Can you tell me some good, easy science experiments for children 5 - 10 yrs. We've done a lot of already!?

Question

I have a sharks tooth - do you think it will dissolve in coke?

Answer 1

The classic egg experiment, you know wrapping it in different materials and then dropping it from x number of feet and seeing if it will break.

Another one, if someone has a tooth they lost handy you can put it in a bit of coca-cola (enough for it to be submerged) and check on it at given time incerements (say, I dunno, every half hour?) until the tooth dissolves (and it will! My mom's a dental assistant, haha), and you can do the same thing with a penny but it will take longer.

Answer 2

I have always liked the experiment, even though initially pretty dull, that shows how weak gravity is. Of the four forces in nature, gravity is the wimp of the lot. Use a magnet to pick up a paper clip. Then watch the magnetic field stretch and propagate as you add paper clips.
Or static electricity is also good like previously mentioned. I always liked picking up pieces of paper with a ballon that has been rubbed on someone's hair.
To show air flow and the forces it exerts, and somewhat demonstrate how a plane flies, take a vacuum and cause it to exhaust air instead of vacuuming it. When you blow air out of a tube or hose, point the tube up, and put a ball in the air flow [like a beach ball, or ping-pong ball i.e. something light and spherical in shape--baseballs don't work very well and kinda hurt your toes when you let go] the ball will bob around in the stream of air. This demonstrates in a way the effects of airflow on an airfoil or wing. The faster moving air on one side causes lower pressure which allows the pressure created by the slower moving air on the other side to lift the wing. Well, when the ball almost falls out of the stream of air, the pressure of the ambient slower moving air exerts more pressure than the fast moving air in the stream and pushes the ball back into the stream. It is easier to do this if the vacuum hose is held very securely and stationary. Usually, the movement in your arm/wrist will mess up the air flow and this will allow the ball to drop.
Take some sort of container, like a soda bottle, and fill it about a quarter of the way with very very hot water. Wait a few seconds and then put the cap on very tightly. As the temperature of the air inside decreases, so will the pressure causing the bottle to shrink and implode a little bit. This can also be done with a metal can and boiling water. Something like a mineral spirits can. It would of course work with a soda can, but I have never figured a way to reseal it.
Enjoy and have fun. For any other ideas, try and find some of the re-broadcasts that are occasionally on TV of the Mr. Wizard series. Physics is fun, just ask Mr Wizard. It may, of course, be easier to find re-runs of Bill Nye the Science Guy, though.

Answer 3

What are you going to do while she will communicate and says, "NO!! i choose that boobie, mommy!" I actual have 3 babies and there is no nutritional earnings of nursing previous 10 months. That purely leaves one earnings...for you. i think of that is gross and sweetness why you will try this while there is no well-being earnings. additionally, you mentioned completely breastfeed. Do you ever choose this toddler to love ingesting nutrition? in spite of babies, the well-being experts propose which you start to introduce toddler nutrition formerly the age of a million. she will choose the aspects of nutrition, and not be taking advantage of the nutrition she gets via you. sturdy Lord...the seen chewing, tasting and swallowing nutrition would be a distant places theory till she is in Kindergarten?! Or do you propose on protecting her with you till she's 12 and beginning kinder then? This sounds extra like a ill obsession than a sturdy theory. sturdy success on looking somebody who has completed this. you be responsive to, some babies do no longer want to nurse and you do no longer constantly get the final be conscious. and a few refuse it after some months. Wow. it incredibly is purely strange.

Answer 4

You can get a paper called litmus from drug stores that change color when dipped in different liquids, this will teach kids if house hold foods and cleaners are acid based or alkaline try lemons and milk tomato's and oranges see the paper change color

Answer 5

get a comb or something that will get enough static. open a water faucet on really low and put the static filled stuff near the low flow of water
