Given a line L and a point P. Reflection P' of P in L is the point such that PP' is perpendicular to L, and PM=MP', where M is the point of intersection of PP' and L. In other words, P' is located on the other side of L, but at the same distance from L as P. P' is said to be a mirror or...
Coca Cola dissolve the calcium on the chicken bone.
This is totally unanswerable. The temperature of the water depends on its total environment. Whilst the sun is a source of energy, it may be shining on the outside of the dark room and heating it up. There may be other heat sources keeping the room warm. There may be a wind blowing outside,...
Yes, but remember: it's okay to be wrong!
What is the part of an experiment that is treated just like the experimental group except for the one factor being tested?
Im in 7th grade and i learned it like 3 years ago. its the variable.
What are controlled and uncontrolled variables in an mold experiment using milk bread bananas and cheese?
Controlled -time, temperature, location, age at start.
That depends, what are you doing with the dry ice? If you are testing how it would melt, the title could be "Dry ice in melting stage" or :How does dry ice melt?".
Scientific method is described as a scientific approach to a problem. To solve a problem you must first find the problem, access it, hypothesize a solution, illustrate your solution, try the solution, and then finally try it. If this does not work start over.
The conduct of electricity
Yes! Not many people know this, but it actually can. I had tons of fruits + a potato in my science project, which was to see what would produce the most electricity. My hypothesis, was of course, a lemon, but I came to see that somehow, the pear was higher than everything else, even the potato! With...
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change...
Pinwhel connected to a coil of wire that rotates within the magnetic field of a (or 2) permanent magnets.
What are the benefits and constraints of using the scientific method to analyze environmental decisions?
1. generates/gives new information about an event or phenomena. 2. produces new material3. solves an existing community problems.
Amino acids are organic molecules which proteins are build from. There are twenty. However there is two amino acids which are acidic: Aspartic acid and glutamic acid.
The two factors influence one another since air is the key relationship between them: the rate of motion of air and the degree of hotness or coldness of a substance.
The use is telling how hot or cold the room is
areas of rising air and low pressure. When air rises it cools, and the moisture it contains condenses out as clouds, which eventually produce precipitation.
Igneous rock is formed when magma cools and solidifies Magma can be forced into rocks, blown out in volcanic explosions

The solvent, usually water, is boiled off by the addition of heat energy, often under reduced pressure Condensation is the opposite of evaporation and has the same temperature as the BP of the liquid. When heat energy is removed from a gas or vapour, it begins to condense
If you are not doing an experiment, there is no variable.
It is not possible to draw a structural formula in the Answers text editor.
The genetic experiments Mendel did with pea plants took him eight years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type.
It is difficult to determine the absolute age of a sedimentary rock because sedimentary rocks are made up of diverse particles that are all different ages. As a result radioactive dating can only determine the age of the particles, not the whole rock.
Two, the dependant and independent variable. The independent variable is what you are changing in each test and the dependant variable is what factor is being changed in it. There is also the baseline data which you are comparing everything to. For example if you are doing an experiment of whether...
Electricity is "created" when certain chemicals react together. We use chemically- made electricity to power many machines from flashlights to a watch or sometimes a car. Yes, there are cars that run on electricity! The devices that store electricity are called batteries....
This is a fairly easy experiment to set up, provided you can get round the fact that people can be put off if food doesn't look the way they expect. You would need to use something like a pate or custard type pudding. You can colour these without changing the taste, then ask people to rate...

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...

The chemistry behind even the most simplistic of experiments can baffle most, such as the bubbling as a result of salt being added to soda. Soda itself is already "bubbly" due to its carbonation, but add a dash of salt and it bubbles even more violently than on its own. This bubbling effect...

it helps in bringing to a conclucion whether we are right or wrong
genus, then species (homo=the genus, sapiens=the species)
It is called a control group.
Well, what i do is make fake data and if you need pictures of the experiment get them off the computer and call it your pictures. If you for whatever reason cannot get your project done on the last night you can go to freesciencefairproject.com and it will show you answers to your project ;)
Usually fluids get denser when the temperature drops. They get denser and denser until they turn solid. The same thing happens to water except that water is the densest when it is around 4°C. When the temperature drops towards 0°C it's density lowers. And also the liquid form is denser...
an explanation of an observation
This is a non starter because horoscopes may be fun but they are not science. Even if you set out to find out if there are correlations between star signs and anything else, you are not going to get a large enough sample size to be meaningful. Why not do something astronomical instead,...
The results of an experiment are called your data.

There isn't really a "purpose" for harmful bacteria, or anything else, in the scientific sense (perhaps what you really meant to ask was "Why did God/the gods create harmful bacteria?" but then you should have put it in the Religion category). Some bacteria are "harmful" because that...
something that a person thinks that is true that other people question
An idea like that is in a scenario when research on the idea can prove it right or wrong.
it mean the result of your whole project like a short summary
Because every good scientist should have good habits.
All single celled organisms are placed under Kingdom Protista. This kingdom forms a link between other kingdoms of plants, animals and fungi. Members of Protista are primarily aquatic in nature.
How much sugar, how much water, how warm is "warm", are you stirring it or not, is the sugar powdered, in the form of small crystals, in the form of rock candy ... there are so many variables that it is impossible to give an answer to a question this vague. However, even if you had...
The melting point is the temperature at the solid and liquid states of the material are in equilibrium; if the temperature is even very slightly above the melting point, the material will melt, and if it's even very slightly below, the material will freeze. Technically the melting...
1. Purposing-students decide what particular learning task to accomplish with the teacher allowing them to decide on thier own. 2. Planning- 3. Demonstration Proper 4. Executing 5. Evaluating
The outcomes must be repeatable because if the outcome keeps changing, then something must have changed during one of the experiments, giving you the different outcome.

How did the scientific method differ from the way in which the ancient Greeks tried to understand nature?
I have an ongoing issue with my bladder or uninary track. The bestway to describe it at first was that I was getting performanceanxiety while having to urinate in a public restroom or leaving aurine sample while being filmed at my methadone clinic twice aweek. I had no problem doing this for a long...

Buttrflys can only live for 2 days or until their wings touch ahuman or animals skin/fur.
You may need to be a bit more specific. Lead is commonly used for X-ray shielding ... for example, if you have your teeth X-rayed at the dentist, they'll put a sort of lead apron over you to protect the rest of your body (I must confess that it's not terribly reassuring that the barrel...
It is important because those are the things that help you manipulate the manipulated variable
You want to see if mold grows faster on bread in the shade than on bread in the sun What if your experimental variable is?
The experimental variable is the light condition of the growing mold.
the balloon would float because the helium inside the balloon would pull it up, but if you had a weight or hand on the bottom, the weight or hand would keep the balloon from rising away. ***** Also, helium is lighter and less dense than air and will float upwards.
BC Hydro's (In Canada) various facilities generate between 43,000 and 54,000 gigawatt hours of electricity annually, depending on prevailing water levels. BC Hydro's capacity is about 11,000 megawatts.
lets say the gas is evaporated water it must get really cold to turn into a solid when that processes happens the molecules slow down a lot to make a solid and do the opposite and heat it up to turn it into a liquid.
No. Chemicals should be disposed of in a safe manner. Usually directions for disposal can be found on the box/tube/packet that the chemical came in. If none can be found, ask a professional (teacher, lab assistant, poison control expert) what is the proper disposal for a certain chemical. Excess...
An experiment gives us proof that we are right.
It can really be either or, a mixture because it includes many products and a solution because two parts (dressing) and (veggies) have been mixed to form a solution.
Depends on what type of seed you're talking about. Most seedssimply need the right temperature and the right amount of humidity.An easy way is to put a wet paper towel in a bag, put the seed inthe paper towl, and put it in a warm place in the house.

In Rutherfords gold-foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positvley charged center because?
When the beam of electrons passed through the gold foil, some were deflected at odd angles. This indicated the presence of a more massive portion of the atom that could be explained by the raisin pudding model.
It is possible to use control group in a sentence as long as it does make sense.
Principle of Working:A Moving Coil Galvanometer works on the Electromagnetic effect of current carrying coil (free to move) being placed in an air-gap between the soft iron core and the strong pole pieces of the magnet. The current following in the moving coil which is the specimen to be sensed or...

You don't need to prove much - just look at the definition of a vector. A vector includes a magnitude (in this case the force), and a direction. Since weight (or "the force of gravity") is directed to a certain direction, namely downward, you can consider it a vector.\n You don't need to prove much...
sampling theorem is used to know about sample signal.
No; all around us, all the Universe is matter in different known or still unknown state.
First, the science behind a hard-boiled egg: Egg whites are made of water and proteins. Proteins are made of long chains of amino acids, but in an egg the chains are clumped tightly together in individual spheres. (These are called "globular proteins.") When the egg is heated, the proteins and water...
Its a general verdict that girls are better at guessing. But that's not true. Every human is different and guess work is pure luck. Yes, mental abilities of a person can come handy.
