You will need English muffins, Pizza sauce, Shredded cheese, Olives, Mushrooms, Pepperoni, ground beef.
Have children put together their own pizza. Then divide the pizzas into two groups. Cook half in the oven on 350 degrees for about 5 minutes. Cook the other half in the microwave; you can cook about for a minute and a half. Talk about how people used to only have ovens, which take much longer to cook in then microwaves do. Ask them how they think we will cook our food in the future? Will it cook faster than the microwave?
