Your Guide to Science Fair Topics, Ideas, Experiments, and Winning Displays
Hi, I am Janice VanCleave. My goal is to create homeschool material on my website to provide ideas that will work for you. Many homeschoolers ask for ideas to expand experiments. In response to this, I have designed teaching tips that can be adapted to even the simplest experiment. But, these are just my ideas [...]
Introduction to the Science At Home Series: Project 1: Fun With Water Investigation: The Blooming of a Paper Flower Andrea Roseman, a homeschooling mom with two lovely children, tested this experiment and posted comments on her website, WhatEverPhilippians48. Andrea and I exchanged ideas and with her approval, I have included her hints, clues, and suggestions [...]
Building an Experimental Science Project Question New Science Terms cause effect controlled variables dependent variable experimental question independent variable variables An experimental question is a cause-effect question. Note: Things that can be changed or change on their own are called variables. In an experimental question, the variable that causes another variable to change [...]
Types of Variables in A Science Fair Project Independent variables Dependent variables Controlled variables A variable is part of an experiment that can change, such as amount of light, temperature, humidity, time changes, or plant growth. Independent Variable In an experiment, an independent variable is a variable that either changes on its own, or you [...]
What Are the Variables in “Float a Needle” from “Science Wizardry for Kids” by Margaret Kenda. “Floating a Needle” is an exploratory investigation about surface tension. Surface tension is the property of liquids in which the exposed surface acts as if a thin skin has been pulled across it. This property is due [...]
Variables in A Slime Experiment Variable is the name given for any part of an experiment that changes. For example, the following question identifies what is happening as well several variables which are identified. Question: If a glue solution and a borax solution are mixed, what effect would the ratio of the solutions have [...]
What are the Different Types of Experimental Variables? Variables are anything in an experiment that can change on its own or can be changed. Types of experimental variables are: independent variables, dependent variables, controlled variables. Independent Variable (IV) An independent variable is a variable that is purposely changed. The purpose of an experiment is [...]
A Science Fair Project is a cause/effect investigation. The cause is called an independent variable (something you purposely change). Changes in the independent variable effects another variable called the dependent variable. You AFFECT the investigation by making changes in the independent variable. This change EFFECTS the dependent variable causing it to change. Exploratory Experiment Rock [...]
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 [...]
Step 3: Variables (things that can change) Variable is the name given for any part of an experiment that changes. For example, the following question identifies what is happening as well several variables which are identified. Note: The Question is an example for identifying variables–but is in the form of writing a science fair project [...]
