Students compare and contrast hair sheep and wool sheep, discover the reasons why farmers raise sheep, and explore ways farmers meet the needs of the sheep they raise. Grades K-2

breed: a group of animals or plants within a species having a distinctive appearance and typically having been developed by deliberate selection

parasite: an animal or plant that lives in or on another animal or plant in order to get food and protection

shear: cut the wool off

wool: the fine, soft, curly or wavy hair forming the coat of a sheep, goat, or similar animal used in making cloth or yarn

There are different types or breeds of sheep. Some sheep, such as Dorset, are wool sheep raised for their wool, meat, and/or milk. Wool sheep grow thick wool that needs to be sheared because they do not naturally shed. The wool fiber is used to make yarn, fabric, carpets, and upholstery. Some sheep, such as Katahdin, are hair sheep. They mainly grow hair that sheds naturally and do not need to be sheared. Hair sheep are raised for their meat and milk. Their hair is not suitable for spinning or felting.

The hair sheep breeds make up a little more than 10% of the world's sheep population.¹ Hair sheep have a resistance to internal parasites, are fairly tolerant to heat, are good breeders, and forage on weeds and plants that wool sheep and cattle avoid. Hair sheep are not suitable for competitive market lamb shows because they are smaller than most wool sheep and do not produce as much meat per ewe.² Many view hair sheep to be less attractive than wool sheep. Bred for hot, humid climates, hair sheep tend to not do as well in cold weather as wool sheep.

A common misconception is that hair sheep are a cross between breeds of goats and sheep. This is not true. The primary difference between hair and wool sheep is the ratio of hair to wool fibers. Although both have some hair and wool, hair sheep have more hair and wool sheep have more wool fibers.

1. Show the students pictures of a wool sheep and a hair sheep.
2. Ask the students to compare and contrast the wool sheep and the hair sheep. Use a Venn diagram to list the similarities and differences. You may need to guide the students to look closely at the coat of the sheep.
3. Explain to the students that they will explore the differences between wool sheep and hair sheep.

1. Read Farm Animals: Sheep by Cecilia Minden.
2. Refer back to the Venn diagram and the two sheep pictures from the Engage section of this lesson. Lead a class discussion about wool and hair sheep. Include the following points in the discussion:
   • Most sheep have wool that needs to be sheared or cut off to keep the sheep cool. They are called wool sheep.
   • Some sheep have hair, which does not need to be sheared because the sheep shed naturally. They are called hair sheep.
   • Some farmers choose to raise hair sheep because they do not need to be sheared.
3. Ask the students, "What can wool sheep provide for us?" (wool for clothes, meat, and sheep milk for cheese) "What can hair sheep provide for us?" (meat and sheep milk for cheese) Explain to the students that hair sheep's hair sheds just like a dog sheds its hair. The hair is not used for yarn or fabric because it is different than wool fibers.
4. Allow time for the students to make changes or additions to their Venn diagram using the information from the book or class discussion.
5. Ask the students, "What do sheep need to survive?" (food, water, shelter, and air just like humans) Add this information to the Venn diagram. Explain to the students that wool sheep and hair sheep both have the same needs. Sheep eat grass, hay, and grains.
6. Have the students use the Agriculture Graphic Organizer Sheep Retell page to tell or write what they learned about wool sheep and hair sheep.

After conducting these activities, review and summarize the following key concepts:

• There are different breeds of sheep that are raised for their wool, meat, and/or milk.
• Wool sheep grow thick wool that needs to be sheared because they do not naturally shed.
• Hair sheep grow hair that sheds naturally and do not need to be sheared.
• Wool sheep and hair sheep both have some wool and some hair. Wool sheep have more wool fibers and hair sheep have more hair.
