Most science fairs have similar point systems for judging science fair projects. I would instruct judges to consider every project average before even seeing them. Using a scoring system of 1 to 5, with 1 being the lowest point, then 3 would be average. As each judge evaluates a project, he or she decides if […]
Scientific Method: Color Changes
Research: Paints contain materials called pigments or colorants. These materials produce colors by reflecting certain colors of light. The three primary colors for paints are Red, Blue, and Yellow. The mixing of any two of these colors produce what are called secondary colors. Red + Blue= Purple Red + Yellow = Orange Blue + Yellow […]
Browning Apple: Data Analysis
How to Create a Comparative Color Scale Your experiment is over and data has been collected. You now want to study your data results and make comparisons between the independent variable and the dependent variable. For the example project, a color scale can be created in order to have quantitative information to describe the results. […]
Browning Apple: Control
An Experimental Control To conduct a scientific investigation, care must be taken to follow experimental procedures. You must design an experiment to test your hypothesis. When planning your experiment remember to: 1. Keep everything the same except for the single variable being tested, which is the INDEPENDENT VARIABLE:. A variable is something that can be […]
Browning Apple: Data
Collecting data is a very important part of your project. As a reminder, DATA is recorded information. It is the results of your experiment. Data for this example project includes your observations of the apple slices. This can be written observation as well as diagrams. Clue:It is difficult to remember exactly how things look when […]
Browning Apple: Hypothesis
If your science fair project question is: What effect does the type of citric fruit covering apple slices have on their browning ? Your hypothesis will be your idea about the answer to your science fair project question. A hypothesis is basically your educated guess. A hypothesis is your prediction about the results of the […]
Browning Apple: Experiment
A science fair project experiment must test the accuracy of the hypothesis. For this example science fair project the example question and hypothesis are: Question: What effect does the type of citric fruit covering apple slices have on their browning ? Hypothesis: Since all citric fruits contain citric acid, any kind of citric fruit covering […]
Apple Slice With Star
Dried apples have unusual, but very interesting characteristics. Discover For Yourself Ask an adult to cut an apple in half, cutting across the apple as shown in the diagram. 1. Allow one-half of the apple to dry. Place the apple piece near a window so that it receives direct sunlight if possible. Place something, such […]
Browning Apple: Question
Science Fair Project Question Observation: Sliced apples turn brown. Getting Started: If citric acid in lemons prevents sliced apples from browning, would other types of acid do the same thing? Purpose: To determine if different types of acid prevent sliced apples from turning brown. Two things are changing: 1. Type of acid used—You control this […]
A Camel’s Adaptive Characteristic
Question: How do animals adapt to their environment? Answer: I do not support the idea that animals purposely change their bodies over time so that they can better adapt to an environment. Instead, I support the idea that animals that have certain physical characteristics are better adaptive to an environment. For Example: Camels can survive […]
