Elektromagnetic Waves invented by Heinrich Herzt. This episode explains this great invention and the way to the radio.
Sharing the world and all it has to offer with the preschool set can be such a joy! To watch their little eyes explode in wonder can warm anyone's heart. One way that adults can share the awe of our universe with preschoolers is through science projects. Be forewarned! some of these ideas offered can be a bit messy! (That just makes for even more fun, and you know it!)
Topics to cover can be wide and varied. We'll be writing fifty pages of ideas if we were to cover them all! So, we'll hold back a bit and just throw out some of the ideas we have in our conniving little brains and hopefully, we'll inspire some new thoughts that you can carry out. Topics to cover in preschool science could include applied sciences, earth science, physics, and meteorology. Dr. Frankenstein aside, let's begin!
Kids love to play with water. They make it splash, pretend they are deep sea divers or swimming with the mermaids. You can create an ocean for them to observe. When you ta ke a clear plastic two-liter bottle, remove the label and fill it 3/4 full with water. Now... add some blue food coloring and liquid cooking oil, leaving about one inch free at the top of your bottle. The oil and water won't mix, as they are two substances that are physically impossible to mix. Tilting the bottle back and forth will form waves and this will positively amaze the preschoolers.
It's not rocket science! How many times have you heard that? Well, you can create balloon rockets. First, teach the kids a little about the air. Show them how it can exist without us seeing it, that it's invisible but definitely there. Use a balloon as an example by blowing one up. The magic of something you cannot see making something big like a blown up balloon can surprise them in a good way. Now for the rocket (yea!). Take a clear glass and fill it with 1/2 cup of water and 1/2 cup of vinegar will go into a second glass. Add one-teaspoon baking soda to the water and watch w hat happens, which will be nothing but point it out. Now add one-teaspoon baking soda to the vinegar and watch the reaction. These two put together form CO2, although you still cannot see the gas. Put one teaspoon of baking soda into a balloon while pouring one inch of vinegar into a bottle. Place the balloon around the mouth of the bottle, and when ready, allow the baking soda to fall into the vinegar and watch the balloon rise. Now you can let the balloon rip as you loosen it from the bottle. This project also covers Newton's law of opposite and equal reaction.
Slime can be a fun mess for your preschoolers to play with. While teaching the science of chemical reactions, mix equal amounts of white glue and water together. In another bowl, dissolve two tablespoons of Borax. When you add bits of Borax solution to the glue solution while stirring quickly slime will be born!
Maybe you have children that are fascinating by radar. There is a science project you can hav e the children participate in once you have found an uncarpeted room. Have the kids hold hardcover books at chest or stomach level while they face you. Gently toss a ball off the books so it comes back to you. Take notice on the time the ball now takes to return to you. Have the kids back up a couple of feet and do it all again. Repeat these steps as much as you wish and mention distance between one place and another. The bouncing ball represents the radar signals off objects much like a submarine or bat navigates.
Your pantry has things to play with in the name of science. Sprinkle pepper onto a cup of water and show the children how it runs away from your soap-dipped finger. Carbonated soda water and raisins together can show the chain reaction of movement as they bippity-boppity-boo. Form mountains out of Play Doh around baby bottles filled with red food coloring and baking soda. When you add vinegar, you can have your own volcanic eruptions.
When you grab som e lemon juice and write or draw on white paper and paint over the lemon juice images you can create invisible ink drawings.
Celery dipped in water with food coloring will show the plant's veins "grow" magically. Furthermore, you can take some seeds and plant them with the kids so they can form new plant life.
Like we said at the beginning, the list of activities you can do with preschool science is limitless. With a little imagination and creativity mixed well with your pantry goods, amazement and thrills are just around the corner. Sit back, put your thinking caps on and produce the miracles and magic of science!
