3. Lesson 10.1 Tongue Students will describe characteristics of the tongue and identify its functions and parts.

4. The Tongue God designed the tongue to do several things. • It assists in the formation of sounds, making our speech intelligible to others. • It helps us chew and swallow by holding food and moving in around in the mouth. • It contains tiny structures called taste buds that allow us to taste.

5. The tongue is made up of many groups of muscles • that a person can control. • The tongue can move in many directions. • The tip of the tongue is the body part most sensitive • to touch. • The tongue is connected to the bottom of the mouth • by a thin layer of tissue called the frenulum.

6. What does the Bible say about the tongue? Human speech is a great gift from God. After the flood, God gave the people on the Earth multiple languages. Genesis 11:1-9

7. When it comes to the way we speak, we have a choice. We are responsible for our actions. Speech is an action, and actions have consequences. Proverbs 15: 1,2,4 A gentle answer turns away wrath, but a harsh word stirs up anger. The tongue of the wise commends knowledge, but the mouth of the fool gushes folly. The tongue that brings healing is a tree of life, but a deceitful tongue crushes the spirit.

8. Lesson 10.2 Taste Students will read about the sense of taste and distinguish the difference between sweet, sour, salty, and bitter.

9. Taste Buds The average person has about 10,000 taste buds which are replaced about every 2 weeks. As a person gets older, more of these cells die. Cold foods can make the taste buds less receptive to taste. The four main tastes are: sweet, salty, sour, and bitter.

10. Taste buds send messages to the brain telling you what you are tasting.

11. Lesson 10.3 Nose Students will identify the parts and functions of the nose.

12. God designed the nose to help us breathe, smell, and enhance our sense of taste. The top portion is made of bone while the tip is made of cartilage. Cartilage A strong, flexible material that is found in the body.

13. As air enters the two nostrils that lead to the nasal passage, it moves to the upper part of the throat and eventually to the lungs. The nasal passages have a soft, moist mucus membrane and hairs that trap dust, pollen, and other particles and prevent them from entering the lungs. The nose filters irritants from the air and captures them in the nose hairs and mucus. Sometimes the nose needs to get rid of them right away. How do you think this happens?

14. You sneeze!!!

15. Our noses help protect us from danger and help us understand the world around us. What does the Bible say about the nose and the sense of smell? Exodus 30:22-38

16. Lesson 10.4 Smell Students will read about the sense of smell and use their noses to distinguish various scents.

17. God designed our sense of smell to help us learn about our world. Odor comes from molecules in the air. As we breathe these in through our nose, they move to the nasal cavity. Messages are then sent to the brain telling us what we are smelling.

18. How can your sense of smell protect you?
