Biodiversity Patterns is a Grade 6 Science worksheet resource focused on Biological Evolution: Unity and Diversity, with an emphasis on how species distributions and community patterns can be studied. The resource is identified with the NGSS framework and gives students structured practice with biodiversity vocabulary, evidence, and ecological patterns.

Explore Biodiversity Patterns

Students examine species occurrence, species richness, island faunas, latitudinal gradients, habitat heterogeneity, turnover, community composition, colonization, habitat fragmentation, and endemism. The reading passage introduces how scientists use records and surveys to examine changes in communities and interpret patterns in where species occur.

Student Practice

The worksheet combines several ways for students to work with the concepts. Students read a focused passage, answer multiple-choice questions, evaluate true-or-false statements, write short-answer responses, interpret a labeled diagram, complete a categorization activity, and review concise student notes. Questions address both vocabulary and application, including how colonization can add species to an area, how habitat fragmentation can change species distributions, and what endemism means.

Teacher-Ready Support

The resource includes student notes at the bottom of the worksheet. The Answer Key PDF also includes a Teacher Guide with learning objectives, teaching tips, discussion questions, and common mistakes. This gives teachers additional support for introducing the topic, guiding classroom discussion, and addressing misconceptions about biodiversity patterns.

Classroom Use

Use this biodiversity worksheet for science instruction, guided practice, independent work, review, or assessment. The content provides opportunities for students to connect species richness and occurrence with real ecological patterns while considering how historical records, surveys, colonization, habitat fragmentation, and endemic species contribute to understanding biodiversity distributions.

This resource is especially useful when teaching students to describe biodiversity using specific scientific vocabulary and to connect observations of species and habitats with broader patterns in ecological communities.
