Ideas for a Life Cycles Unit - Learning at the Primary Pond

Ideas for a Life Cycles Unit

Hi from Antarctica the midwest!  I am currently looking out my window at the heaps of snow that came down this weekend, and thinking about how ready I am for spring.  And speaking of spring, I love teaching my life cycles unit in the spring!  I thought I’d share some of my favorite resources in case you are planning ahead (make sure to read to the end because I have a big list of free web resources for you)!

When I teach life cycles, I like to teach the butterfly, frog, chicken, and plant life cycles one after the other.  I encourage the kids to make connections between the different life cycles so that they understand the “big idea” that all living things grow and change.  I start off the unit by having the kids each bring in a baby photo.  I collect them all, spread them out on the tables, and have the kids rotate through the tables like centers.  They try to guess whose baby picture belongs to who!  After we finish the baby pictures activity, we talk about how they have grown and changed since they were babies…both physically and in their abilities to do “big kid” stuff.  Soon after that lesson, we talk about the difference between living and nonliving, and I explain that we are going to be learning about how living things grow and change.  


The next day, I launch into teaching about the butterfly life cycle.  I read The Very Hungry Caterpillar during the first lesson, since most of them have already heard it and already know what happens at the end.  We focus on the butterfly life cycle for about 2 weeks, during which they learn lots of vocabulary, including the body parts of an insect.  Here are just a few of the learning activities and crafts that we do as part of this mini-unit:
My students write down their observations about our classroom butterflies in this journal! I also give them the vocabulary cards to support them with the academic vocabulary.Butterfly Life Cycle Observation Journals 

(The kids use these with the butterflies we have in our classroom and use the vocabulary cards shown above the journal to support their writing)

Give students this template and have them use q-tips to paint one side. When they fold over the paper, they see the symmetry of a butterfly's wings!

(I have the kids use tempera paint and q-tips to design one side, then fold and see what happens to the other side – read more about how to do this craft HERE)
 
Kids love putting together these butterfly vocabulary puzzles as a center! They can also use the puzzles to write about the butterfly life cycle.Butterfly Life Cycle Vocabulary Puzzles
 
I integrate our science unit on life cycles into guided reading with these butterfly life cycle leveled texts!

After the butterfly life cycle mini unit is over, we move on to the frog life cycle!  One of my favorite things we do during this part of the unit is to make the frog life cycle out of playdough.  I wish I had some photos of this – the kids get really into it!  You can have them work in partners to get them using the vocabulary while they talk about how to make each stage in the life cycle.  Here are a couple of the other activities that we do during this part of the unit:
 
My Kindergarten and first grade students put together these frog life cycle puzzles and then explain the frog life cycle to a partner!

We use these venn diagrams during our life cycles unit to compare the body parts of a frog and tadpole.

We always sing this so-cute song called “Tadpole Blues” by Peter Combe.  
 
Okay, so after the frog life cycle part is done, we move on to the chicken life cycle (if I time things right and the holiday doesn’t fall too late, we do this right around Easter!).
 
I have my Kindergarten and first grade students do this chicken life cycle cut-and-paste activity around Easter! It's also perfect for a life cycles unit or chicks in the classroom.
Chicken Life Cycle Cut and Paste
(As with all the other life cycles, we do cut-and-paste practice – and I have the kids write labels for each picture when they’re finished)
 
Students sort these animal pictures to show whether they are oviparous or viviparous animals!
Oviparous vs. Viviparous Picture Sort
(Once we’ve learned about the chicken life cycle, we learn about other animals that come from an egg, as well as the terms “viviparous” and “oviparous”)
 
And last but not least, after the chicken life cycle mini-unit is finished, we move on to the life cycle of a plant (I also hit on plant parts here, too.)   
Have students color in the picture and label the parts of a plant!

 To wrap up the whole unit, we do some comparing and contrasting of the different life cycles, and the kids do a final project to demonstrate their learning.  
 
All of the materials shown are found in this bundle:
 
Life Cycles Bundle for Chicken, Butterfly, Frog, and Plant Life Cycles
 
It’s cheaper to buy the bundle, but you can also purchase the units individually:
