Image/Photograph

Frog life cycle:

This resource shows each stage in the life cycle of a frog. The life cycle of a frog includes the egg stage, tadpole stage, froglet stage, and adult frog stage. Tadpoles live in water and use gills to breathe. They develop lungs as they mature into frogs and live on land.

Lesson Plans

A Whale's Tale:

 

 This lesson covers:

  • A humpback whale’s basic needs and how they are similar to humans
  • A humpback whale’s feeding habits and social behaviors
  • Threats to humpback whales and how scientists work to protect them

Type: Lesson Plan

Juvenile Tarpon Reading:

Students will learn about tarpon life cycles and the many different habitats and resources these fish need as they grow. They will create postcards as “tarpon” in different life stages, explaining what their life is like at that point in their life cycle.

Type: Lesson Plan

Tarpon Lesson Plan:

Students will learn how body shape and fin placements make tarpon efficient swimmers and leapers that are well adapted to their environments. They will complete exercises that help them understand the function of each fin, and they will create their own paper tarpon.

The Perils of a Plant: Watering Can - An Engineering Design Challenge:

This Engineering Design Challenge is intended to help students apply the concepts of life cycles, the understanding that all living things have basic needs, a knowledge of habitats and practice working with money as they build and experiment with containers to meet the water needs of bean plants in all stages of their life cycle. It is not intended as an initial introduction to these concepts.

Type: Lesson Plan

Tadpole Habitat - An Engineering Design Challenge:

This engineering design challenge is intended to help students apply the concepts of life cycles, the understanding that all living things have basic needs, build on their knowledge of habitats, and practice working with money as they build structures to meet the needs of a tadpole. It is not intended as an initial introduction to these concepts.

Type: Lesson Plan

Sprout Snacks:

This lesson integrates text features from reading into science with the study of plant parts. Students will listen to a story, watch a short video and design their ideal plant while being able to recognize the various parts of all plants.

Insects Everywhere!:

This resource was completed on a general lesson plan template, but also includes the 5E lesson model. It is an interactive lesson that includes an outdoor exploration. If you do not have the ability of taking your students outdoors you can complete the lesson by having an ant farm in the classroom available for student observations.

Type: Lesson Plan

Hatching Chickens:

This lesson will help students understand the importance of carefully observing and caring for eggs and chickens in the classroom.

Type: Lesson Plan

Butterfly Life Cycle:

In this lesson, students will explore the life cycle of the butterfly through different centers and observation of a living butterfly going through its life cycle.

Type: Lesson Plan

The Plant Life Cycle (using lima beans):

In this lesson, students observe the life cycle of a lima bean.

Type: Lesson Plan

Exploring Plants:

Students will be introduced to the study of plants in this lesson. First they will sprout bean seeds on moistened paper towels, then make drawings and measurements of their growth. They will watch time-lapse videos that illustrate a plant's major growth stages. Another clip covers fruits and asks students to consider how their seeds are spread. They will gather seeds by walking outside with an old sock over one of their shoes, then plant their sock to observe the resulting plants.

Type: Lesson Plan

Life Cycles of Frogs, Dragonflies, and Butterflies:

This lesson can be used to extend students' understanding of the life cycles of organisms by comparing and contrasting them. Eric Carle's The Very Hungry Caterpillar will be read first, then students will watch a video that studies the developmental stages of frogs, dragonflies, and butterflies. Insect and frog life cycles will be compared to one another, then they will be compared to the stages of human development.

Teaching Ideas

The Study of Life Cycles:

This teaching idea overviews a project by second grade students who studied life cycles of insects and created a book with illustrations about insects. Each entry contained descriptive information about the insects being studied- including habitat, life cycle, diet, behavior, predators, and interesting facts.

Type: Teaching Idea

Plant Life Cycle:

Students learn about the life cycle of plants by watching a time-lapse video, providing students with further evidence that all living things grow and change throughout the life cycle. There are also two optional video clips that show students how to set up a germination experiment, and how to collect seeds with socks and grow plants from them.

Type: Teaching Idea

Life Cycle of a Butterfly:

Students learn about the life cycle of a butterfly.
