Label the Parts of an Egg Differentiated Activity for K-2nd Grade - Free Printable

It looks like you've uploaded an image of a worksheet titled "Label the Egg", which is designed to help students learn the parts of a bird egg. The worksheet includes three versions:

1. A version where students cut and glue labels.
2. A version where students write the labels in blank lines.
3. A third version with blank lines for labeling (possibly for handwriting practice or assessment).

Each diagram shows a cross-section of an egg, with labeled lines pointing to different parts. Below the diagrams, there's a word bank with terms:
- shell
- chorion (likely meant to be chorioallantoic membrane, but simplified here)
- yolk
- membrane
- albumen
- air pocket

Let’s go through how to correctly label the egg using scientific accuracy.

🔬 Anatomy of a Bird Egg: Key Parts

Here are the correct labels for each part of the egg shown in the diagram:

1. Shell – The hard outer layer made of calcium carbonate that protects the contents.
2. Membrane – Specifically, this refers to the inner and outer shell membranes just beneath the shell. These prevent bacteria from entering.
3. Air pocket – Also called the air cell, located at the blunt end of the egg. It forms as the egg cools after laying and provides oxygen for the developing embryo.
4. Albumen (egg white) – The clear, gelatinous substance surrounding the yolk. It provides water and protein.
5. Yolk – The yellow center of the egg. It contains nutrients and fats for the developing embryo.
6. Chalaza – Two spiral, rope-like structures that anchor the yolk in the center of the albumen.

> Note: "Chalaza" is sometimes misspelled as "cholaza" — but the correct spelling is chalaza.

✔ Correct Labeling Guide

Using the diagram:

- Outermost layer: Shell
- Just inside the shell: Membrane (shell membrane)
- At the top (blunt end): Air pocket
- Large central structure: Yolk
- Surrounding the yolk: Albumen
- Two twisted strands anchoring the yolk: Chalaza

📝 How to Use the Worksheet

#### For Version 1 (Cut & Glue):
- Students cut out the words from the word bank.
- They match each term to the correct line on the diagram.
- Glue the label next to the corresponding part.

#### For Version 2 (Write Labels):
- Students write the correct term in the blank line beside each arrow.

#### For Version 3 (Blank Lines):
- Same as above, but perhaps used for independent work or testing.

💡 Tips for Teaching

- Emphasize the function of each part (e.g., air pocket = gas exchange).
- Show real eggs or use a model to enhance understanding.
- Explain how the chalazae keep the yolk centered.

✔ Final Answer: Proper Labels

| Line Number | Part Labeled |
|------------|--------------|
| 1 | Shell |
| 2 | Membrane |
| 3 | Air pocket |
| 4 | Albumen |
| 5 | Yolk |
| 6 | Chalaza |

*(Note: The exact order depends on the diagram layout, but these are the correct terms.)*
