The format should be I think choose an independent variable will affect on the dependent variable. Which ball will go the farthest 2. We make an "educated guess.
Our next step is to write a hypothesis. I think that the mercury will destroy it the fastest. How will the three different sodas effect the weight of the nail?
My problem statement is Which liquid will make the plant grow tallest? I think the 6 cups of water in the container with the highlitghter will be shown at a further distance.
KoreyW Which fruit juice will ferment the most? The variables in this experiment are the soap and the food coloring. Revise the hypothesis if you wish to give the experiment more depth.
Included the independent and dependent variables in the hypothesis statement. What is a hypothesis? People say that they have theories about different situations and problems that occur in their lives but a theory implies that there has been much data to support the explanation.
If I add fertilizer to my garden, then my plants will grow faster. Staff Scientist Dave reminds that scientific experiments become a dialogue between and among scientists and that hypotheses are rarely if ever "eternal.
It builds upon previously accumulated knowledge e. A look at the work of Sir Isaac Newton and Albert Einstein, more than years apart, shows good hypothesis-writing in action.
Well, your data "supported" your hypothesis, but your experiment did not cover that much ground. It is helpful for students to observe how food coloring acts in water, milk and oil before they attempt to write a hypothesis.
What is your hypothesis? Would adding salt make a difference? Examples of Hypotheses and Predictions Question Prediction How does the size of a dog affect how much food it eats? Hypothesis- I predict the amount of the air will change the bounciness of the ball. Which is why scientists only support or not their hypothesis with data, rather than proving them.
Print What is a Hypothesis? For example someone performing experiments on plant growth might report this hypothesis: Most people would agree with the hypothesis that: How will the number of worms effect the growth of 3 plants in one week with the same amount of sunlight and water.
How long would it take tap to fill up apicher. Start by finding some information about how and why water melts. Which plant will grow the tallest in a one week period with the same amount of light and greywater?
Food coloring, which dissipates in water, is held in place by the fat and protein in the milk.
Make sure your hypothesis is a specific statement relating to a single experiment. My problem is what will cool a soda faster a refrigerator or freezer.
Does that seem like an educated guess? I believe that the Heafty brand will hold 30 pounds of rocks for the longest amout of time.
It is worth noting, scientists never talk about their hypothesis being "right" or "wrong. Or, as it is sometimes put, to find out the scientific truth.
If I never water my plant, it will dry out and die. If I let a pound dog and a pound dog eat as much food as they want, then the pound dog will eat more than the pound dog.
I think the number of rubber bands will effect the distance of the shot ping pong balls.
Which gum lasts the longest? The dish soap disrupts the chemical bonds that hold them in solution because it forms a bond with the fat. I think the face shot will be the most accurate.You'll also find that in order to write a solid hypothesis, you need to understand what your variables are for your project.
It's all connected! If I never water my plant, it will dry out and die. That seems like an obvious statement, right? The above hypothesis is too simplistic for most middle- to upper-grade science projects, however.
Now that you know your independent and dependent variable, the rest of the science fair project is a piece of cake. Your problem statement and hypothesis are extremely easy to write if you have determined your independent and dependent variables.
Writing a science fair project report may seem like a challenging task, but it is not as difficult as it first appears. This is a format that you may use to write a science project report. This is a format that you may use to write a science project report. Now it's time to run the experiment to support the hypothesis.
A hypothesis isn't an educated guess. It is a tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation. Once you do the experiment and find out if it supports the hypothesis, it becomes part of scientific theory.
Revise the hypothesis if you wish to give the experiment more depth. A more formal hypothesis thinks in terms of how the variables are related to each other. If soap can make food coloring mix with milk, then adding more soap to the milk in different places will cause the food coloring to mix with the milk faster.
Predictions should include both an independent variable (the factor you change in an experiment) and a dependent variable (the factor you observe or measure in an experiment). A single hypothesis can lead to multiple predictions, but generally, one or two predictions is enough to tackle for a science fair project.Download
