It's a classification sensation! Demystify why we classify using an inquiry activity that helps your class sort things out. Groups begin by classifying a variety of shoes before they research organisms and design their own dichotomous...

Explore the scientific method of classification. An interactive activity asks learners to create a classification system for a group of objects and develop a flow chart to communicate their systems. In addition, individuals use a...

Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...

Part two in a series of four explores the effects of climate on succession or the changing of plant species in a forest. Groups review how to identify trees and then spend a day in the field collecting extensive data on trees to...

Budburst is the emergence of new leaves on a tree in spring. This activity requires learners to identify trees, take careful observations of their tree and note phenological dates - the date of the first leaf, first leaf falling, first...

Mammals of the ocean unite! Or not. The 20th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates how warm-blooded marine mammals survive in water. In the class activity, learners use...

Do you know the difference between a mountain lion, puma, cougar, and Texas panther? They are all the same animal but have different names in different areas of the world, which is why we use scientific names for plants and animals. The...

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local streams....

What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of Stream...
