Writing Writing a good hypothesis worksheet 3rd Almost all writing is divided into three sections:
Print What is a Hypothesis? A hypothesis is a tentative, testable answer to a scientific question. Once a hypothesis writing activity for 3rd 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. 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? As more current flows through the motor's electromagnet, the strength of the magnetic field increases, thus turning the motor faster. 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.(what is being measured) and then write your hypothesis in an “If, then” format. 1. Can reading small print cause a headache?
Hypothesis: _____ _____ 2. Does the amount of iron in the water affect plant growth? Hypothesis:_____ _____ 3. What is a Hypothesis? A hypothesis is a tentative, testable answer to a scientific question.
