This lesson exposes children to a variety of animals and guides them through observation of animal similarities, differences, and environmental adaptations. This lesson can be used as part of a study of plants and animals. Before doing the lesson, students should know the meanings of the terms plant, animal, and living.

This resource, from the Florida Museum of , features an online article about the debate surrounding crocodilian taxonomy. One section discusses this issue in the light of the emerging trend of dropping the standard Linnean rank system for phylogenetic taxonomic rankings.

Students will come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students will examine a fictional pedigree and determine which gene is responsible for a given trait. The genetic information for individuals is depicted as a jigsaw puzzle.

This content resource builds students' knowledge and conceptual understanding about plants through interactive activities, printable worksheets, and hands-on explorations. There are six investigation cases for students to complete; each case examines a different aspect of plant life, including plant structures, life cycles and reproduction, proper environmental conditions for growth, and ecological importance. Supplemental background information and a teacher's guide with suggestions for using the materials in the classroom are also provided. A Spanish version of the web site is available.

In this lesson students will identify the plant parts involved in reproduction, identify the animal (bee) structures involved in pollination, and demonstrate how pollen moves from the male stamen to the female stigma. The lesson closes with a discussion about the benefits to both the bee and the plant in the pollination process. Note: This is the first lesson in a 3-lesson series; each lesson can be used independently.
In this lesson students will explore the links between pollination and food ...
In this lesson students will explore the links between pollination and food production. The lesson concludes with a discussion about the importance of bees in pollination. Note: This is the first lesson in a 3-lesson series; each lesson can be used independently.
In this lesson students will describe the complementary relationships between pollinators and ...
In this lesson students will describe the complementary relationships between pollinators and the plants they pollinate, and to identify adaptations that flowers have developed to encourage pollination. Note: This is the first lesson in a 3-lesson series; each lesson can be used independently.

The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

The activities in Underground Adventure guide students through an outdoor field study of soil life and some of the variables that affect soil biodiversity. Through these activities, students will gain experience in scientific skills such as hypothesis, observation, and inference. When done together as a unit of study, the activities are designed to help students answer this research question: What is the relationship between the soil's physical properties, environmental and human factors, and soil biodiversity?

In this activity students model the cycles of matter by creating an ecosystem in a jar and observing how it changes over time. Students will also research the nitrogen, water, and carbon cycles and prepare presentations to share information with their peers.
