Introduction:Science is fascinating. With a few science experiments using household items, you and your children can observe air pressure, spore growth and properties of light, cooling air and gas bubbles.
The card and glass of water science experiment is more like a magic trick. Pour some water into a small glass and place a card on top of the glass, covering entire opening. Holding the card against the rim of the glass, turn the glass over and observe how the card stays on the glass and the water doesn't pour out.
Why is the sky blue during the day and sunrises and sunsets are red and orange? The sunset in a jar science experiment helps answer this question. Fill a jar with water and then shine a flashlight through the water. It looks white. Now add some milk to the water and stir so the water turns cloudy. Shine the flashlight through the water again. What color is it now? It appears red and orange because the milky water is stopping the other colors from shining through.
Some people conduct mold science experiments in their refrigerators on a regular basis so it might not seem interesting to actually intend to do this. Cut a piece of fruit, vegetable or slice of bread and put it in an open disposable container. Seal it very well with plastic wrap and put it in a warm place. Observe it daily for changes in color, shape and texture. Mold is a fungus and travels through the air as spores that thrive is damp environments. Be sure to throw the experiment away when it's complete and do not perform this experiment if anyone has allergies to mold.
Pour some crushed ice into a plastic water or soda bottle. Screw the lid on tightly and shake the bottle. Set it down and observe any changes. The air inside the bottle is cooling because of the ice so it will start to contract, which will pull in the sides of the plastic bottle.
Pour a jar full of a clear carbonated drink such as 7UP. Add a small handful of raisins and watch what they do. At first they will sink because they're heavier than the drink. Then gas bubbles will attach themselves to the raisins so the raisins rise to the surface where the gas bubbles pop. The raisins then sink again.
Science experiments are fun and can easily be done at home with basic household items.
This is interesting and sounds like great fun to do with the grandkids. I'm afraid I'm about on the level of a kindergartener when it comes to science and will have to do a bit more research to come up with what to tell the grandkids this means in real life, but I'm always looking for ways to have fun with them when they come visit. Educating them (as well as myself in this case!) along with the fun is a real plus! Thanks for the great list of easy science experiments for the kids with household items. High 5!
