Students analyze relationships about animals and create a model of classifications based on both the similarities and the differences. They also discuss a dichotomous key before they create a cladograph using different types of candy.

Students analyze the complexity of organism classifications based on certain criteria.  In this classifying organisms lesson students study taxonomy and gather information and leaves to do their own experiment on classification. 

Students investigate various tree leaves and use a dichotomous key to classify the leaves. In this leaf classification lesson, students study various types of leaves and their Genus. Students record observations for each Genus.

Three lessons and five assessments are contained in this material. Various paper shapes are sorted as a simulation of biological classification. Learners gather a list of living things that they are familiar with and design a...

Young scholars are introduced to the five kingdoms and discover why there is a need for a classification system. Using the internet, they examine how scientific names are created and practice putting animals into their correct...

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 examine how the method of classification is used. In this sorting lesson plan students take a pre-test, classify organisms and complete a crossword puzzle.

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

In this biodiversity worksheet, students determine the relationship and complete the evolutionary tree for the plants listed. Students review genetic code and DNA sequencing. This worksheet has 1 graphic organizer, 8 multiple choice, and...

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...

Learners explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this lesson.

Students, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.

Students observe their local forest and document the change that occurs over the school year.  For this forestry lesson, students utilize a GPS to mark a certain area of the woods as their study area for the remainder of the year....

Fourth graders study the uniquely diverse structural design of leaves and demonstrate knowledge of interdependence between structure and environment through research, laboratory activity and written summary.

Students examine termites and their trail-marking behaviors. They draw lines on paper with various ink pens and experiment to see which types of ink the termites follow--or which inks do and do not elicit trail marking behavior.

Learners explore basic methods of GPS data collection, uploading the data to a computer, and making simple maps of their data using GIS software. They create a map of the data using GIS software (or Excel)

Using their own classification methods students will identify the types of trees found around their school and neighborhoods. Students will then present their classification methods to the class. Later students will use dichotomous tree...

An outdoor lab where students investigate the environment and decide a method of survey to identify trees in their area. To finish the exercise they will create a dichotomous key of the ten they identified.
