Hands-on learning is a highly effective teaching method for topics in STEM disciplines. Unfortunately, environmental science teachers sometimes lack the tools to engage their students in hands-on experimentation in real-world research outside of the classroom. Partnerships between science professionals and teachers can help address this disparity, and operating within an established community science program is an excellent way for teachers and professionals to provide K–12 students opportunities for involvement in real-world research. We developed a four-stage program that maximizes the benefits of bringing together members of the professional and academic sectors; the stages include Learn, Collect, Report, and Communicate (LCRC). The goal of this program is to bring science professionals into a K–12 classroom to emphasize the importance of conducting research using the scientific method, to promote responsible community science, improve students' data literacy and critical thinking skills, and highlight the relevance of science communication. We demonstrate this program with a case study using water quality research in high school AP classes. Evaluations of the case study indicate this framework, and the engagement with science professionals alters students' perceptions of science and scientists while giving them the skills, knowledge, and confidence to pursue scientific endeavors.

The benefits and costs of varying container sizes have yet to be fully evaluated to determine which container size affords the most advantageous opportunity for consumers. To determine value of the tree following transplant, clonal replicates of Vitex agnus-castus L. [Chaste Tree], Acer rubrum L. var. drummondii (Hook. & Arn. ex Nutt.) Sarg. [Drummond Red Maple], and Taxodium distichum (L.) Rich. [Baldcypress] were grown under common conditions in each of five container sizes 3.5, 11.7, 23.3, 97.8 or 175.0 L, respectively (#1, 3, 7, 25 or 45). In June 2013, six trees of each container size and species were transplanted to a sandy clay loam field in College Station, Texas. To determine the increase in value over a two-year post-transplant period, height and caliper measurements were taken at the end of nursery production and again at the end of the second growing season in the field, October 2014. Utilizing industry standards, initial costs of materials and labor were then compared with the size of trees after two years. Replacement cost analysis after two growing seasons indicated a greater increase in value for 11.7 and 23.3 L trees compared to losses in value for some 175.0 L trees. In comparison with trees from larger containers, trees from smaller size containers experienced shorter establishment times and increased growth rates, thus creating a quicker return on investment for trees transplanted from the smaller container sizes.
