Life Cycles | Substitute Teacher
Students will explore life cycles by acting them out with simple robot-style movements and building a basic sequence of steps that shows how living things grow and change. The lesson is designed for a substitute teacher and uses easy, hands-on activities with little prep.
| Term | Definition |
|---|---|
| life cycle | The stages a living thing goes through as it grows and changes. |
| sequence | The order that events happen in. |
| stage | One part of a life cycle. |
| grow | To get bigger and change over time. |
| robot | A machine that follows directions step by step. |
Show a simple picture of a plant, butterfly, or frog. Ask: 'What do you notice?' and 'How does this living thing change as it grows?' Introduce the idea of a life cycle.
Look at the picture, share ideas, and repeat the word life cycle.
Explain that a life cycle has stages. Model one simple example, such as a butterfly: egg, caterpillar, chrysalis, butterfly. Point to each card and say the words aloud.
Repeat the stage names and help put the cards in order.
Tell students they will be 'life cycle robots.' Call out each stage and give a matching movement, such as crouch for egg, wiggle for caterpillar, still and small for chrysalis, and arms out for butterfly. Lead the class through the sequence several times.
Copy the movements in order and say the stages with the class.
Give students a simple 4-box sequence page or have them draw four boxes on paper. Ask them to draw or write the stages of one life cycle in order.
Complete the sequence page with support as needed.
Invite a few students to show their sequence or act out one life cycle for the class. Review the key words.
Share work, listen, and respond to review questions.
Ask students: 'What is a life cycle?' and 'Why is order important?' End by having the class say one life cycle together.
Answer the questions and join the closing chant.
Review the idea that all living things go through stages in a life cycle. Students do one final robot motion for the life cycle they learned and say the stage names together.
Teacher observation during the movement activity and sequence page. Check whether students can identify, order, and describe the stages of a simple life cycle.
Draw a living thing at two different stages of its life cycle and label each picture, or tell a family member the stages you learned in class.
