Honeybees, butterflies, and ladybugs all have fascinating mutually beneficial relationships with plants and play important ecosystem roles. Children also love these creatures. But how do we teach children about these symbiotic interactions and help them appreciate their vital roles in our environment? One must is to give children direct experience…

In elementary and secondary classrooms, educators use plants for various reasons. Plants are often used during learning activities and science experiments. Also, educators frequently decorate their classrooms with plants to make the room more inviting and comfortable. Few new educators have been informed of the potential hazards of commonly known…

In this article, the author describes a gourd art project for her art club. Prior to students actually working on the gourds, the author and her art volunteer did a joint demonstration on the process students would go through to create their project. The volunteer brought in and explained her gourd art and shared information about the drying and…

We have developed experiments and materials to model human genetics using rapid cycling "Brassica rapa", also known as Fast Plants. Because of their self-incompatibility for pollination and the genetic diversity within strains, "B. rapa" can serve as a relevant model for human genetics in teaching laboratory experiments. The experiment presented…

For curriculum content-related reasons, inquiry activities can be difficult in classrooms unless the activities are approached in a manner that makes variations among student group findings understandable in the context of the study. Studies of individual animals and plant reactions to stimuli, such as insect exploratory behavior, allow the…

The biological processes of photosynthesis and plant cellular respiration include multiple biochemical steps, occur simultaneously within plant cells, and share common molecular components. Yet, learners often compartmentalize functions and specialization of cell organelles relevant to these two processes, without considering the interconnections…

This inquiry-based lesson was inspired by Denise Fleming's book entitled, "In the Tall, Tall Grass" (1991). The author used the book and a real study of prairie grasses to teach kindergartners how to make careful observations and record what they see. In addition, they learn how to "draw as scientists." Here the author describes her class's yearly…

Case studies have been used in undergraduate science education as a way to develop students' critical thinking and problem-solving skills. However, little empirical evidence exists on whether this teaching method is having the desired impact on students in plant pathology courses. This study evaluated the influence of the case teaching method on…

The Human Exploration Project (HEP) units have several common characteristics. All units: (1) Are based upon the Technological Literacy standards (ITEA, 2000/2002); (2) Coordinate with Science (AAAS, 1993) and Mathematics standards (NCTM, 2000); (3) Utilize a standards-based development approach (ITEA, 2005); (4) Stand alone and coordinate with…

Enrollment by students in degree programs other than traditional horticulture, agronomy, and soil science has increased in basic plant and soil science courses. In order to broaden the appeal of these courses to students from majors other than agriculture, we developed a hands-on laboratory exercise relating the basic concepts of a soil energy…

Phylogenetic trees, which are depictions of the inferred evolutionary relationships among a set of species, now permeate almost all branches of biology and are appearing in increasing numbers in biology textbooks. While few state standards explicitly require knowledge of phylogenetics, most require some knowledge of evolutionary biology, and many…

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…

The authors show how teachers can use nature explorations as a personal guide in implementing early learning standards. They describe five outdoor experiences of children in age groups ranging from 20 months to 5 years. A chart specifies which of the Nebraska state learning guidelines and Creative Curriculum goals the experiences meet, across the…

An HPLC undergraduate experiment on the analysis of traditional Chinese medicine (TCM) has been developed. Two commonly used herbs ("glycyrrhizae radix" and "cinnamomi ramulus") are studied. Glycyrrhizin, cinnamic acid, and cinnamaldehyde are chosen as markers for the herbs. The dried herbs in their natural state and a TCM…
