Have your children take a piece of bread and wipe their hands on it. You can additionally take it into places that germs hide (bathrooms, sinks, diaper changing stations, etc) and rub it on it. Then put the bread in a baggie and put it in an area where the kids can watch the germs grow on the bread. This will be a great thing to help get your children to wash their hands Obtain x-rays and let your children discover the human body through them. After explaining to your children what germs are, tell them that you are going to pretend that glitter is germs. Put glitter on your hand and shake a child's hand. Show the children how that child now has your germs. Let that child shake another child's hand. Continue until all children have glitter on their hands. Then one at a time have your children wash their hands and show them how the germs (glitter) have disappeared Obtain cheap stethoscopes or make your own (tissue rolls). Let your children listen to each other heartbeats. Then have them exercise for a few minutes and listen to each other heartbeats again. See if they can tell a difference. Talk to your children about why we sleep and how it makes them be able to play longer and have more fun Make two faces one happy and one sad on the bottom of a paper sack. Cut the mouth of the face out. Bring several cut outs of different kinds of food. Have the children sort, which ones are healthy (happy face) and which ones are bad for you (sad face)
Get a few common snacks (carrots) and their baby food equivalents. Let the kids try them and compare their texture and taste.
Have the children make a pyramid shape from construction paper using brown for the base (breads, pasta, rice) Green for the next level (fruits and vegetables) Red for the next level (meat, eggs, fish) and purple for the top(fats, candy, etc). Then they can cut pictures from magazines and collage them onto the proper food group. You can talk about how more pictures fit on the bottom levels because they are healthier and how only a little bit of treat pictures fit on top because you shouldn't eat too much of it.
