Going to the Dentist Expressing Obligation and Necessity 9:30am - 9:45am Ice Breaker What was the best thing that happened this last week? What was the worst thing that happened this last week? Every six months, I visit my dentist for a regular dental check-up. At the dentist's office, a dental hygienist will bring me into one of their private patient rooms and x-ray my teeth and gums to detect any problems inside my teeth. Then, the dentist reviews the x-rays and checks my teeth to see if I have any dental problems like cavities. If she sees any cavities, she will clean and fill them. Of course, she first will give me a shot so I don't feel any pain. After that, the dental hygienist will clean my teeth by removing any plaque buildup on my teeth. Plaque contains bacteria that can damage your teeth. The hygienist will also polish and floss my teeth at the end. I will also have the dentist whiten my teeth this time using a special procedure in her office. My dental insurance covers part of the cost of the dental cleaning and teeth fillings, but it doesn't cover non-essential procedures like tooth whitening. 9:45am - 10:00am Vocabulary and Conversation Directions: Explain and give examples of any new vocabulary.

There were also other boats with them. 37 A very strong wind came up on the lake. The waves came over the sides and into the boat so that it was already full of water. 38 Jesus was at the back of the boat, sleeping with his head on a cushion. His followers woke him and said, "Teacher, don't you care that we are drowning!" 39 Jesus stood up and commanded the wind and said to the waves, "Quiet! Be still!" Then the wind stopped, and it became completely calm. The Word You May Not know: followers = followers of Jesus who believe His teaching; drown = to die under water; command = to tell someone to do something; completely calm = fully quiet Questions from Mark 4:35-41 1. Did the experienced fishermen handle the storm well? 2. What would you do if you were one of the disciples in the boat? 3. What do you do when you face an unexpected life storm (illness, relationship, financial challenge, job loss)? 4. Do you think such a powerful Jesus can help in your unexpected life storm? 5. Jesus followers woke him and said, "Teacher, don't you care that we are drowning?" The disciples seemed to think Jesus didn t care. Do you think Jesus cares about your storms? What would you say to him if you needed his help? 4
6. Have you ever experienced any life storms? What are they? (Ex., difficult relationships, health, financial challenge, death of someone you love, and etc. ) How did you overcome the life storm? If you are in the middle of a storm right now, ask your teacher to pray for you! 7. Quiet! Be still If Jesus said this word to your life today, what would it mean to you?
