Students read an article on the characteristics of wolves and dogs then complete a phylogenetic tree of the canid family. They then write an essay justifying why or why not wolves and dogs should be classified as different species.

First graders investigate objects using rulers and magnifying glasses. They record their observations using a data-recording sheet and write a characteristic for each item they observe. They use the ruler to solve math problems.

Students create a flip book that describes the basic characteristics of the five main animal kingdoms. They research the animal kingdoms, include examples of organisms for each kingdom and illustrate the finished text.

Students observe and classify objects that float or sink.

Students examine the definition of species. Students complete a phylogentic tree of the Canidae family. They write an essay justifying why or why not wolves and dogs should be classified as different species.

Young scholars identify characteristics of birds, name several species, and explain how birds fly. They make nests and give bird presentations.

First graders compare and contrast adult and baby animals to identify similar characteristics shared by both.

Pupils examine the characteristics of the peregrine falcon. They investigate endangered and extinct species, and how the environment affects the process.

Students describe objects using only their sense of touch. For this lesson on describing characteristics, students use only their sense of touch to describe an unseen object in a box. This lesson can be used an an introduction to plant...

Students study about the survival and hunting strategies of several different kinds of spiders. They also be introduced to scientific classification of spiders and write a brief report about one of the spider families they observe.

Third graders classify and sort different types of beans to be introduced to the classification system in science. As a class, they identify the characteristics of living and non-living organisms and make a chart in their journal to ...

Fifth graders define words. They create a dichotomous key. After carefully examining pill bugs, 5th graders record observations. They compare and contrast habitats of pillbugs.

Pupils investigate the concept of evolution and how natural selection is used as an indicator that evolution has happened. They recognize the three effects it has on diversity and how adaptations can develop. Diversity is explained as...

Students examine how animals protect themselves from predators and camouflage themselves. They participate in a simulation in which they locate red and green yarn "caterpillars," organize their data, and generate a bar graph using...

Students explore the concept of linear regression. In this linear regression lesson, students find the line of best fit for a set of data pertaining to a frog population. Students use their line of best fit to predict the frog population...

Fourth graders are divided into small groups and collect 4 objects from the playground. They take 5 to 10 minutes to classify their groups and discuss their findings including the terms "living" and "non-living". As a class they discuss...

Learners explore limu diversity. In this ocean ecosystem lesson, students classify limu according to its physical properties. Learners work in small groups to generate scientific observations and sort limu by characteristics.

Students investigate seasons. In this environment instructional activity, students describe the four seasons by drawing an appropriate tree for each season.

Students develop a classification scheme based on the structural features of organisms.  In this organism lesson students divide into teams and complete a fun activity. 

Students apply the scientific method to identify rocks from glacial deposits, hypothesize how they got there and then test their hypothesis. They are given the experience of active, hands-on inquiry.

In this bluebirds project instructional activity, students are given directions on completing a project about bluebirds including measurements, scientific method questions, data entry, and more. Students complete 15 exercises.

Fourth graders observe, plan, research, and create a field guide for the trees that are in their schoolyard. In this trees lesson plan, 4th graders make careful observations of what they see around their school and create a guide.

For this science worksheet, students read the facts sheet for the buffalo. They could use this for a class activity for classifying animals.

Middle schoolers create a dichotomous key to different varieties of potato chips. In small groups, they observe and record characteristics of the potato chips to use in the key. They switch keys with another group to see if they can...
