In the world around us there are many examples of vortexes: tornadoes, whirlpools in a sink or tub, swirling vortexes in rivers and oceans and, of course, hurricanes. You can make your own vortex to do experiments with. For this you will need two empty plastic soda bottles (with the labels removed), duct tape, and […]
Vortex Bottle
You can create a vortex by stirring a oit of water with a spoon. But a vortex bottle provides the opportunity to investigate different variables. You can construct your own vortex bottle using instructions here: VORTEX BOTTLE 1. Making the vortex bottle is part of your research. Other things to research would be to read […]
Science Fair Ideas
I WILL BE ADDED NEW IDEAS TO THE FOLLOWING LISTS, SO STOP BACK PERIODICALLY FOR MORE IDEAS. JANICE Ideas for developing Science Models Astronomy 1. What is a solar eclipse? You could show diagrams of the position of the Sun and Earth during a solar eclipse. Diagrams of how to safely observe a solar eclipse […]
How Fingerprints Differ
Fingerprints Zoology is a study about people and animals. Fingerprints are grooved patterns on the tips of the fingers. Everyone’s fingerprints are different, so they can be used for identification. Zoology Project Ideas Purpose: To discover how these variables affect fingerprint patterns: * Different fingers on the same hand. * Fingers on right and left […]

A Science Project About DNA Extraction A science project is a special type of investigation. It could be said that it is a proposed, contemplated, and planned type of investigation with the purpose of testing or discovering scientific knowledge. For more details, see What is a Science Project? In reference to a science project, […]
Science Fair Project Data Collection
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 use numbers to measures to describe the results. The scale shown indicates different colors […]
Science Project Experiment
Browning Apple Project 1. Research 2. Question 3. Hypothesis 4. Experiment A science fair project experiment must test the accuracy of your hypothesis. For this example science fair project the example question and hypothesis are: Question: What effect do different types of citric fruit have on preventing apple slices from browning? Hypothesis: Since all citric […]
