You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)

Based on previous research in similar conditions, it is predicted that the experiment will produce results that support the hypothesis. However, unexpected variables could influence the outcome, so the prediction is not definitive.

a control

To make a balance beam, you will need a long piece of wood or a sturdy beam, padding or foam to cushion the top surface, and a non-slip material to cover the top for traction. Secure the padding and non-slip material to the top of the beam, making sure it is even and secure. Optional additions include attaching legs for stability or painting the beam for decoration.

Experiment can be scientific or psychological. They can use samples and observations to gain insight or mix chemicals together to demonstrate reactions.

A control experiment with respect to that variable. There may be several variables and it may be necessary to leave each one of them out in a different control.

So people can make sure there data is correct on the experiment. For example, if someone did an experiment once and it worked, and then did it 4 more times, and it didn't work, that would be the most accurate answer that it didn't work. If they didn't do it that extra 4 times, they would have thought it worked, when it did not. -Allie(: *Did this question help you? Please, comment if it did*

Get it higher and clear of obdstructions like buildings. Lower the mass of the impeller and increase number of blades, Lower the electrical load until it gets to top speed. Placing impeller in the constriction of a venturi tunnel , like in a jet engine? might be an idea worth trying.

Put a piece of Ivory soap in the microwave for 30 seconds.

An experiment in which only one variable changes is called an "controlled experiment" or "single-variable experiment." In this type of experiment, the researcher manipulates one variable (independent variable) while keeping all other variables constant to determine its effect on the outcome (dependent variable). This approach helps to isolate the impact of that single variable on the results.

-conditions or events that could

affect the dependent variable

(outcome of an experiment) but do

not, because they are held constant

for for both the experimental and

control group.

It is known as the Dependent Variable.

The thing you are experimenting on.

Its velocity would be 635 km/hr, but it wouldn't be anairplane -- it would be a space ship. Well, the only manned spacecraft, that one knows of, will go into low Earth orbit, and to do that one needs to move at 7814 m/s (or 28,130 km per hour). If one wishes to *escape* from the Earth, one needs to be moving a bit faster: about 11,186 m/s (40270 km per hour)!

No, water will not pass through the core of a fiber optic cable. The core is designed to carry light signals for data transmission, and any water infiltration could disrupt the signal transmission process and damage the cable.

the scientific method

Scientific method is a method that people use to solve the problem that related to science. There are some steps like: observe , gather data, do experiment, draw conclusion, and publish or tell to others about your succeed experiment or make a theory.

communicating means sharing your experiment's results with other scientists

Modify the experiment.

The variable that is being tested or changed by the person conducting the experiment is called the independent variable. This variable is manipulated to observe its impact on the dependent variable, which is the outcome being measured in the experiment.

If the tiny wire in a light bulb breaks, the circuit will be interrupted and the light bulb will stop working. The wire, called a filament, is responsible for producing light when electricity passes through it. Without the filament intact, the bulb cannot generate light.
