How to write a good hypothesis for chemistry

Surprisingly, scientists seldom succeed in demonstrating the veracity or falsehood of a hypothesis. It allows for predictions that will occur in new circumstances.

Are these two events connected? If I add fertilizer to the soil of some tomato seedlings, but not others, then the seedlings that got fertilizer will grow taller and have more leaves than the non-fertilized ones.

Educators can also assign students an online submission form to fill out detailing the hypothesis of their science project.

If that is the case, this could constitute a hint that the same paradigm might be accurate for nicotine. Good Hypothesis Poor Hypothesis When there is less oxygen in the water, rainbow trout suffer more lice.

In the second example, the independent variable would be fertilizer type, that is to say, whether the fertilizer is organic or non-organic.

What happens if, at the end of your science project, you look at the data you have collected and you realize it does not support your hypothesis? You may find many studies similar to yours have already been conducted. Read on to learn more about this false notion.


If the plant is given water then the plant will grow the tallest because water helps the plant absorb the nutrients that the plant needs to survive. As per the examples presented above, we could formulate the following non-directional hypotheses: Putting it in Action To help demonstrate the above principles and techniques for developing and writing solid, specific, and testable hypotheses, Sandra and Kristin, two of our staff scientists, offer the following good and bad examples.

A Strong Hypothesis

Included the independent and dependent variables in the hypothesis statement. You should also be able to repeat your experiment over and over again, if necessary.

A single hypothesis can lead to multiple predictions, but generally, one or two predictions is enough to tackle for a science fair project.

Nevertheless, a hypothesis can also represent an assertion that reports a discovered natural model, which is known as a generalizing hypothesis.

A Strong Hypothesis

This particular type of assertion is referred to as an explanatory hypothesis. The response you suggest constitutes your explanatory hypothesis. School students may also ask their teachers, librarians or fellow-students to assist them. Or, as it is sometimes put, to find out the scientific truth.

The response you suggest constitutes your explanatory hypothesis. Analyzing such questions offers you a great opportunity of standing out by covering substantial holes in an area of research.Scientific Hypothesis Examples.

What Makes a Good Hypothesis? (With Examples) Know the Steps of the Scientific Method. Hypothesis: Cats do not show a paw preference (cat equivalent to being right- or left-handed).

You could gather data about the number of times cats bat at a toy with either paw and analyze the data to determine whether cats, on the whole, favor one paw over the other. A hypothesis is a prediction of the outcome of a test.

It forms the basis for designing an experiment in the scientific method.A good hypothesis is testable, meaning it makes a prediction you can check with observation or testing. Research Hypothesis Examples A research hypothesis (H 1) is a type of hypothesis used to design an experiment.

This type of hypothesis is often written as an if-then statement because it’s easy to identify the independent and dependent variables and see how one affects the other.

Oct 30,  · To write a good lab conclusion in science, start with restating the lab experiment by describing the assignment. Next, explain what you were trying to discover or figure out by doing the experiment.

Then, list your results and explain how they confirmed or did not confirm your hypothesis%(). Sep 08,  · Expert Reviewed. How to Write a Good Lab Conclusion in Science.
