Science Project: Relative Density

By Janice VanCleave

Boats with the same density have the same buoyancy in water. As the density of the boats increase, the less buoyant are the boats.

How to Analyze Relative Density Data and Write a Conclusion Research: The data being analyzed below is about relative density and buoyancy. Relative density is a comparison of densities. Buoyancy refers to something floating in a fluid (gas or liquid). In the diagram, the Box-shaped boats are all floating in water. This means that each […]

How the Independent Variable of Light affect the Dependent Variable of Plant Growth

Types of Variables in A Science Fair Project Independent variables Dependent variablesControlled variables When experimenting, a variable is anything that might change and affect the results of the experiment. Examples are the best way to explain types of variables. Example: Investigate Electromagnetics 1. What is an electromagnetic?  Discover how to make an electromagnetic. This type of […]

Investigations for Science Fair Projects What is a Science Fair? What is a Science Fair Project? A science fair is a competition where you, the contestant, enter your science projects. How is a Science Fair Project Different from any other Science Project? Every science project has rules to follow. What distinguishes one science project from […]

Chia Seed Science Projects Ideas

By Janice VanCleave

How to Write a Science Project Question An Experimental Science Project is a Cause/Effect investigation. In other words, the change in one thing causes something else to change. The “Cause” part of the investigation is what you will have control over. The “Effect” part of the investigation is what you will be observing to decide […]

Science Fair Projects about Animals

By Janice VanCleave

Zoology is the study of animals and how they behave, live and survive.. FYI: Special permission is needed to work with live animals as well as parts from dead animals, including bones in designing and developing a science project. Below is a science fact about Anoles. This fact is a statement containing: one independent variable […]

Crystal Project: Variables

By Janice VanCleave

Halie Crystal

A variable is something that can change. For your science fair project, you should change one variable to see what affect it has on another variable. These two variables are: independent variable: Something that you choose to change. dependent variable: Something that changes in response to changes in the independent variable. 1. Following are ideas […]

Science Fair Project Question

By Janice VanCleave

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 […]
