This is the story of how a typical middle school lab was transformed into an open-ended inquiry experience through a few small, but very powerful, changes. By allowing students to follow their own questions, the classroom filled with enthusiasm and students learned much more about photosynthesis, respiration, and the scientific processes. The…

The National Wildlife Federation's Schoolyard Habitat (SYH) program was a partnership with AISD from 2010-2012. A total of 18 outdoor learning habitats were created on AISD elementary and middle school campuses, and a demonstration habitat was created at the AISD Science and Health Resource Center (SHRC). The purpose of the SYHs is to provide…

The process of photosynthesis is central to science curriculum at all levels. This article describes an inquiry-based laboratory investigation developed to explore the impact of light quality on photosynthesis and to connect this process to current research on harvesting solar energy, including bioenergy, artificial photosynthesis, and solar…

A formative intervention was employed to expose children to a variety of words to increase the breadth, or size of their vocabularies, and to repeatedly and supportively expose children to words to increase the depth, or semantic understanding of vocabulary. Science content words were selected since they are less likely to be included in an…

The soybean cyst nematode (SCN), "Heterodera glycines" is an obligate plant parasite that can cause devastating crop losses. To aide in the study of this pathogen, the SCN genome and the transcriptome of second stage juveniles and eggs were shotgun sequenced. A bioinformatic screen of the data revealed nine genes involved in the "de novo"…

In this study we investigated with a priming paradigm whether uni and bimanual actions presented as primes differently affected language processing. Animals' (self-moving entities) and plants' (not self-moving entities) names were used as targets. As prime we used grasping hands, presented both as static images and videos. The results showed an…

This set of inquiry lessons is adaptable for middle school through high school life science or biology classrooms and will help meet the NSTA scientific inquiry position statement (2004) and the AAAS benchmarks (1993) and NRC standards (1996; 2000) related to health and food literacy. The standards require adolescents to examine their own diet and…

Logistic growth displays an interesting pattern: It starts fast, exhibiting the rapid growth characteristic of exponential models. As time passes, it slows in response to constraints such as limited resources or reallocation of energy. The growth continues to slow until it reaches a limit, called capacity. When the growth describes a population,…

Many students enjoy biology as a qualitative science but struggle with its quantitative aspects. Yet the detection of patterns and testing hypotheses about their causes is a central aim of biological inquiry. That is the goal of the laboratory analysis described in this article. This exercise involves the students right away in collecting data…

To assist student understanding of heat transfer through woody stems, we developed an instructional package that included an Excel-based, one-dimensional simulation model and a companion instructional worksheet. Guiding undergraduate botany students to applying principles of thermodynamics to plants in nature is fraught with two main obstacles:…

Wood is transparent for microwaves and due to its anisotropic structure has anisotropic dielectric properties. A laboratory experiment that allows for the qualitative demonstration and quantitative measurements of linear dichroism and birefringence in the microwave region is presented. As the proposed experiments are based on the anisotropy (of…

In this article, the author illustrates how she shares her love of sunflowers with her kindergarten and first-grade students through an interesting art lesson. Sunflowers are easy to grow, so the author started the lesson four months earlier with inexpensive seed packets. She planted many varieties, but she most likes the colors of the Mexican…

I wrote a rap song to explain the process of photosynthesis to my students.

Every year, an elementary school celebrates different aspects of Central Texas ecology. This year, they focused on Blackland Prairie, the ecoregion on which the school is located. A schoolwide event at the end of the year offers students the opportunity to teach their parents and their peers what they've learned. The Fourth- and fifth-grade…

There is great concern by teachers, school administrators and parents regarding the increase in the number of preschool-aged students who exhibit challenging behavior in early childhood settings (Benedict, Horner & Squires 2007), need for early intervention procedures that focus on young children who may be at risk for developing patterns of…
