Place each egg by the sticky note of the glass it was in. Rinse them in cool water and pat them dry with the towel. After 12 hours, remove the eggs from the glasses of soda one at a time.Leave the eggs in the glasses for 12 hours. Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2.Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1.Squeeze a big dollop - about one tablespoon - of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes. Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes.Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2.This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do. These are mostly designed for preschoolers through elementary schoolers, but if you have a younger one, you can check out these 1-year-old learning activities, toddler learning activities and preschool/kindergarten learning activities, some of which also cover STEM subjects. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. These kid-friendly experiments cover magnetism, surface tension, astronomy, chemistry, magnetism - you name it - and in ways that lets kids really see how the forces around us work. So, next time you need a bordeom-busting indoor activity on a rainy day or a DIY project to keep them busy, pull out one of these ideas and get them to start making hypotheses. You probably have most of the materials you need to do these science experiments for kids sitting around in cupboards and drawers. So while a kid who is interested in the subject might have fun with STEM toys and science kits, you don't actually need to go out and buy something special to keep the STEM learning going at home. Science, and the scientific method, are just ways of describing what is happening in the world around us.
