this is a science experiment and were trying different ways to stop apples from rotting besides lemon

apply sugar to the cut side of the apple.it stays without becoming brown

Apples, they work better than coffee.

You can show that a tomatoe, orange, or other acidic fruit can be used as a battery.  If you have one of those things that you use to measure ellectricity in a battery, I think you just jab two peices of metal into the fruit and attatch them to the device and it will show electrical current.

5 ways? In 25 years of teaching Biology I have not come across this idea.\nHave a look at the refered site (below) where you may find what you are seeking.

Apples,,,bananas....carrots dipped in peanut butter, cucumbers...light popcorn,,,,peaches, pineapples...hope this helped...

Lemon can not save Apple, Lemon can only Pray for Apple. Jesus Saves!

The apple doesn't fall far from the tree\nhehehehe

Or if you do not have access to a satellite or the UN try these ideas...\n\nFor a middle school project, investigate the best softener to get rid of wrickles.\nFor high school, figure out the best type of light bulb for growing plants indoors.\nFor college, how long you can keep apple juice in a bottle before it goes bad.\n\nGood luck

I've never tried this or heard of it being done, so ask your teacher if it's safe to try this experiment. Take a balloon that has a good long neck on it and force it into the tab opening of an empty aluminum soda can. Then blow the balloon up as hard as you can so that it expands to fill the inside of the can and forces all the air out of the empty can (which really wasn't empty because it had air in it!) Continue to pinch off the neck of the balloon with your fingers so the air won't come out of the balloon. Now fill up a big tall kitchen pot or the sink half way and turn the aluminum soda can upside down completely into the sink or pan of water until the top of the can and pinched off balloon are partially submerged under the water. Now start letting the air out of the balloon gradually and watch the bubbles come to the surface of the water. When all the air is out of the balloon, it still has atmospheric air pressure inside it which keeps the can from being crushed by the atmospheric air pressure of the air in the room above the water level. So try to pull the balloon out of the soda can gradually while making sure to keep the soda can tab and balloon openings under the water level. Results? Does the can get crushed by atmospheric air pressure? Of course, we always have about 14.7 pounds per square inch of atmospheric pressure at sea level. You may have to experiment with different container types that your teacher says are safe to experiment with and one that had the globular shape of a blown up balloon would allow the air to be pushed out fully. You should wear good safety glasses in case any other container (like thin plastic) rather than the aluminum container shatters in the process of imploding.\n \nPS,  Using a wider mouth container, like the aluminum soda can with it's top sawed off, you could pull the balloon out quickly even when it was blown up with air. Don't cut yourself on any sharp metal edges though. The metal or plastic container material can't be too strong and thick because it can't collapse easily then under the force of the atmospheric air pressure.

It's good to discover science, but it's important to know what you're doing because some experiments can be dangerous or even fatal.\n\nSome acids, like vinegar and lemon juice, are safe, but other, stronger acids can cause serious injury.

Try these for bubble gum science experiments:\n\nhttp://www.stevespanglerscience.com/experiment/00000133\nhttp://www.akscience.org/assets/advinstitute/Bubble%20Gum%20Challenge.pdf\nhttp://www.sciencespot.net/Pages/classphys.html#Anchor-49575\n\nIf you are simply looking for information about bubble gum, try the links below.\n\nGood luck and have fun!

Simply there is no money in suggesting apples so their schools wouldn't teach that! :)\n\nGreat tip on the apples by the way!

Experiment w/ what works for you.

the apple would dessicate, or dry out, as the water converted to vapor.  This conversion would be hastened by the low pressure, since the energy of vaporization is proportional to pressure.  So you would get a dried out apple relatively quickly.  But it would not rot because bacteria and fungi cannot survive in a true vacuum.

Do the experiment.  You might learn something.

Aliminum foil and toilet bowl cleaner.  Shake it up and throw it.  We made one once that killed all the grass on a volley ball court, and another one that didn't go off for like 30 minutes, but destroyed the trash can it was in!
