Book: A+ Chemistry Projects
The A+ in the title of this book lets you know that the content is enriched. The Experiments are easy and require materials you can purchase at a local store. If I’ve asked for something that may no longer be available, let me know and I will give you the next best substitute. Contact me […]
DNA: Project Variables
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 […]
DNA: Project Hypothesis
Step 5 Hypothesis Let’s assume that your science project question is: So, what do you think? Will using different kinds of fruit affect the amount of DNA extracted from the fruit cells? Your guess about the answer is called your hypothesis, and it should be more than just a wild guess. Instead, your hypothesis should […]
DNA: Project Questions
Step 4: Project Questions A science fair project question should identify two variables: the independent variable the dependent variable. Example Questions for the DNA Discovery Investigation 1. The dependent variables are in red type. This variable can usually be identified from the purpose of the research Discovery Investigation. For the DNA Discovery Investigation, the purpose […]
DNA Index: Extracting DNA from Food
How to Follow the Scientific Method to Develop a Science Project using an Exploratory DNA Food Extraction Investigation. I’VE PUT THE FOLLOWING IN A BASIC ORDER, BUT SOME OF THE PAGES MAY HAVE MISSING ILLUSTRATIONS. KNOW THAT I AM WORKING ON THIS. SO–REFRESH YOUR PAGE PERIODICALLY TO GET THE MOST UPDATED INFORMATION. LET ME KNOW […]
Fruit vs. Vegetables
A fruit the the part of a plant that contains seeds. Fruits have a fleshy covering around seeds. Fruit with one or more seeds inside are made by flowers. Pumpkins, apples, and tomatoes are examples of fruit. Each has seeds inside that can grow into new plants Vegetables, such as lettuce, turnips, and carrots are […]
Enriched Chemistry Project Ideas
Janice VanCleave’s A+ Projects in Chemistry Are you having a hard time coming up with a good idea for the science fair? Do you want to earn extra credit in your chemistry class? Or do you just want to know how the world really works? Janice VanCleave’s A+ Projects in Chemistry can help you, and […]
Science Project Experimental Variables
Types of Variables: Guide to the Best Science Fair Projects Independent variables Dependent variables Controlled variables Facts: 1. A variable is part of an experiment that can change, such as amount of light, or plant growth. 2. In an experiment, an independent variable either changes on its own, or you purposely change it. For example, […]
Why Glass is Transparent to Visible Light
In order to see anything, light must enter and be absorbed by the special light sensitive cells inside your eyes. These special cells called cones and rods are only sensitive to visible light, which are electromagnetic waves with wavelengths from 380 nm to 740 nm. While the term light is commonly thought to mean visible […]
