From large to small, show your class how to organize them all! Included within the guide is everything you need to take their knowledge of classification from the cellular to the species level. The worksheets focus on building vocabulary...

No matter which way you slice it, the definition of symmetry might not be clear. The narrator of the video reflects on its true meaning as shapes, plants, and animals dance onstage for a captivated cartoon audience. Your class will be...

Check this out! Part two of a set of slide shows about biological classification; this one zooms in on kindgom plantae and kingdom animalia. Attractive and informational slides cover details that make this most appropriate for advanced...

Out of all animals, elephants alone lack the ability to jump. Scholars learn all about animals using a presentation full of fun examples. It describes different types of animals, the biological similarities and differences between...

Insects, and other invertebrates outnumber vertebrates—segmented-legs down! The first in a five-part series of videos from an Invertebrates series introduces these organisms in all their spineless glory. Each invertebrate phyla takes the...

Most animals follow a bilateral body plan. The Shape of Life series presents a short video on why this body plan survived across so many different species. The narrator explains the benefits of symmetry, stereo senses, and more....

Flatworms evolved and developed the first bilateral body plan. These hermaphroditic animals with no circulatory system star in an informative video. Scholars learn about flatworms' place in the evolutionary tree, how they hunted, and...

All humans begin as one cell and through mitosis, develop into an organism made of millions of cells, each specialized to keep people alive. The narrator of this short video explains the process by which embryos grow from a morula to a...

Comparative anatomy prevails in the lesson exploring diversity among invertebrates. Biologists examine physical characteristics of an earthworm from phylum annelida and a meal worm from phylum insecta. They also inspect a cricket and a...

Upper graders identify symmetry in nature. In this geometry lesson, pupils define the word "symmetry" and demonstrate it by folding paper. They use a worksheet embedded in the plan to find symmetry in nature.

Students analyze the similarities in different species. This lesson is part of a multi-segmented unit on the diversity of life. In this segment, students classify shoes to mimic the scientific categories of the classification system.

Learners explore symmetry. In this geometry lesson, student identify and define bilateral symmetry, radial symmetry, pentagonal symmetry, hexagonal symmetry, and cubic symmetry. Students construct examples of these types of symmetry and...

In this problem solving worksheet, 4th graders figure out how many lines of symmetry 6 Greek alphabet letters have. Students write each number and draw the line or lines on the lines provided.

Young scholars use video and the Internet to identify examples of bilateral and radial symmetry in the world around them. They create symmetrical reflection designs using pattern blocks and paper.

High schoolers reflect images and determine their symmetry.  In this reflecting images and determining their symmetry lesson, students determine if various pictures/objects have mirror or bilateral symmetry.  High schoolers reflect...

In this animal symmetry worksheet, students label organisms by the type of body symmetry that organism has. Then students draw an example of each type of symmetry. This worksheet has 3 drawings and 21 fill in the blank questions.

In this mollusks instructional activity, students will review the characteristics of the three major classes of mollusks: gastropods, bivalves, and cephalopods. This instructional activity has 17 matching, 6 short answer, 9 fill in the...

In this flatworms worksheet, students will review the characteristics of planarians, tapeworms, and flukes. This worksheet has 5 true or false, 2 short answer, and 7 matching questions.

In this animal worksheet, students determine which characteristic of an animal matches the given statement. Students describe illustrations of animals using the terms radial symmetry, bilateral symmetry, and no symmetry.

Students discuss patterns and bilateeral symmetry. In groups, they design a bilaterally symmetric pattern using fabric squares--each student in the group creating one 12x12-inch square. Then all groups put their squares into one large...

For this biology worksheet, learners label parts of a phylogenetic tree and differentiate between bilateral symmetry and radial symmetry.

Learners are introduced to the unit on the importance of diversity of life and the role that interdependence plays in our worlds. this is part of a multi-lesson unit on the diversity of life.
