It seems like there may be a typo in your question. If you meant "results," then it typically refers to the outcomes or findings obtained from a process, experiment, test, or investigation. Results can provide valuable information and insights to help guide decisions or actions.
How do you keep chicken bones from turning black?
I understand that due to the rapid weight gain of chickens because of the growth hormones used they are slaughtered younger, but with good weight. Because they are young the bones are not yet densely calcified. As the chicken ages the bones become more dense and seal porosity. In years gone by they aged longer before slaughter and had adequate bone density to seal in the marrow in the bones, now they are not old enough to have the bone density to seal marrow. Through the cooking the marrow leaches out into the meat and causes the dark color.
How do you figure out the variables in a science project?
The variable that you change is the independent variable(which you change). This could be the amount of light, fertilizer or salt that you give to a plant to observe how it affects its growth. What you measure is the dependent variable(the variables that change due to the change in independent variable) eg mass of the plant each day or week, number of leaves or height. All other variables are called the control variables(variables that are constant throughout the experiment). These make the experiment a "fair test". In the above experiment if you were to vary the amount of salt in the soil then each plant must be given the same amount of light, fertilizer, water etc.
I need an abstract for which toothpaste whitener works the best science project?
This science project aims to determine which toothpaste whitener is most effective. The study will evaluate popular toothpaste brands known for their whitening properties on stained tooth samples to measure their whitening effectiveness. Results will provide insight into the most effective toothpaste whitener for consumers seeking whiter teeth.
What projects are there with Acids and bases?
Some projects that are related with Acids and Bases are those that deal with either finding the pH value of a solution or liquid, or when you use the pH value to find whether a liquid is an acid or base. A project I did involved using a liquid that was exactly neutral and a color code (which you can find anywhere online) to see whether or not a household liquid such as lemonade or bleach was an acid or base
What are Fahrenheit and Celsius examples of?
Both Fahrenheit and Celsius are ways of measuring temperature. Both are measured in degrees. Water freezes at thirty-two (32) degrees Fahrenheit and zero (0) degrees Celsius.
What describes a reason for making a prediction when doing a controlled experiment?
To anticipate the observations or measurements that will be made is known as an HYPOTHESIS.
How long does it take algae to grow in regular water?
Ordinary ground water? A few days can see the algae form.
What is the objective for a homemade lava lamp?
The objective of a homemade lava lamp is to create a fun and visually appealing decorative item that mimics the mesmerizing movement of lava inside a lamp. It is a simple and entertaining DIY project that can be enjoyed as a science experiment or as a unique decor piece.
What are some fast growing house plants for a science fair project?
Lettece grows in about 3 weeks, also beans grow pretty fast. but if your project is due in less then 2 weeks your out of luck.
What are constant variables and y r they important in an experiment?
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
What are the predators for a cat?
Cats predators would include dogs and the wild Canines (wolves, coyotes, foxes).
Birds of prey would also be predators (hawks, eagles, etc).
And, of course, typical diseases (bacteria, viruses, etc). Cats are also susceptible to food borne toxins for example rat poison from hunting poisoned animals.
What is a great science fair idea for an experiament?
Question: Does microwaved water affect the growth of plants?
Hypothesis: The experimenter thinks that the hotter the water is the worse it will be for the plants.
Materials:
1.) Distilled water 4.) Same soil
2.) Same plant 5.) Same pot
3.) Microwave 6.) Measuring cup
Procedure:
1.) The first day the experimenter starts the project, plant the same plants into the soil and the same pot.
2.) When the experimenter first plants them, he has to microwave about 2/3 cup of water for one minute.
3.) Then the experimenter has to label the plant that the microwaved water was put in- Microwaved Water ONLY.
4.) The experimenter has to measure another 2/3 of a cup of water, but it has to be unheated water.
5.) Next, the experimenter must label the plant that was watered with unheated water- Unheated Water ONLY.
6.) Then, the experimenter must get a third plant and put it in the soil and put- Regular Tap Water ONLY.
7.) After, you must water the plant with 2/3 a cup of nonheated tap water.
8.) Repeat steps 1-5 two more times
9.) Then the experimenter repeats the watering cycle once every four days until full results are shown.
What are popular science fair projects?
A good and popular science project is nothing that yo ugly self can do !!
Why is experementing important when seeking answers to question?
Experimenting allows you to form several hypotheses about what you might find. Then, it is fun to discover the answers!
What is the independent variable being tested in an experiment?
It is the thing that changes on each measurement in an experiment.
Why is it important to accuratay record the procedures and results an experiment?
so others can repeat it and see if you did it right
