In this PPT you will find a list of different foods that will help you fall asleep. Each slide contains the type of food, a picture of the food and a brief explanation why that food makes it easier for us to fall asleep. It's great for an interactive discussion class. Students learn about the health benefits of different types of foods, get an opportunity to give advice to others and discuss their advice with the class. I've been teaching a class about food for more than two years and used this PPT a couple of times. The students always found it interesting. It gives you an opportunity to teach the students something new in their target language as well as using the newly acquired language. I suggest keeping the class loose and fun with a warm up about sleeping habits and what the students do when they can't sleep, followed by a discussion on what you should or shouldn't do to help you sleep. Then introduce the foods on the PPT (you might have to explain some of the more advanced words in simple terms or look those words up in a dictionary) and go through them one by one, giving the students the opportunity to take notes. After you showed the students all the different types of foods, close the PPT and ask the students how many different foods they remember, then ask them to work in groups to come up with a plan on how to incorporate those foods into our diet.
