Life Cycles Lesson 3: Chicken & the Egg
Lesson 3 of 8
Objective: Use a model to investigate the life cycle of a bird, focusing on the unique role the egg plays in enabling the species to survive.
This lesson is on the life cycle of a bird, specifically a chicken. However, we focused only on one particular stage, the egg. Even though my students are familiar with chicken eggs, they gleaned a new appreciation for its properties by closely observing its unique function in helping the species survive.
I created a PowerPoint for this lesson,Life Cycle of a Bird, to help reach different diverse learning styles. The PowerPoint also helped guide the students through this investigation where they learned new academic vocabulary. To help them better understand these new concepts, they complete a modified Frayer Vocabulary Model. Using both of these for the lesson helped my students grapple the new content with ease.
After discussing the life cycle of the chicken, we examined the egg more closely. I had a raw chicken egg in a bowl that I placed under the document camera and I used as a "live" model to identify the parts they had just drawn in their notebooks. I also used a slide in the PowerPoint to emphasize the parts that I wanted them to specifically observe before we moved on to their "hands on" portion of the lesson where they investigate a hard boiled egg. My students removed the shell and then examined the air pocket. Next they cut open the egg to examine inside, then they had to look closely and ask each other, "What do you see?". I also had my students complete a focus page I created, Examining The Parts Of An Egg. Using this page, my students were able to work collaboratively and use the page as a guide to help them through the investigation. Here are some examples Completed Egg focus page1 and completed egg focus page 2.
Class Discussion/Wrap Up
Though this is the shortest part of the lesson, to me, this is the most important segment. We need this time to just re-group and discuss what we have learned and what we want to share. The students worked in groups of two and by giving them this opportunity they think-pair-share and express their new found ideas. This time also gives me the opportunity to further clarify some points that they may still have question about and to celebrate their successes.
