which food molds fastest

The Variables That do not change in the experiment

Independent variable and dependent variable

It is possible to use control group in a sentence as long as it does make sense.

maybee

Tin, lead or copper

Intel education in science

what may happen if remove the lid of petri plate containing nutrient agar and place the lid on benchtop

yes many people have done a permanent marker science fair project its really easy and fast i bet im going to do it based on it for a science fair project.

Any age. Easy and fun

Objects that do not have a power source, will eventually take up the same temperature of the room. Measuring the room temperature, gives you a baseline energy level, so that energy levels of other objects can be monitored

mini wind turbine, non neutonion fluids, circutry

it mean the result of your whole project like a short summary

Dependent upon the variables, you need to take into consideration factors that can affect the outcome of the result; what will make the result vary in any way.

If this, for example, entails the variable to be kept constant time, you will monitor the time and repeat it throughout the experiment.

This is my understanding of constant variables; hope this helped.

at the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.

It is called a control group.

Salt water is not considered pure water because it contains dissolved salts and minerals. It is classified as a mixture, where the salt is the solute and the water is the solvent. In comparison, pure water contains only water molecules with no additional substances dissolved in it.

The sugar is needed as food for the yeast. The yeast gives off carbon dioxide as it digests the sugar. The carbon dioxide could be used to inflate the balloon. Without the sugar, the yeast remains dormant and does not give off carbon dioxide.

All you need is a black sharpie marker, an eye dropper, some water, a coffee filter and eyes. Take the sharpie marker and draw a dot about the size of a dime on the coffee filter. Next take the eye dropper and fill it with water. Then drop one drop of water in the center of the dot and you will be amazed on what colors make up black!

Thanks for letting me help you!

i dont kno i am tryin to ask yall people:o

Henry Cavendish was an important figure in the fields of chemistry and physics. He is best known for his discovery of hydrogen and for accurately measuring the density of Earth, which helped determine the mass of the planet. Cavendish also made significant contributions to the study of electrical conductivity and heat.

A hypothesis is a tentative theory which is unverified, but if true could explain selected facts or observations. A hypothesis expresses an opinion which isn't necessarily based on provable evidence.

A theory is a little more solid than a hypothesis, so a hypothesis when tested and proved to have some basis might become a theory.

A theory might also refer to a belief with little or no fact behind it at all: he has a theory that the month in which people are born affects their personalities.

Most of the plastic have materials that help in prevention of evaporation it act as a shield so that water does not gets fade away. That why plastics are being used as a prevention methods for storing food articles & save them spoiling.
