Ecosystems, interacting systems of biotic and abiotic factors, are a fascinating topic in life science. The "Next Generation Science Standards" (NGSS Lead States 2013) recognize "Ecosystems: Interactions, Energy, and Dynamics" (HS-LS2) as one of four overarching ideas in life science that students should understand. Student…

Teachers are highly reliant on textbooks for teaching. In the Republic of Korea, science textbooks help students to understand scientific terms through inquiry activities. However, there is a lack of analysis on whether the inquiry activities suggested in these textbooks appropriately cover the terms included in the main text. Therefore, this…

This article reports the results of a randomized control trial of a semester-long intervention designed to promote ninth-grade science students' use of text-based investigation to create explanatory models of biological phenomena. The main research question was whether the student participants in the intervention outperformed the students in the…

This study explored secondary agriculture education as practiced by four teachers and sought to examine and describe how they interpreted and practiced the Biological Science Applications in Agriculture (BSAA) curriculum. The following questions were examined: (a) What does BSAA teaching look like in practice? (b) How do teachers perceive their…

The use of inquiry in life science can be particularly daunting because of the additional management and care living systems require. However, there are some low-maintenance organisms that work well in the classroom. One of these is the common fruit fly, "Drosophila melanogaster." Its small size, low cost, easy availability and maintenance, and…

This is an abridged version of the "Science Framework for the 2015 National Assessment of Educational Progress." The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The framework reflects the nature and…

Students learn science best with activities that mirror the way scientists work. This article describes how geologists investigate groundwater flow systems in areas of karst topography--geologic formations shaped by dissolving bedrock--and provides a way for students to replicate this research. Students also use electric current to model water…

The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The "Science Framework for the 2015 National Assessment of Educational Progress" sets forth the design of the NAEP Science Assessment. This document is…

The "Under the Mistletoe" project was developed to capitalize on student curiosity about the American Christmas Mistletoe plant and draw learners into an engaging, inquiry-based exercise that incorporates numerous life science standards and collaborative research. By collecting data on host and nonhost tree size, location, and number of mistletoe…

Even though photosynthesis is an obligatory part of the science curriculum, research has shown that students often have a poor understanding of it. The authors advocate that classroom coverage of the topic of photosynthesis should include not only its biochemical properties but also the role of photosynthesis or photosynthetic organisms in matter…

This publication presents the Nebraska Science Standards for Grades K-12. The standards are presented according to the following grades: (1) Grades K-2; (2) Grades 3-5; (3) Grades 6-8; and (4) Grades 9-12.

An instructional unit incorporating some of the Global Learning and Observation to Benefit the Environment (GLOBE) hydrology protocols provides an excellent way to connect academic learning, scientific inquiry, multiple subjects, and the values required for concerned citizenship in a democracy. This article describes the GLOBE hydrology protocols…

This article presents outdoor inquiry activities to help English Language Learner (ELL) students learn life science concepts. As a public high school ELL science teacher, the author of this article use these place-based and scaffolded inquiry activities outside to reinforce concepts she teaches in the classroom all year long. Through inductive…

Describes an inquiry appraoch in which tree growth-ring analysis is used to determine the age of a tree, trace flood history, and investigate environmental effects on tree size. (MLH)

An approach is suggested for teaching science history through inquiry training. A series of investigations are given for illustrating to students the manner in which organisms are grouped taxonomically. (SA)
