![]() 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. When you tilt the dish, the fish moves around on the water’s surface.įrom Good Housekeeping Amazing Science: 83 Hands-on S.T.E.A.M Experiments for Curious Kids! See more in the book » Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. The easy-release ink lets go from a surface, but why does it float? There are two reasons. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!) It’s made with a chemical that causes it to easily release from surfaces. The ink in dry erase markers is engineered to be slippery. Tilt the dish slightly from side to side.If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again. The water will move toward your drawing, eventually surrounding it. Be careful not to pour water directly onto your drawing or make splashes near it. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Fill the measuring cup with tap water.Retrace your drawing to make sure all the lines are connected. ![]() ![]() Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker.Here's another one that deals with solubility and density. These experiments are mostly designed for preschoolers through elementary schoolers - with a couple that are either demonstrations or better for older kids - 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. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. So, next time you need a boredom-busting indoor activity on a rainy day or a DIY project to get their minds humming, try one of these best at-home science experiments for kids, which cover topics like cover magnetism, surface tension, astronomy, chemistry, physics and more.įirst off, it's good to start them off with the scientific method. It's all science that you can do at home, most likely with ingredients you already have in your house. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures. Or sending vessels - rockets, tea bags, airplanes - soaring through the sky for impossible distances. Imagine blowing the biggest bubbles imaginable - or even making bubbles within bubbles.
