ABOUT THE SOUND PICTURE

With mouth wide open, vibrating air coming up the throat from the vocal chords leaving the open mouth and spreading in all directions. Hi, I am Janice VanCleave, author of 50+ best-selling science experiment books for children ages 4 through high school. I taught science for 27 years and now am creating this science website.   My scream was not staged. The picture was to be of two adult cats, which I was holding. A microsecond before the camera snapped, the two cats dug their claws into my skin as they prepared to leap out of my arms. A picture like this is great for making inferences. Kids could make "guesses" as to why I am screaming. They would be drawing on facts from the photo, such as I look like I am in pain or maybe I am just pretending.

Science Fair Project: DNA Extraction

By

Question:

I want to do a science fair project about DNA. How do I get started?

Answer:

Following are steps to help you start a project about DNA.

Step 1. Topic

When doing a science fair project, your first step is to select a topic. You have selected the topic DNA. Since a science fair project should be an experiment, I recommend extracting DNA from plant or animal cells.

Step 2. Research

Research is learning about your topic. You can do this by reading about DNA as well as doing an exploratory investigation about DNA extraction.

Note: Exploratory Investigations are experiments, usually with step-by-step instructions.

There are different exploratory experiments about DNA extraction, but most have the basic procedure..

Note: The procedure for exploratory experiments can often be used as the Experimental Control for your science fair project. The same procedure can be used as the pattern when designing an experimental investigation for your science fair project.

Experimental Control, which is a standard that you can compare the results of your science project experiment with. More about this later.
