Does anyone know of an easy, yet interesting, science experiment?

Question

I need a science investigtion experiment . . . Does anyone have any suggestions??

Answer 1

Yes, put a handful of mentos in a bottle of diet coke and watch what happens

Answer 2

Make a cloud in a 2-liter pop bottle (clear bottle works best):
Take a clean empty pop bottle and take the label off so you can easily see inside it. Sprinkle just a little water into it (like one tablespoon max). Add a little smoke - best way to do this is to light an incense stick and put the burning end into the bottle for a few seconds. After you add the smoke, put the cap back on the bottle quickly so the smoke stays in the bottle. Right now you have the ingredients for a cloud in the bottle: water and fine particles (smoke). Squeeze the bottle as hard as you can. The pressure inside the bottle will heat up the air, causing the water to evaporate. When you release pressure, and the temperature cools down inside, the water vapor will condense onto the particles of smoke into the bottle, creating a cloud. It's fun to keep squeezing and unsqueezing and watch your cloud appear and disappear instantly. Relevant science concepts: cloud formation, and adiabatic heating and cooling (how air changes temperature when you change the pressure on it). Have fun!

Answer 3

Here is one for you.

Do a psychological experiment where you ask for help on Yahoo Answer to come up with an interesting science experiment.

The point is that anything you do can be turned into a science experiment. Science experiments are only a different way of looking at things, asking questions about it and being persistent, instead of just taking things as they happen without examining them.

Answer 4

Dip one end of long strip of filter paper into a colored liquid such as ink or food coloring. Watch what happens as the liquid soaks into and moves up the paper. Repeat with different colors or liquids and observe the differences. This process is called paper chromatography. In chemistry labs, filter paper or long tubes of sand are used to separate different materials. In a similar way DNA samples are placed in gel and made to move with an electric current.

For filter paper you can cut up coffee filters. If you can't get those cut up a sturdy paper towel. It works best if the paper doesn't touch anything but the liquid so try hanging the strip over the liquid using clothes pins.

Answer 5

For determining whether or not an electric field is shaped like a magnetic field, try this:
Place copper shavings on;
1) a conductive flat surface ( like a sheet of copper, for example)
2) a semiconductor flat surface (like solar cell material, for example), and
3) a non-conductor (insulator) surface (like a piece of paper, for example)
underneath which two electrical leads/contacts from some source of direct current are positioned so as to alter copper shaving positions in formation of a pattern when current is applied. With conductor and semiconductor flat surfaces, use of a load (a small incandescent lamp or an LED) should probably be located between a lead and its power connection (to a battery, for example, not to exceed about 9 volts, for safety precautions).

Answer 6

boil some water and keep putting sugar in it until the sugar starts to clump up in the bottom and then let it cool. Pour it into a glass. Take a string and tie it around a paper clip and drop the string in the sugar saturated liquid and leave it alone for a few weeks. Sugar crystals will form around the string.

Answer 7

•What consequence does cleansing soap in water have on flowers? Is the end result an identical at very low cleansing soap concentrations in assessment with intense concentrations? •How plenty plant foodstuff is purely too plenty? •Are canines (cats/fish/etc.) colorblind? if so, is the shortcoming of coloration theory compensated by ability of greater advantageous easy/darkish inventive and prescient? •What soils terrific help platforms, which includes homes? •What varieties of words do babies study to communicate first? •Does air temperature impact how long cleansing soap bubbles final? Does relative humidity? •Are goldfish water chemical components rather needed or are they an unneeded fee? •are you able to graft a tomato plant onto a potato plant?

Answer 8

Sprinkle some salt on ice then put a bit of string on the salt and wait a couple seconds and watch the string'll stick. Pretty cheesy. Yay science!

Answer 9

1 thick Coke a Cola bottle or thick glass wine bottle
(more water needed, adjust according because of
dimpled bottom)
1 funnel to fit mouth of bottle
1.5 cup water in coke bottle
3 tbl sp lye mixed into the water in coke bottle

1lg balloon
1 box of aluminum foil first tear off 1 sq foot and tear
into two inch lateral strips and roll up to fit into bottle
Doon't add yet to solution in bottle
1 or 2 twist ties like the ones you get off you bread loaf
wire sandwiched between paper ones
Drop a couple of your aluminum wraps into coke bottle
and put balloon mouth over mouth of coke bottle and
a twist tie around balloon securing to bottle
The reaction of Al an lye will expand and fill up the
balloon with hydrogen, if the balloon doesn't fill
completely pinch off neck of balloon and add more Al
wraps to solution then tie up neck and watch it float
around minus the
bottle

Answer 10

see what type of material a plant grows better in--clay, topsoil, regular old dirt, or sawdust.....alot of variables to measure yet easy to maintain the constants and it pretty much does all the work...you just watch em grow and take notes....
