I. GETTING READY FOR BED. 1. At what hour do you go to bed? When do you get up? How many hours' sleep does this give you? Is this enough? Why do you need so much sleep? 2. As you undress, what do you do with the clothes you take off? Why should you air your clothes every night? How can you take an air bath? Is this as good as a wash? 3. How do you care for your hair at night? 4. Do you ever go to bed without brushing your teeth? If you do, what happens all night long to the food scraps that were left around and between your teeth? As these scraps decay, what harm do they do? What makes a tooth ache? 5. Draw a little picture of your own teeth as you see them in a looking-glass. Are there any spaces that you can see where food might lodge and stay? How can you keep your teeth quite free from scraps of food? 6. Why are teeth necessary? How must they grow to make good cutting tools? If they are not straight or sound, what can you do about it? 7. Why ought children's first teeth to be thoroughly brushed every day? II. THE LAND OF NOD. 1. When you are ready for bed, how do you fix your windows? Why is it even more necessary to have the air blowing through the room at night than in the daytime? 2. How else is your body being purified at night? Does your body do any work while you are sleeping? What work? 3. What kind of sleep should you have if you are perfectly well?
