The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and…

Classroom implementation of the "Next Generation Science Standards" (NGSS Lead States 2013) does not necessarily require complete curricular overhaul. In many cases, teachers can review previously used lessons with respect to the "NGSS," evaluate alignment, and make subsequent modifications. One science activity the author has…

This article describes activities in which students sample, investigate, classify, and compare characteristics (i.e., texture, color, density, porosity) of local soils, evaluating whether the soils are healthy or at risk. Students investigate correlations between geology and geography, predict which soil types may go extinct in their state, and…

This booklet, one of six in the Living Things Science series, presents activities about diversity and classification of living things which address basic "Benchmarks" suggested by the American Association for the Advancement of Science for the Living Environment for grades 3-5. Contents include background information, vocabulary (in…

Students can use seed characteristics to discriminate between the different kinds of legumes using taxonomic classification processes of sorting and ranking, followed by construction of taxonomic keys. The application of the Learning Cycle process to taxonomic principles, hierarchical classification, and construction of keys presents the…

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

The author presents a dichotomous key to 29 tree cones, fruits, and nuts of eastern United States. Students can use the key to identify at least 10 species in a 1-hour laboratory assignment. This key uses reproductive structures that are significantly different from others. These structures are durable enough to be used in the laboratory for many…

Collecting "bugs" is an authentic, engaging approach for students to learn about various arthropods and their habitat. Students are able to construct knowledge from field notes involving direct observation, drawing, and classification of these animals. This activity has continuously provided successful measurable content outcomes in which students…

Presents a lesson that uses the learning cycle to introduce the concept of classification and the use of dichotomous keys to identify plants and animals. Encourages students to become better observers and helps them gain confidence and experience in using simple classification keys. (JRH)

Argues for an original structure for field guides, a structure that encourages induction on the part of the student and allows the student to create flexible taxa based on ecologically and evolutionary relevant field marks. Students will become more familiar with the multiple bases of taxonomy. (PR)

This book is an extensive integrated unit of study focused on that common and familiar insect--the cricket. In this edition, teachers are given a complete guide and reproducible worksheets for elementary and middle school students. With over 30 different activities on crickets, students learn science content and skills including: (1) Taxonomy; (2)…

Presents nine science activities to help students improve their thinking and problem solving skills. Activities cover the science process skills of classifying, ordering, space-time relationships, inferring, predicting, and elaborating. (MKR)

Describes the classification, number, and origin of wildflowers in North America. Discusses the use of a poster attached to the journal that includes activities to help students develop an awareness and appreciation of the native flora of North America. Additional activities are referred to in a list of 20 additional resources. (MDH)

Describes a field exercise which links ecology and taxonomy in the teaching of the species concept. Two common hedgerow plants (red and white campions) are used as a pair of "species" that are normally distinct. Plants of intermediate character can be encountered, and the status of these plants is investigated. (Author/JN)

Described is an activity which uses a 96-well reaction plate and soda straws to construct a model of the periodic table of the elements. The model illustrates the ionization energies of the various elements. Construction of the model and related concepts are discussed. (CW)
