Yes. Get some help from a favorite science teacher. Have some interesting ideas to explore and start! Also you find information in the library or the internet about science fairs and ideas.

Controlled or the Independent.

Radio controlled refers to something that is controlled by remote means via radio frequency, such as radio controlled cars or planes. It is slightly different than remote controlled items which usually have a wire connection.

To make sure what you publish is correctly, and to provide crosscheck of your methods and results.

Answer it for me.

That all matters are made up of atoms

It depends on the type and size. A 16 oz bottle of Apple Cider Vinegar costs about $2, the same size bottle of Balsamic Vinegar costs about $11. The costs also vary for White Vinegar, Red Wine Vinegar, and so on.

Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.

These are the most simple pipettes, used to extract and deliver pharmaceutical products.

A physical change is when the same compound/chemical just changes form, for example, water experiences physical changes when it goes from ice to a liquid to water vapor (a gas or steam). A chemical change is one where bonds have changed, therefore the molecule that started the change, is now a completely different molecule. For example, burning glucose in oxygen gives you carbon dioxide and water. Notice the glucose has combined with the oxygen to form completely new chemicals, i.e. CO2 and H2O. (It is worth remembering that burning is a chemical reaction with oxygen.)

Pls Vote if you agree with it :))))))thx

The mold is there because it has a role in which must be played in Nature-to break down organisms. It will take over the orange so it will be overcome by it. In a way it is a form of parasitism. I'm not sure if I would call it parasitism. A parasite usually affects a living organism, if the mold was growing off of a living orange tree then it would be a parasite, but as for an orange? I would consider it more of a decomposer then.

Torricelli's experiment: Spring 1644, Florence (Italy): Venue of a famous experiment: Torricelli did his experiment with quicksilver or mercury. He proved two things with this experiment: 1, Nature doesn't abhor the void (nature doesn't fear vacuum) 2, and that the air has weight: He used a glass barometric tube of about 1 m in length which was open at one end and closed at the other end. He also used a glass funnel, which was used to pour in mercury. He put the glass funnel inside the one end open glass barometric tube of 1m and poured mercury into it. He used this method to avoid the formation of any air bubbles inside or in other words, it was not to create any void inside the tube. He removed the glass funnel after pouring the mercury, and then closed one end of the barometric tube with his finger, inverted it to make the open end at the bottom and the tube was inserted into a vessel containing mercury carefully without forming any air bubbles. He found that the mercury in the 100cm tube dropped to 76cm. He did the same experiment with water. But that required a long tube. Water has a density 136 times less than that of mercury, and this experiment returned the water column at a height of 103m. This means that the height of the water column = the height of the mercury column (76cm) X relative density of water with respect to mercury (136).

yes it would be in that category, also you should think about what enineering would be involved! great idea though:) How are you planning on preserving water with a shower head that expells water?

compress it nearly impossiable to COMPRESS solids and liquids

Friction, when moving sideways.

Upthrust when you are trying to go down.

gravity when you are trying to go up

Contrary to popular expectation, rubber is not really elastic, atleast not the way scientists define elasticity. Rubber is actually much less elastic than steel. Thus for best results we use steel or similar materials, say brass, in this experiment.

let her get card board and makes and glue and make a penguin on ice

There are a number of challenges that are faced during field work. Not knowing the environment for example can be a huge challenge.

Many types of signal exists.
