Aspects Of An Interior Stream Clam Midden From 1915 At Quasqueton, Buchanan County Iowa, Dennis W. Schlicht

Journal of the Iowa Academy of Science: JIAS

During clam surveys on the Wapsipinicon River in 1991 buried clams were observed in a bank of the river at Quasqueton, Buchanan County, Iowa. An interview with the landowner revealed that the clams were from a 1915 local clamming operation. Excavation and examination of many of the clams reveal interesting differences in species composition and size, when compared to more recent specimens from the river. Observations on the midden were recorded, species determinations were made and measurements were taken. Comparisons are made to two other modern surface surveys on the river. Differences were observed in both species composition and shell …

Introducing Students To Polar And Non-Polar Interactions Through Inquiry, Jerrid Kruse

Iowa Science Teachers Journal

Almost half of all chemistry teachers do not use inquiry in their classroom. Teachers cite classroom management, safety, and workload as reasons for not implementing inquiry techniques in their classroom (Deters, 2004). These teachers may resist laboratory-based inquiry finding it too daunting for themselves and their students. However, both students and teachers can progressively move to laboratory-based inquiry by first starting with less demanding science inquiry. This article describes an inquiry atmosphere created in a discussion classroom setting where students only minimally interact with materials. Students investigate macroscopic properties of water and hexane at their desks and the teacher performs …

The Unionid Mussels (Mollusca: Bivalvia: Unionidae) Of Missouri River Floodplain Ditches In Fremont County Southwestern Iowa And Atchison And Holt Counties Northwestern Missouri, Ellet Hoke

Journal of the Iowa Academy of Science: JIAS

A survey of ditches in the Missouri River floodplain in southwestern Iowa and northwestern Missouri resulted in the recovery of nine unionid mollusk species. The floodplain ditches may provide valuable habitat for mussels in a region that has suffered a tremendous decrease in productive aquatic habitats over the past sixty-eight years. Additional survey activity is needed to determine the complete inventory of unionid mollusks in the area.

Summer Soil Temperatures On Algific Talus Slopes In Northeast Iowa, Tom R. Cottrell, Kyle S. Strode

Journal of the Iowa Academy of Science: JIAS

Soil temperatures at 15 cm depth were recorded on a single occasion at multiple grid points on two algific talus slopes during the summer of 1999. To represent and compare soil temperatures over a wider area, soil temperatures were measured (less intensively) at five other algific slopes and three non-algific forested slopes. Algific slopes appear to have greater variation in soil temperatures than non-algific sites. Spatial variation in algific slope soil temperatures ranged from 4-25°C. During the 10 day sample period temporal variation in air temperature at a nearby weather station had a similar range. Isotherm plots reveal a heterogeneous …

Discordant Harmonies In Fingernail Clam Populations (Musculium Transversum) Of Mississippi River Backwater Lakes, Jim Eckblad

Journal of the Iowa Academy of Science: JIAS

The populations of Musculium transversum from 8 backwater lakes have been studied over a 29-year period based upon over 440 grab samples. These lakes in Navigation Pool 9 of the Upper Mississippi River (UMR) range in size from 2 to 255 hectare surface area, mean depths from 0.2 to 0.9 meters, with mean water exchange times from 0.5 to almost 57 hours. Samples from the 1989-91 period suggested summer Muscu!ium populations had declined to about 9 percent of their mid-1970 levels. Deterministic models have attempted to explain this decline. More recent sampling suggests a substantial recovery of Musculium populations (mid-summer …

Threatened By Industry, Saved By Science: Mussel Propagation At The Fairport Biological Laboratory, James Pritchard

Journal of the Iowa Academy of Science: JIAS

During the 1890s, people on the Mississippi River exploited mussel populations to support a thriving button industry. Within a brief time, they noticed significant declines in mussel populations, and called on the U.S. Bureau of Fisheries to save the resource. This paper discusses mussel propagation studies, techniques, and activities carried on in association with the Fairport Biological Laboratory (Iowa) from about 1908 to 1932. While scientists developed sophisticated techniques and had success in mussel propagation, changing habitat conditions in the river (caused mainly by pollution and dam construction) meant limited success in rescuing mussel stocks, while the introduction of plastic …

Before small group math instruction was implemented, students averaged approximately 61 % on chapter tests, while after its implementation students were scoring an average of 76%. Procedures included both pre and post test data analysis.

Small groups were created based on student achievement. There were three main groups: low, middle, and …

Implementing Distributed Practice, Christi Sires

Graduate Research Papers

Distributed practice is a daily routine where students are exposed to a math problem, asked to solve it, and then explain how they solved it. The idea of short intervals of instruction over a period of time can have remarkable results. This instructional strategy has been cited in numerous research studies, an indication that it may be successful in helping students better understand how they can solve mathematical problems.

This study will try to determine the growth of Jewett Elementary's first grade students as they were exposed to distributed practice over a period of time from first to second quarter …
