Science Experiments

Yes, sugar is soluable in alcohol. I am assuming you mean drinking alcohol although it is soluable in all organic alcohols. The hyrdoxy (-OH) groups on both the sugar and the alcohol allow for hydrogen bonding, making sugar very soluable in alcohol. Hydrogen bonds are also the reason sugar is so soluable in water.

A catchy Title would be "HOT OR NOT."

If you place an iron pyrite cube in Mercury it will produce about a millivolt of current in water. More in salt water or vinegar or free radicals. This is a completely unexplored way to generate free electricity. It is not due to galvanization since the cube is the dependent aspect. Take the cube out and the amperage disappears (slowly but surely over time). This indicates both a capacitance and current generating characteristic that is unique to the interaction of the cube and mercury and the water provides the connective volt potential (although a different medium would yield better results.

Temperature, pressure, and common ion effect

During anaerobic respiration, cells produce energy without the presence of oxygen. The process begins with glycolysis, where glucose is broken down into pyruvate. In the absence of oxygen, pyruvate is converted into either lactic acid in animals or alcohol and carbon dioxide in yeast and some bacteria, generating a small amount of ATP.

Those in a control group would not know they are in the control group, and they would not receive whatever manipulation that is being tested. If it is a drug being tested, those in the control group would receive a placebo (typically sugar pills or saline injections). If it is a behavior being tested such as exercise, the control group would either do a behavior like reading that has nothing to do with the experiment, or they would just mentally visualize that they are doing what is being tested (such as pretending to exercise). Now, if visualizing is the experiment, then maybe there should be two control groups, one that actually does what is being visualized, and one that does a more sedentary activity that has nothing to do with the experiment.

Charts and graphs are used to organize and present data from an experiment in a visual format. They produce a visual representation of the data that can be quicker and easier for a reader to interpret. Graphs may also help to indicate patterns and trends or point out other properties of a set of data. They often help to make better sense of a table full of numbers.

coloring doesnt matter. an ice is an ice cube. now, if that coloring is due to chemicals mixed into the water, then there'll be a difference in how fast it'll melt, but otherwise, they will melt at the same time.

In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.

If in your experiment, whole wheat bread has molded faster than other breads, you should look at the ingredients used to make the bread and the processing conditions where the bread was produced. The wheat bread could have been exposed to more mold to begin with or the other breads may have used mold inhibitors.

it is called pure science.

In split-brain experiments, where the corpus callosum is severed, individuals may exhibit disconnected behavior between the two hemispheres. This can lead to peculiar responses when information is presented separately to each side of the brain. For example, a split-brain patient may be able to verbally report information presented to the right hemisphere but not the left, as language centers are generally in the left hemisphere.

organic chemistry- the study of carbon and its compounds

inorganic chemistry-the study of all the properties and characteristics of other elements.

analytical chemistry-the analysis and identification of substance

physical chemistry-the study of laws and principles govering physical and chemical changes

biochemistry-the study of materials found in living organism

This delightfully simple experiment may be used to estimate the percentage of oxygen in the air. Assumption is that all the Oxygen is consumed.

Mount candle on a small watchglass floating on water, light the candle, and place an inverted beaker over the whole to create a water seal.

Measure the rise of the water inside the beaker.

The increase in surface area of reactants increases the contact between reacting molecules, atoms or ions so the rate of reaction becomes increased.

There are several uses for a staining jar. In microscopy, it is used for staining tissues and cells for slides. After being stained with dyes or stains, the specimens can also be placed in the jar to look for certain aspects.

The slight dip in a graduated cylinder is called a meniscus.

Scientists do experiments to see what is going to happen. First, they make a hypothesis or guess about what they think will happen. Then, they do an experiment to see if their guess is right or wrong.

The diaphragm goes down, pulling air into the lungs. Your ribs expand, helping your lungs to expand also.

ummm you can predict which ball goes further whether the ball if it is wet or not.
also if it will go further under higher pressure or lower pressure. hope I helped
