My son loves to push the buttons on the microwave, and set the toaster, but these things should only be done under close adult supervision. Well we probably all have seen this at one time or another. Place a hard boiled egg in a cup of vinegar, and see what happens. After one day, take out the egg, wipe it off with a paper towel and feel the egg. Ask your child questions about what you see and feel.
Carnations Obtain a white carnation.
Fill a clear vase or jar half with water. Color mixing is a good science lesson. Then put the carnation in the water. The child and parent stand at opposite sides of a room. The child wins when they reach you.
