First graders examine the life cycle of the frog, and research frogs of the Nez Perce reservation and their requirements for survival. They observe the development of frog eggs and record their observations in science journals.

Students create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...

Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.

Students study the life cycle of the frog. For this life cycle lesson set, students listen to a read aloud of Frogs, A First Discovery Book, and make a sequencing booklet that shows the four stages of the frogs life cycle. They observe...

Learners are introduced to a basic characteristic and need of living things-the ability and need to reproduce. They investigate how birds (and people) attract mates. Students discover how to build a nest. They discuss the needs and...

Students conduct hands-on experiments. In this life cycle activity, students are able to observe a variety of animals as they travel through their life cycle (brine shrimp, mealworms, frog eggs and chicken eggs). Students respond to...

Learners are introduced to the concept of life cycles. They discover how many species go through their lives in a series of stages from birth or hatching to adulthood. Such stages make up the life cycle. Students investigate the life...

Students investigate the cycle of life by observing tadpoles.  In this biology instructional activity, students utilize the Internet to read stories, observe pictures, and listen to sounds of frogs.  Students create a poster...

Students explain the different stages in the growth of a frog, then analyze and collect data to make generalizations about a larger population. They determine the survival rate of a population of tadpoles under controlled conditions.

Young scholars research Coqui frogs. Students explore the life cycle of coqui frogs and discover how these frogs have become an invasive species in Hawaii.

Second graders define and describe the characteristics of a mammal and a mammal's importance to man. They also describe the life cycle of a frog and compare and contrast a larva and an adult frog. Finally, 2nd graders study and explain...

Students research a frog's life cycle and habitat using books, the Internet and lecture. Students make origami frogs, write letters to Toad from Arnold Lobel's "Frog and Toad" and participate in a simulated camouflage activity.

Students are able to describe the reproductive cycle of the gopher frog. They are able to describe the impacts of habitat loss and degradtion on gopher frog populations. Students are explained that many factors limit the survival of...

Learners examine the early development of zebrafish as a model for embryo development in humans. They observe various stages of zebrafish reproduction from sperm and eggs to fertilized eggs and hatchlings.

Second graders describe the sequence of events in the life cycles of a butterfly, frog, and a deer. They observe the differences and similarities of parents and babies. They also discover that at different stages the animals can be...

Students observe tadpoles as they gradually change into adults.  In this amphibian biology lesson, students watch tadpoles in a tank in the classroom, keep a daily record of what they observe, and chart the growth development of the...

Students study acidic and alkaline balance. For this acid and pH levels lesson, students read information about pH, the formation of acid rain and its impact on environments. Students then complete an experiment to learn about the...

Fourth graders work in groups. They are given magazines. Students cut pictures of five mamals, five birds, five reptiles, five amphibians, and five fish. They place the pictures in a plastic bag. Students switch bags. They are explained...

Students study the basic need for animals to attract mates and reproduce young.

Fourth graders explore biology by viewing animal videos in class. For this amphibian and reptile lesson, 4th graders identify the key differences between reptiles, amphibians and other animal classifications. Students view video clips in...

Students will explore the life cycle of the Painted Lady butterfly by raising their own. They will incorporate math, science, and language arts as they graph, pattern, journal, observe, and artistically create.

Students observe the embryological development in the zebrafish. Developmental hierarchy from three germ layers is studied in depth. Research is validated on the body plan of the embryo.
