Purpose & Task Overview
This activity will help develop your spatial reasoning skills. You will read a text that describes an object with a variety of components but does not describe them in any particular order. To develop your spatial reasoning ability, you will engage in the following tasks:

1. Locate the spatial signals that tell you where the components are.
2. Identify the spatial signals that communicate each component’s relationship to the others.
3. Based on those physical relationships, choose a logical spatial order in which to describe the components.
4. Using the spatial order you chose and using your own words, rewrite the text to describe the components logically, accurately, and clearly.
5. You may work directly on this assignment or create a new document – just make sure you save your final work as a .PDF before uploading it to Bb,

Part 1: Locate the spatial signal words
Read the text below and use a pencil or highlighter to locate signal words that describe the physical characteristics of the components.
Look for and note both physical and spatial descriptions, especially when the passage explains the relationships of components to each other.

The components of a chicken egg 

1. The white of an egg is known as the albumen, which comes from albus, the Latin word for “white.” Four alternating layers of thick and thin albumen contain approximately 40 different proteins, the main components of the egg white in addition to water. Opaque ropes of egg white called chalazae hold the yolk in the center of the egg. Like little anchors, they attach the egg yolk’s casing to the inner membrane lining the eggshell. The more prominent they are, the fresher the egg.

2. The shell of an egg is covered with as many as 17,000 tiny pores. Eggshell is made almost entirely of calcium carbonate (CaCO₃) crystals. It is a semi-permeable membrane (air and moisture can pass through its pores). The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust.

3. Lying between the eggshell and egg white are two membranes, the outer and inner membranes. These two transparent protein membranes provide efficient defense against bacterial invasion. They are incredibly strong, made partly of keratin, a protein that’s also in human hair. The clear casing that encloses the yolk is called the vitelline membrane. The yolk contains less water and more protein than the white, some fat, and most of the vitamins and minerals of the egg. These include iron, vitamin A, vitamin D, phosphorus, calcium, thiamine, and riboflavin. The yolk is also a source of lecithin, an effective emulsifier. Yolk color ranges from just a hint of yellow to a magnificent deep orange, according to the feed and breed of the hen.

4. An air space forms when the contents of the egg cool and contract after the egg is laid. The air cell usually rests between the outer and inner membranes at the egg’s larger end, and it accounts for the crater you often see at the end of a hard-boiled egg. The air cell grows larger as an egg ages.

Part 2: Identify the spatial signal words

List the words or phrases that function as spatial signals that communicate the location of each component in relation to the others.

Part 3: Choose a logical spatial order

Which spatial order would be the most logical to describe the components of a chicken egg?

• front to back/back to front
• inside to outside/outside to inside
• top to bottom/bottom to top

State your choice and explain why you believe it to be the most logical:

Now, fill in the two columns of the table below using the same spatial order you just chose to fill in the right-hand column. You may add in rows as you need them.

Part 4: Paraphrase a spatial description

Write one paraphrased paragraph that follows the guidelines below:

• Use the spatial order you decided on in Part 3.
• Focus only on the components of the egg and include all of them.
• You may have to briefly describe a component’s function but maintain a spatial focus on each component’s location.
• Use spatial signal words to communicate each component’s physical relationship to the others.
• Exclude information that isn’t directly related to a component’s location or function.
• Single-space your paragraph and use an accessible font like Calibri or Arial.
