Yes it travels up the small strings which when it is a plant transports water and mineral to the cellery's cells. Put it tail up in a glass of colouring and it will change. Can take a few hours.

you can tell because it is a wedge i think but i need this answer or im going to kill my self and i will fail science. so please give me money so i can run away and buy myself food and a gun and a box of bullets and i will take care of the rest with one by one in my fliping head..... Thanks :)

You could always use a light or clear jello for the cytoplasm, and use things around the house for the various insides, such as: Cereal, dryed beans, ribbon, hard candies and more. Hope this helps.

You could research and create a project on why it dissolves so fast in your mouth or how hot air can cause sugar to melt!

what do i need to make the parthenon

Background information is the information that you already know about the subject. It may also include why you chose that particular project.

To make a working model on energy resource and conservation there are several steps. The first step is to make a propane wheel. The second step in this model would be to attach piping to six containers and create a circle with these containers. The bottom of all six containers should be submersed in water. Lastly, fill all of the containers with propane

Charcoal shoe polish can be made an home easily. Major ingredients include a hard type of charcoal, 5-6 drops of kerosene, water, a sachet of citric acid, a piece of hard bar soap, and one cap of liquid paraffin or glycerine.

you do research than you build it.

if in grades, say 6th to 10th grade. a simple , but perfect experiment is the (what i call it ), is the open flash light experiment. on a small piece of wood , put two D size batteries together positive to negative, and positive to negative. they are in series's, meaning 1.5v + 1.5v =3v flashlight. on the negative end (flat end) connect a wire to it and let it go to a knife switch. from the other end of knife switch, connect a wire to the side of a flashlight bulb. you can glue or tape to it as long as it makes contact. from the positive side of the two batteries (raised end) connect a wire to the pointed bottom end of the bulb. you can call it Open View Of how a flashlight works. close knife switch, current flow through bulb and it lights, (closed loop). Open Switch, no current flows. bulb does not light(open loop). a very simple series circuit, but very effective in showing how electricity works.

Due to power consumption on the Game Boy Advance on most AA batteries you will receive around 15 hours of game play.

you might want to try this website out it really helped me, and its really good: http://www.thinkythings.org/carafe/build.html Hey,To Make a thermos is infact quite really easy. I had to make one to, to hold an icecube from melting. First find a container but make sure it is not a conducter of heat like metal. So Something like plastic would be fine. Then wrap the whole contanier with aluminum foil.Around that cover it with duct tape.Inside put about 4 peices of fibre glass found usully at homehardware. Also add ice packs and open them and use the materials inside. Put the lid on top and voila IM FOR SURE it will work. Good Luck:)

yes.we can feel

Who invented the potato battery? Alessandro Volta.lol maybe that's why it's maybe called volts

Measurement information that is used to describe something is called data.

The standard for comparison in an experiment?

da that's what they asked don't have to repet the question

A variable test?

Terrestrial microwave technologies share with satellite microwave technologies many of the scientific and technical improvements used to accomplish microwave transmissions. They are different in that satellite microwave technolgies seek to neutralize the effects of the atmosphere in the microwave transmissions. On the other hand, terrestrial micowave technologies seek the aid of atmospheric effects on microwaves to extend the range limitations imposed by the Earth's curvature. Examples of these terrestrial technologies include those used to exploit troposcattering and meteor-burst in microwave communications--not used at all in satellites. Professor Martinez

Well, I believe the control group acts as a standard for comparison in an experiment because it does not change, so it can be compared to the variables that do change.

You would use division or multiplication depending on which way you were converting liters and milliliters. To convert liters to milliliters, you would multiply by 1,000; to convert milliliters to liters, you would divide.

The 'Variable' is the difference in the experiment that acts as the unknown factor.

Results are drawn based on what the Variable does.

A battery is a storage tank for electrons. The battery runs things from stored power created elsewhere. Think of it like the hot water heater, you want a longer shower, get a bigger tank. But if the water is shut off, the shower is a moot point.

A solar panel makes power from sunlight. The solar panel is most like a generator, but a generator makes power from gasoline.

Electricity moves at the speed of light, so if you don't have a battery to catch the power made by your generator or solar panel, the generator or solar panel must be on to run the appliances. A battery allows you to catch small amounts of power all day, and then turn on the microwave when you need it.
