lab report hypothesis example

Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen. Make it clear. A good hypothesis is written in clear and simple language. Reading your hypothesis should tell a teacher or judge exactly what you thought was going to happen when you started your project. SAMPLE LAB REPORT. The Optimal Foraging Theory: Food Selection in Beavers Based on Tree Species, Size, and Distance Laboratory 1, Ecology Abstract. The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. A scientific lab report is simply a paper that explains to an audience an experiment that was done in order to support a hypothesis or null-hypothesis. Lab reports are common in the scientific community and can become published in accredited scientific journals after peer review. Lab reports can Author: Laura Writes.


Lab report hypothesis - The Writing Center.


Sound familiar? It should. This formulaic approach to making a statement about what you "think" will happen is the basis of most science fair projects and much scientific exploration. Following the scientific methodwe come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify what we "think" will happen.

What you "think" will happen, of course, should be based on your preliminary research and your understanding of the science and scientific principles involved in your proposed experiment or study. In other words, you don't simply "guess. You're not pulling your statement out of thin air. Instead, you make an "educated guess" based on what you already know and what you have already learned from your research.

If you keep in mind the format of a well-constructed hypothesis, you should find that writing your hypothesis is not difficult to do. 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! That seems like an obvious statement, right? The above hypothesis is too simplistic for most middle- to upper-grade science projects, however.

As you work on deciding what question you will explore, you should be looking for something for which the answer is not already obvious or already known to you. When you write your hypothesis, it should be based on your "educated guess" not on known data. Similarly, the hypothesis should be written before you begin your experimental procedures—not after the fact.

Keep in mind that writing the hypothesis is an early step in the process of doing a science project. The steps below form the basic outline of the Scientific Method :. 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. When there is less oxygen in the water, rainbow trout suffer more lice. Kristin says: "This hypothesis is good because it is testable, simple, written as a statement, and establishes the participants troutvariables oxygen in water, and numbers of liceand predicts effect as oxygen levels go down, the numbers lab report hypothesis example lice go up.

Our universe is surrounded by another, lab report hypothesis example, larger universe, with which we can have absolutely no contact. Kristin says: "This statement may or may not be true, but it is not a scientific hypothesis. By its very nature, it is not testable. There are no lab report hypothesis example that a scientist can make to tell whether or not the hypothesis is correct.

This statement is speculation, not a hypothesis. Aphid-infected plants that are exposed to ladybugs will have fewer aphids after a week than aphid-infected plants which are left untreated. Sandra says: "This hypothesis gives a clear lab report hypothesis example of what is to be tested the ability of ladybugs to curb an aphid infestationis a manageable size for a single experiment, lab report hypothesis example, mentions the independent variable ladybugs and the dependent variable number of aphidsand predicts the effect exposure to ladybugs reduces the number of aphids.

Ladybugs are a good natural pesticide for treating aphid infected plants. Sandra says: "This statement is not 'bite size.

There is no clear indication of what will be measured to evaluate the prediction. Throughout history, lab report hypothesis example, scientists have posed hypotheses and then set out to prove or disprove them. Staff Scientist Dave reminds that scientific experiments become a dialogue between and among scientists and that hypotheses are rarely if ever "eternal.

A look at the work of Sir Isaac Newton and Albert Einstein, more than years apart, shows good hypothesis-writing in action. As Dave explains, "A lab report hypothesis example is a possible explanation for something that is observed in nature. For example, it is a common observation that lab report hypothesis example that are thrown into the air fall toward the earth.

Sir Isaac Newton put forth a hypothesis to explain this observation, which might be stated as 'objects with mass attract each other through a gravitational field. Newton's hypothesis demonstrates the techniques for writing a good hypothesis: It is testable. It is simple. It is universal. It allows for predictions that will occur in new circumstances. It builds upon previously accumulated knowledge e.

Like Newton's hypothesis, the one offered by Einstein has all of the characteristics of a good hypothesis. That's good news for scientists of all ages.

There are always questions to answer and educated guesses to make! Good Hypothesis Poor Hypothesis When there is less oxygen in the water, rainbow trout suffer more lice. Categories: Tips and Tricks. Read These Next August 16, Explore Our Science Videos.
