...scientific method. However, the scientific method steps detailed below describe the main steps that scientists commonly take when conducting a scientific inquiry. THE SCIENTIFIC METHOD HAS FIVE STEPS: 1. Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment. 2. Ask a question, the purpose of the question is to narrow the focus of the inquiry, to identify the problem in specific terms 3. Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation. 4. Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis,...

...Observation is the first stage in understanding the problem you have chosen. After you decide on your area of science and the specific question you want to ask, you will need to research everything that you can find about the problem. You can collect information on your science fair topic from your own experiences, books, the internet, or even smaller "unofficial" experiments. This initial research should play a big part in the science fair idea that you finally choose. I enjoy gardening, and I noticed that some tomatoes are bigger than others and I wonder why. I decide to learn more about what makes plants grow. In this stage of the experiment I decide to use as many sources as I can find. The more information I have on the scientific experiment, the better the design of my experiment is going to be. Hypothesis is the next stage of the Scientific Method is known as the "hypothesis." This word basically means "a possible solution to a problem, based on knowledge and research." The hypothesis is a simple statement that defines what you think the outcome of your experiment will be. All of the first stage of the Scientific Method -- the observation, or research stage -- is designed to help you express a problem in a single question ("Does the amount of sunlight in a garden affect tomato size?") and propose an answer to the question based on what you know. The experiment that you will design is done to test the hypothesis. Topic: Does the amount of sunlight a tomato plant receive...

...By Samirah DeVoise For this year’s science fair project I’ve decided to do my topic on how the type of dog may affect how loud its bark is. The primary reason why I selected this topic is because a recent project has intrigued me to broaden my knowledge in animal science. Since my science fair project is on how the type of dog may affect how loud its bark is. I predicted that the bigger dog breed would have the loudest bark because big dogs have deeper barks. As for the smaller dog breed I predicted that they would have a higher bark because of the shape of their vocal chords and their pitch, not the volume. After comparing the smaller breed to the bigger breed I finally came up with a hypothesis. My hypothesis is if I test different breeds of dogs, then, the bigger breed will bark the loudest because the big dogs have deeper barks. For my experiment, I chose four different test subjects (dogs) all of different breeds. Before I began my experiment I asked each pet owner for permission to use their pet in my experiment. Once I was given permission to use each pet owner’s dog, I started to collect all of the equipment I needed to begin my experiment. Then I started to test each test subject with the same four variables. While testing each test subject I recorded each trial with a decibel meter to determine the sound level of each test subject (dogs). While doing my experiment I noticed that my research was getting me closer to having my hypothesis being correct. I believe...

...Joanna Antonopoulos Love hate relationship. That’s how I would describe my relationship with science. I can’t recall the first in class science experiment I did in school, but towards the end of 5th grade, I ran against other 5th graders in a science fair and the objective was to build your own experiment and use the scientific method. Well, I decided to do an experiment on what water can conduct electricity so I took 3 different types of water: such as: distilled, tap, and undistalled water. With those 3 different waters, I put the lightbulb wires in the water and only the distilled water was able to conduct electricity. I wish the schools I went to, payed more attention to science rather than art. I feel like it would have been...

...My first post I explained what my science fair project is. I am showing the effects of erosion and what makes erosion move quickly and how to slow it down. I have started working on the project and putting it together. I have the materials all together and some parts started. I asked for some of my friends help to drink some soda out of 2-liter bottles so that I can use that for my project. I am now waiting on those bottles and my friends are almost done with their soda. I am hoping to gather all of the bottles by tomorrow. Once I have the bottles I will be able to put in some plants that I got along with set up the display to hold the bottles. I have gotten the trifold and have been working on what will be going on that. I do need to go over...

...noticing any changes that we see in the shells. After four days, very carefully, using plastic spoons, remove the eggs from the cups and lay them onto a couple layers of paper towels in order to drain. We'll notice a waxy looking coating on the eggs, but no more shell. Starting at about 2 inches high, drop an egg onto a tabletop or other surface, and watch it bounce. Working in increments of 1 inch, drop the egg from increasing elevations, having our friends do the same if we conducted this experiment with others. Whoever has the egg that survives a drop from the highest height, wins. I was researching topics for science fair. Suddenly, I came out an idea in my mind was my science teacher told us that we could make the eggshell disappear. Therefore, I started to look for others’ experiments about this topic. I found out that there are some differences of the results by using different kinds of vinegar. I thought this might be an interesting science fair project so I decided to do this experiment. In conclusion, I had lots of fun by doing this project because I...

...rock salt I use on my driveway negatively affect lawns Name: Date: Assignment: Unit 1 Individual project Does the rock salt used as ice melt on my driveway effect my lawns growth? Introduction: Being from Ma cold climate, We tend to have rather harsh winters, Ice melt in some sodium form or other is regularly used to de-ice walkways and driveways. When comparing different products available, most ingredients include Sodium Chloride or Calcium Chloride. Salt, lowers the freezing temperature of water, thereby making it more difficult to refreeze. Often times, you find dead grass along the walkways and sidewalks after winter, some people attribute this to the ice melt used. Do rock salt and other deicers negatively affect lawns? That is what we will answer in this paper. Hypothesis: Grass is negatively affected by use of ice melting products, due to the sodium. Prediction: If rock salt and other ice melt products are over used, it will negatively affect the lawn by burning the grass, and causing some of it to die. Controlled Experimental Method: Because it is winter here in Montana, and doing this experiment outside on my lawn would present far too many variables, I researched ways of conducting this experiment with minimal amount of variables. Dr. Muriel Gerhard did a similar experiment for kids and posted her methods on the website education.com. I based my methods for this experiment on her experiment. I purchased good...

...Hanging With Hair Saginaw County Science Fair 2009 5th Grade Connor Blue Abstract The purpose of this project was to find out if there is a difference in the strength of different types of hair. I wanted to see if color or chemicals made a difference. My hypothesis was that blonde hair was stronger than brown hair and chemically treated hair. Individual strands of hair were collected from 30 female subjects. I tied one end to a hair hanging device and the other to a baggie. I added pennies into the bag until the strands broke, which is how I determined their strength. My testing showed that brown hair was the strongest and held an average of 27.9 pennies. Chemically treated hair held an average of 14.9 pennies and blonde hair an average of 9.9 pennies. From this research, I found that if you want strong hair, you should not get it chemically treated.

...egg shells (Plant A). We then put the egg shells, banana skin and lemon peels on the different plants as shown further up. Every day we watered the plants 60ml of water in each plant with a measuring cup. In order for the experiment to be fair we gave the plants the same amount of soil, water and sun. Our pots we used were plastic with a saucer underneath. In the control we just planted a bean, like the other pot plants. We just gave it same amount of water and sun as the others but no (nutrients) [lemon skin; banana peels and egg shells]. To make this test fair, we put all the plants in the same spot and gave them the same amount of water and sunlight. Every day we measured the plants with a metric ruler and put the measurement in the table that we made. After that, we watched carefully and observed the growth of the plant with nutrients compared to the control with no nutrients in it. Apparatus 1. 5 pots(plastic) + 5 saucers 2.

...Sentence (An analysis of American mal-practice stemming from the Henrietta Lacks story) Testing with possible death sentence We can perceive past and future medical advancement through two very different lenses. One lens is clean and colorful and paints an innovative and hopeful picture of the present and future, and therefore many folks enjoy looking through it and broadcasting it. The second is foggy, dirty and colorless, and depicts a sad and appalling look at a frightening past. This perception threatens us, as the haunting past often does. Needless to say, most people choose not to look the old lens and is rather kept occult. This is probably the reason that aside from bits and pieces of unethical experiments in our part of the world, I was simply not well-educated on the subject and never expected to hear about so many terrible incidents catalyzed by one patient’s cells. The historic lens shows us that “historically, the health care institution has failed, humiliated and ruined lives in the effort to improve medicine” (Robbennolt, 2009) , and it is important for us as social workers to look through that gloomy, grim lens and envision interventions that would have prevented it from becoming so. In a twisted irony of life, one woman’s ill fate, gave way to many discoveries that have saved many lives, but unfortunately at a heavy price for others. One such story involves a virologist named Charles Southam. The man I call the “The cancer needle...

...| | | | | Ice Melting Experiment and Analysis | INT1 Natural Science Task 3 | Ice Melting Experiment and Analysis ------------------------------------------------- Objective The objective of this experiment is to test the melting point of ice against different variables. I will use a control of ice against air and test this next to ice in water, sugar on ice, salt on ice and Baking Soda on ice. By measuring the melting time of each element on an ice cube I will be able to tell which element affects ice’s melting properties at what rate. Everyday we use chemical mixtures to melt ice that affects our roadways. A lot of these chemical mixtures are harmful to our waterways, and can pollute the environment. I believe its important to look for alternatives that can both help our roads from freezing in the winter while being kind to the environment. Industry Literature Review There are many different chemicals used in commercial ice melters that are made for our roads. Commercial companies tend to test for what elements melt ice the fastest, thus, producing a “best working” product. It is the pressure from consumers that encourages companies to test for possible harmful effects on the environment by these products, and what is most environmentally friendly. Ossain Inc. serves customers word wide with products designed around different needs for the type of ice melter needed. Their opinion on the ice melting industry is that the majority of ice melting...
