Science 2: Life Cycles

This is an amazing time-lapse, close-up video (saved without ads) of bees going through their hatching process.

In their life cycles, hermit crabs have to change their shells several times. They actually line up with other crabs to do it!

Frogs have one of the most fascinating life cycles! Baby tadpoles look nothing like frogs. How do they change so much?

Watch this slideshow of images and descriptions of the stages of the butterfly life cycle, from egg to caterpillar to butterfly.

Every butterfly you've ever seen was at one time, early in its life, a very hungry caterpillar. Frogs, too, go through life stages during which they look nothing like the leggy creatures they ultimately become.

Every animal's life goes through the same cycle: birth, growth, maturity, reproduction, and finally, death. Learn about each cycle here!

Watch this video to learn about the two kinds of angiosperms. You'll learn the characteristics of monocots and dicots.

Watch this video to learn more about the different parts of flowers and how each part does a certain job. Take the quiz after you watch the video.

Learn about the different types of gymnosperms and their distinctive features. There is a quiz to test yourself after the slide show.

Check out this slide show with magnified images of plant cells. If you're interested, you can try the karaoke song and the quiz.

This slide show has images of two types of plants without seeds: vascular and non-vascular. Test yourself with the quiz after you've reviewed the slide show.

This slideshow of images describes the jobs that the roots and stems have to keep a plant healthy. There's a quiz to test your learning.

Today, we’ll find out what botanists study and how knowledge of plants can help you navigate everyday life. Along the way, we’ll uncover plants’ pervasive, civilization-shaping power—and find that they have their own ways of communicating.

In this lesson, students will learn how plants take water out of the environment.

In this short educational video, you're going to learn all about the stages of a plant's life cycle.

Join Ms Tree as she walks down memory lane through the stages of the plant cycle, to see how she transformed from a seed to a beautiful plant that bears fruits.

Plants are all around you! You walk on them, eat them, and even climb them. Did you know you can grow them too?

Jessi and Squeaks show you how a tiny seed - like the kind you plant in your garden or even eat in your trail mix - grows into a big plant!

Squeaks and Mister Brown want to learn all about how the tiny little seeds they'll plant in the ground will grow into vegetables they can eat!

This document provides teachers with sample instructional activities, assessments, and resources to support teaching Science Grade 2 (Living Systems).

This lesson deepens students' understanding of the similarities and differences in the life cycles of organisms.

Students listen to a read-aloud of the Eric Carle picture book The Very Hungry Caterpillar. Then they watch a time-lapse video of the monarch butterfly life cycle and create their own picture books.

In this lesson, students explore and compare chicken and butterfly life cycles through the development of scientific drawings or models.
