of a time- line of events relating to the deposition or creation of rocks in a given area Sample Lesson Slides:

Use of Fossils z Fossils provide a record of the slow, progressive development of life. z Through the use of index fossils, one may identify a particular layer of rock wherever it is exposed. z Scientists use fossils to identify ages of rocks throughout the world. Sample Lesson Slides:

Guest Dr. Michael Howell Paleontologist University of South Carolina These Sample Lesson Slides were used as the guest scientist presented concepts.

Time for Ask A Question!!

“ASK A QUESTION” z Mrs. Linsley, along with project scientists, answered student questions that were submitted through the Ask a Question system z The teacher on board highlighted students’ questions and scientists’ responses during each broadcast z All ASK A QUESTION responses are posted on the weekly A-A-Q response pages

ASK A QUESTION Example z Question: What exactly do you expect to find? Have you found any clues that there any life forms that have not been discovered yet? Name: Melissa School: Charlotte Middle School, Charlotte TX Response: We expect to find that there have been rises and falls in the sea level that drowned and exposed the reefs at various times. We will be investigating the times these occurred and the magnitudes of them. One of the scientists has found a foraminifer that appears to be different from those found here previously. There is an indication that there was a shallow lagoon here with sea grass because sea grass fossils were found. This was expected as a part of the reef system. We don't expect to find new life forms, but discovery is always possible. To take a look at some of the life forms we are finding, look at this page on calcareous nannofossils, and this page on foraminifers (mentioned in Broadcast 4 on Geologic Time). Some new life forms were discovered by other scientists as part of a seafloor system called a hydrothermal vent. Scientists didn't know that life could exist in such extreme conditions until they actually went to the vents to study them. To find out more about these newest seafloor forms of life, visit this page on seavents.

Journal Activity Examples Why do you think fossils are useful in finding ages of sediments? Fossils are useful for two important reasons: z They are found in many rocks and sediments in many locations around the world. Because they are widespread and have fixed periods of time in which the organisms lived, they are the most commonly used tool for identifying the ages of sediments and sedimentary rocks. Other age-dating tools, such as radiometric dating (absolute ages) cannot be used as often as fossils because of the lack of appropriate minerals to analyze with these methods…
