Students draw comparisons between organisms. They classify organisms. Students are introduced to dichotomous keys and how to create and use a dichotomous key to identify a variety of objects. They begin by defining classification, and...

Young scholars review the classification system for living organisms and apply it the classification of insects and flowers in the still life by Ambrosius Bosschaert. They create a chart classifying the animals and plants in the painting...

Learners create a collage. In this animal classification lesson, students discuss why and how scientists classify animals. Learners view pictures of different animals and decide which class each animal belongs to. Students compare...

Students classify and record objects they find "underground." In this observation lesson, students dig into bins filled with soil and encounter various objects such as bark, twigs, etc. Students classify their findings.

Students observe the structures of skulls as presented in drawings, and determine which are most closely related to the skull of the mosasaur.

Students minerals and how they form. They investigate the classification of minerals according to physical properties. Students watch a video about mineral characteristics. In groups, students participate in hands-on activities and...

Learners identify tree species by their leaf characteristics. In this dendrology lesson, students learn leaf vocabulary and collect leaves. They identify the leaves using the leaf characteristics and the vocabulary that they learned.

Students examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino acid...

Students participate in an interactive game to review how living things are classified.

For this species worksheet, students use a dichotomous key to identify the 8 different species of "Norns," a fictitious animal group.

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

Learners are assigned to bring five flowers. They explore flowers to distinguish different physical features of flowers. They compare and contrast different flowers to determine what features they have in common. Students develop an...

This animals PowerPoint provides a race car game in which students answer a variety of questions about animals, the majority of which are based on ways in which animals adapt  to their surroundings and behave to survive.

Students learn and practice identifying Earth's minerals and their properties. Working in small groups, they evaluate minerals. This is a well-described lesson, which students enjoy.

Young scholars collect and analyze pollen from different species of plants. In small groups, they classify pollen according to shape, size and physical characteristics. They draw the basic anatomy of flowering plants and create a...

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 use their senses to record and collect data. In How Do I Classify Things in My World?, students practice classifying objects as living or nonliving. In Is it Real Or Pretend?, students group objects as real or pretend. In What...

Fourth graders provide a habitat for live mealworms and observe their life cycle. In this animal life cycle and scientific inquiry lesson, 4th graders create a habitat for a live mealworm and observe and record related data as it grows....

Students explore natural selection and its influence on the populations to fine tune traits and characteristics. The acquisition of traits developed out of need is examined through a game played in class.

Learners examine how plants are able to adapt to their ecosystem and the role that fire plays in changes through the years.  In this ecosystem lesson plan students complete several exercises focussing on plants and their adaptations...

Eleventh graders identify the parts of an ecosystem and how communities change over time.  In this ecology lesson students formulate a habitat restoration plan.

Young scholars explore vermicomposting, the species of worms needed and the proper climate for it.  In this composting lesson students make their own worm compost bin. 

Students examine the different species that are headed towards extinction.  In this animal population lesson plan students compare the causes of extinction, research an endangered species and present an oral report. 

Fifth graders identify the species of plants and animals found in an environment. They compare these findings to plant and animal species found in an unlike environment. Students acquire and compare soil samples from the two sites chosen.
