Students act as a taxonomist and, given a certain situation, classify existing organisms.

Students view video clips and observe similarities and differences between animals. They sort animals into groups for a zoo. They make a graph of their observations and review scientific classifications.

Learners study the major phyla of the animal kingdom. In this biology lesson unit, students identify their general characteristics. They define taxonomy terminologies.

Fifth graders observe several examples of types of rock and write about their similarities and differences in their science journals. They discuss their observations and discover that rocks are grouped according to the scientific...

In this amines instructional activity, students solve 7 problems including classifying given structures, ranking them based on their boiling point, and naming structures.

Students become familiar with the structure and use of dichotomus keys. They demonstrate a comprehension of the fundamental principles of taxonomy by classifying organisms from a local ecosystem. Students are introduced to the term...

Students use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...

Students classify, weight and organize items during this lesson. This lesson works great as or with an introduction of the Periodic Table of Elements.

In this rock cycle worksheet, students copy the table illustrated for data and observations of rock samples. Then they examine the rock samples observing the characteristics and the arrangement of grains in each. Students then record...

Students view a cloud slide show presentation and identify types of clouds. They estimate height based on cloud's appearance. They discuss the vague nature of cloud nomenclature and compare it to the English standard measurement system.

Second graders identify different types of animals on a two charts titled "Mammals" and "Not Mammals." They listen as the book, "They Call Me Wooly," by Keith DuQuette is read to them. Students are asked what is different about the...

Students discuss what makes a living thing (for example, cellular respiration) and collect a selection of living things from outside. They divide their organisms into plants and animals and create a key for the divisions.

This animal science PowerPoint introduces various types of animals that live in groups. The slides contain real photographs along with explanations of why animals live in groups and what their roles are.

Students classify leaves by shape and margins and use them to create models of plant fossils. By using paper over a leaf, they simulate fossilization of organisms onto sedimentary rocks. Following instructions on worksheets, students...

Students participate in various outdoor science activities to enhance their observation, classification, and analysis skills. In this outdoor lesson, students begin by observing a tree from a straightforward angle, then from the...

Students gain an understanding of the science of taxonomy and how it is used in classifications. They use an identification key and construct a key of their own. They identify tagged trees on the school property with their lab group...

In this biology instructional activity, students identify and locate various vocabulary terms relating to the classification of living things. There are 28 biology terms located in the word search.

Crabs and lobsters ... yum! The 18th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on invertebrate marine life. After the lecture slideshow, learners conduct an activity to sample...

Explore the finer details of primate skulls with these puzzles, incorporating advanced scientific analysis of two suborders- Prosimians and Anthropoidea- and one superfamily- Hominoidea. Learners read about the unique characteristics of...

After years of war and unrest, how quickly will nature recover? Started as a project to track lion populations, WildCam Gorongosa now tracks many species. Through hidden camera evidence, scientists know species are returning to the area....

I spy a spine. The 19th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explores vertebrate species, such as sharks and other fish. Learners take part in an activity evaluating the...

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...

Acid rain, and how it affects the environment, is the focus of this Earth science lesson. During the study, learners evaluate measures to reduce acid rain, and design an investigation to demonstrate the conection between a hypothesis and...
