This activity is a lab where students learn to classify objects that are similar into groups and technically describe their classifications. Introduction to dichotomous keys.

Organisms are divided into each of five kingdoms based on defining characteristics. Learn about the classification kingdoms and the placement of organisms within them. [1:14:02]

This activity is an inquiry and field study based. Students will be trying to observe, document, compare, contrast, and communicate what information they were able to gather. The will use this information to make in inference about the organisms they have found and classify them as either an insect or not an insect.

Students will investigate the organization of all living things through and learn how to classify through process of classifying their own shoes. Students will complete the classification of a Jaguar and write their own pneumonic device to remember the order of biological classification. (kingdom, phylum, class, order, family, genus, species)

This activity is an interactive game that helps students learn that vertebrates are classified into five groups and that each group has common characteristics that distinguish the animal group from other respective groups.

This activity is a field collection investigation where students gather earth materials and make observations about their collection that leads them to discuss the nature of Earth surface and how it is changing.

This activity is a field investigation where students use a dichotomous key to properly identify trees in our schools nature center.

This activity is a field investigation where students explore different types of trees and identify them using leaves and classification tools.

What is it that distinguishes a living organism from a nonliving object? This video presents examples that aren't as clear-cut as one might think, enticing students to question what it means to be alive. [3:02]

An upper-level explanation of clastic sedimentary rock classification. Charts, diagrams, and review questions are included. Be sure to click on the PDF Clastic Identification key.

Click for different identification keys for igneous rocks to help you classify them correctly. Includes various color/texture keys as well as classification charts. (NOTE: At the time of writing this, the PDF links were configured incorrectly, but the files could be found through a Google search.)

Mineral photos depicting metallic and non-metallic luster. Includes shiny, glassy, and earthy examples.

This activity will help students classify objects together that are similar by one attribute. It will reveal if students understand what a pattern is and how to make one using real objects and record it with pattern block stickers.

This activity is a group activity where students investigate leaves and sort them based on established criteria.

This activity is a guided inquiry where students will find their own lichen and classify it into one of three categories. They will collect, analyze, and present their finding to the class.

What is it that distinguishes a living organism from a nonliving object? This collection of images presents examples that aren't as clear-cut as one might think, enticing students to question the meaning of life.

Chemistry is often defined as the science of matter and how it changes. This pathway introduces the composition of matter and the physical and chemical changes it can undergo.

While this 10-question multiple choice quiz is published to accompany Glencoe's Physical Science textbook, it covers the basics of matter classification taught in any course. Written in standardized test style, learners can take the quiz, find out their score, and email their results to themselves or their instructor afterward.

This activity is a classroom guided inquiry lesson where the student will sort, identify, and classify Minnesota fish.

Part of the NASA website, this is a reprint of an article in the Journal of the Royal Astronomical Society of Canada about Edwin Hubble's life and accomplishments, stressing his role in the development of modern astronomy.
