frequency (how often something happens).For your DEPENDENT VARIABLE (must be quantitative), you could measure….Find something to measure: You must measure something! Think about all the things you can measure:.In all cases the independent variable (aka manipulated or explanatory variable) is the one you will manipulate (pumpkin weight, pumpkin volume, pepper size) and the dependent variable (aka response variable) is the one you will measure (number of seeds inside, size of seeds inside) in your experiment(s). What is the effect of jalapeño pepper size on the number of seeds inside?.What is the effect of pumpkin size on the average size of the seeds inside?.What is the effect of pumpkin volume on the number of seeds inside?.For example: if the project was “what is the effect of pumpkin size (weight) on the number of seeds inside?” you could make an original project by asking any (or all) of the following questions: For your original project, you will need to change something about the one you found. Complete the project as it is because this is a good way to learn the scientific method. Find directions for a project online or in a science fair project book.This is unquestionably the hardest part, so here are 3 strategies for finding an original idea, ranked from easiest (good enough) to hardest (best): Repeat steps 2-5 for as long as you have time, resources, and interest. STEP 5: Ask a new question, based on the results.STEP 4: Analyze the data to determine if the prediction should be accepted or rejected.STEP 3: Design an experiment to generate data to test the hypothesis (easier than it sounds).
STEP 2: Predict the answer to the question (we call that prediction a hypothesis).STEP 1: Based on observations, ask a question.The key to a successful project is combining the correct use of scientific method with an original idea.įirst, learn the basics of the scientific method A science fair project involves conducting an experiment to answer a question or solve a problem. It is also different from making a model such as a volcano or solar system. The first you thing you need to know is that a science fair project is different from a school report on a special topic like whales, planets, or climate change. Is a looming science fair project keeping you up at night? Has the teacher sent home an “informational packet” that requires your child to bring back a completed project? Does the teacher’s kid win the school fair every year anyway? Fear not – help is here! I have launched a new (and free) website/blog to help parents help kids complete exciting, enjoyable, and technically correct science fair projects – even if it is due… tomorrow.
