How to write a scientific report for kids

History of science Science in a broad sense existed before the modern era and in many historical civilizations. In particular, it was the type of knowledge which people can communicate to each other and share.

Print What is a Hypothesis? A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic.

Then she uses that information to form a tentative answer to her scientific question. Sometimes people refer to the tentative answer as "an educated guess.

A hypothesis leads to one or more predictions that can be tested by experimenting.

This means that we don't use parts of other papers or duplicate content whatsoever.

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.

Examples of Hypotheses and Predictions Question Prediction How does the size of a dog affect how much food it eats?

Larger animals of the same species expend more energy than smaller animals of the same type. To get the energy their bodies need, the larger animals eat more food. 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.

Does fertilizer make a plant grow bigger? Plants need many types of nutrients to grow. Fertilizer adds those nutrients to the soil, thus allowing plants to grow more.

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. Does an electric motor turn faster if you increase the current? If I increase the current supplied to an electric motor, then the RPMs revolutions per minute of the motor will increase.

Is a classroom noisier when the teacher leaves the room? Teachers have rules about when to talk in the classroom. If they leave the classroom, the students feel free to break the rules and talk more, making the room nosier. If I measure the noise level in a classroom when a teacher is in it and when she leaves the room, then I will see that the noise level is higher when my teacher is not in my classroom.

What if My Hypothesis is Wrong? 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? First, do not panic! The point of a science project is not to prove your hypothesis right.

The point is to understand more about how the natural world works. Or, as it is sometimes put, to find out the scientific truth. When scientists do an experiment, they very often have data that shows their starting hypothesis was wrong.

Well, the natural world is complex—it takes a lot of experimenting to figure out how it works—and the more explanations you test, the closer you get to figuring out the truth.

For scientists, disproving a hypothesis still means they gained important information, and they can use that information to make their next hypothesis even better.

In a science fair setting, judges can be just as impressed by projects that start out with a faulty hypothesis; what matters more is whether you understood your science fair project, had a well-controlled experiment, and have ideas about what you would do next to improve your project if you had more time.

It is worth noting, scientists never talk about their hypothesis being "right" or "wrong. This goes back to the point that nature is complex—so complex that it takes more than a single experiment to figure it all out because a single experiment could give you misleading data. For example, let us say that you hypothesize that earthworms do not exist in places that have very cold winters because it is too cold for them to survive.

You then predict that you will find earthworms in the dirt in Florida, which has warm winters, but not Alaska, which has cold winters. When you go and dig a 3-foot by 3-foot-wide and 1-foot-deep hole in the dirt in those two states, you discover Floridian earthworms, but not Alaskan ones.

So, was your hypothesis right?Although the main headings are standard for many scientific fields, details may vary; check with your instructor, or, if submitting an article to a journal, refer to the instructions to authors.

When student scientists engage in scientific experiments, they convey their results through the composition of a experiment report. This report consists of a number of standard elements. As kids learn to use the scientific method to discover the world around them, keep in mind that the goal of a science report is to explore what exactly the student learned during the experiment.

Writing a Hypothesis for Your Science Fair Project

Write down what you hope to prove in your experiment. Unlike an essay, a report has a formalised structure. Taking into account disciplinary differences, scientific or laboratory reports written by undergraduates share the same format as scientific reports written by academics for publication.
