What Should We Flip?, Jerrid Kruse
What Should We Flip?, Jerrid Kruse
Iowa Science Teachers Journal
Educational fads are nothing new. Renaming or repackaging of old ideas are also not new. Indeed, anyone who has been in education for more than a few years will recognize how the pendulum of educational reform swings back and forth. Unfortunately, although things “change,” the change is not typically accompanied by “improvement” on a grand scale. One current trend is the notion of “flipping” or the “flipped classroom”.
Thinking Outside The Box: Using A Black Box Activity To Kick Off The School Year, Amanda Weeks, Stephanie Schemmel
Thinking Outside The Box: Using A Black Box Activity To Kick Off The School Year, Amanda Weeks, Stephanie Schemmel
Iowa Science Teachers Journal
This article discusses our approach to the first days of school. Students' first experiences in our classroom set the tone for the rest of the year. We start out the year with a black-box activity to engage students and begin helping our students understand the nature of science. This activity promotes National Science Education Standards G and Iowa Teaching Standards 1, 3, 4, 5, 6, and 8.
Searching The Web: Observing Spiders To Learn How Different Structures Serve Different Functions, Courtney King
Searching The Web: Observing Spiders To Learn How Different Structures Serve Different Functions, Courtney King
Iowa Science Teachers Journal
Through exploration and small group discussion, first grade students made connections between physical structures of organisms and their function. Additionally, students explored various spider “homes”. This activity promotes National Science Education Content Standard C.
Schools In Balance: Comparing Iowa Physics Teachers And Teaching In Large And Small Schools, Trevor Kittleson, Jeffrey T. Morgan
Schools In Balance: Comparing Iowa Physics Teachers And Teaching In Large And Small Schools, Trevor Kittleson, Jeffrey T. Morgan
Iowa Science Teachers Journal
In 2009 we surveyed all known Iowa high school physics teachers to gain insight into their educational backgrounds, instructional styles, content coverage, and available resources. Based upon a suggestion made at a subsequent presentation, we reexamined the collected data, comparing the responses of teachers from small and large schools to see if there were notable differences between the two populations. We found that teachers at larger schools teach a wider variety of physics courses, including more advanced and “physics first” style courses, and report stronger educational backgrounds in physics. While larger schools also have more financial resources allocated for physics …
Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal
Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal
Journal of the Iowa Academy of Science: JIAS
A carbon index (Cl) is one of many soil quality indicators that depends on organic carbon concentration. One of the values of a soil carbon index is in determining the impact of agriculture practices (i.e., tillage, crop rotation, N management, etc.) on soil organic matter status of mineral soils. Interactions of climate, parent material, topography, time, and organisms including human activities influence soil organic carbon (SOC). This study developed a soil carbon index for mineral soil map units in Iowa using data collected by the Iowa Cooperative Soil Survey Laboratory and the USDA Soil Survey Laboratory for over 2,300 soil …
Perspectives: Developing And Defining Both Science And Science Education As Disciplines, Robert E. Yager
Perspectives: Developing And Defining Both Science And Science Education As Disciplines, Robert E. Yager
Journal of the Iowa Academy of Science: JIAS
The six "domains" have been identified as features for the "doing" of science. These six are: Concept, Process, Creativity, Attitude, Application, and Worldview. They are offered to affect teaching, student learning, as well as a new way of defining science. Concepts and Processes often are the only two typically used to define school and college science content; Creativity and Positive Attitudes are added as two "enabling" domains; a fifth Domain is offered as a focus on the Application of typical concepts and process skills. It is the Domain where and how most people live and operate! The sixth Domain is …

Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch
Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch
Journal of the Iowa Academy of Science: JIAS
Bloodroot (Sanguinaria canadensis L., Papaveraceae) is a plant rich in benzophenanchridine (isoquinoline) alkaloids such as sanguinarine and chelerychrine. Both isolated alkaloids and whole-tissue rhizome extracts have demonstrated in vitro anticarcinogenic (antiproliferacive) activity in limited immortalized cell culture models, but the relative contribution of various alkaloid constituents to whole-tissue extract activity, and whether or not various alkaloids may act synergistically, has not been investigated. We challenged four immortalized cell lines (Jurkat, K562, Ramos, U937) with various doses of chelerythrine, sanguinarine, and berberine (a structurally and functionally similar alkaloid absent from bloodroot), alone and in all possible combinations, and measured proliferation …

Evidence From Detrital Zircon Ages For Middle Pennsylvanian Uplift And Drainage In The Source Area Of The Chariton Conglomerate And Marmaton Group Sandstones, Southern Iowa And Northern Missouri, Scott Mcfadden, Steven H. Emerman, Jane Pedrick Dawson, Kevin A. Rey, Tracy Kemp Anderson
Evidence From Detrital Zircon Ages For Middle Pennsylvanian Uplift And Drainage In The Source Area Of The Chariton Conglomerate And Marmaton Group Sandstones, Southern Iowa And Northern Missouri, Scott Mcfadden, Steven H. Emerman, Jane Pedrick Dawson, Kevin A. Rey, Tracy Kemp Anderson
Journal of the Iowa Academy of Science: JIAS
The Chariton Conglomerate is a quartz/limestone conglomerate of Middle Pennsylvanian age sparsely exposed in southern Iowa and northern Missouri. In Iowa it is characterized by quartz granules and rounded crinoid columnals. The objective of this study was to use detrital zircon ages to determine the provenance of the Chariton Conglomerate and possibly associated Marmaton Group sandstone beds. Detrital zircon ages were obtained for five conglomerate and two sandstone beds of the Chariton Conglomerate in Iowa, three conglomerate beds of the Chariton Conglomerate in Missouri, and two sandstone beds of the Marmaton Group in Iowa. According to the Kolmogorov-Smirnoff Test, the …
Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald
Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald
Journal of the Iowa Academy of Science: JIAS
Harlan's ground sloth, Paramylodon harlani, is documented for the first time from Iowa. The record is based on a fifth metacarpal recovered from a gravel bar within West Tarkio Creek, Page County. While the specimen was not found in situ, and could not be radiocarbon dated, the local geology suggests that it was probably derived from sediments that post-date Peorian loess deposition and is late Wisconsinan in age. This specimen extends the range of Paramylodon 350 km ro the northeast of the closest previously known locality. Its size is slightly larger than average for other late Pleisrocene (Rancholabrean) …
