Use an incubator to hatch a baby chick. You can order an egg from several Internet sites or ask a local hatchery (most will be happy to help out a school) Put a hardboiled egg in water. The egg will sink. Tell your children that you are going to add salt to the water and ask them what they think will happen. Once you stir in enough salt the egg will actually float. If you live somewhere that gets particularly hot. Take an egg outside and show your children how that you can fry an egg on asphalt. My children were amazed at this. Put several eggs into different liquids (cola, milk, orange juice, etc). Discuss with your children what they think will happen to the eggs in the different liquids. Leave the eggs in the liquids for a couple of days. When you take it out the kids can see what the liquids would do to their teeth. Put several different colored Easter eggs in a egg carton. Show your children the eggs and then shut the carton. Ask them to remember what colors were in what location Put a boiled egg into vinegar for several weeks. The egg will become soft and leathery like a real dinosaur egg might have felt. You can carefully take it out and let your children feel a "real" dinosaur egg. Talk to your children about all the animals that come from eggs (birds, snakes, turtles, fish, lizards, etc) They will be amazed at all of the animals that come from eggs. This goes great with the book: 'Chickens Aren't the Only Ones' Boil an egg in water with a tea bag. The tea bag will stain the egg brown. You can then give your children a toothbrush and let them brush the egg. The stains will disappear as you brush. Explain to them that this is what brushing your teeth does
