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.

Sound Waves

By

 Sound is a type of energy that moves through material causing the material to vibrate. Sound is also vibrations that cause the sense of hearing. Vibrate means that a material moves back and forth or up and down. Sound energy causes a material to move back and forth in the same direction that the sound […]

Seed Parts

The diagram shows shows the inside of a pinto bean. The embryo is the part of the bean seed that develops into a bean plant. The remaining part, called the cotyledon, is the food for the developing embryo. Use the diagram to identify the following parts of the embryo. embryo –the immature plant inside a […]

Equinox vs. Solstice

By

Times of sunrise and sunset change daily throughout the year as Earth revolves around the Sun. Changes in seasons are linked to the regular changes in the hours of daylight and darkness throughout the ear. The equatorial region (tropics) between the Tropic of Cancer and the Tropic of Capricorn has about an equal amount of […]

Science Fair Projects: Topics

By

If your goal is to get an A+ on your project, win awards at the science fair, and learn many new things about science, then choose a topic that interests you. If you find after some work that your topic is not as interesting as you originally thought, if possible stop and select another one. […]

Science Fair Project: Energy

By

Hi, All of the links on this post are not working—I am in the process of correcting this problem. Janice Before you start your project, acknowledge that you are preparing an entry to a contest. Contests, whether they are associated with sports or academics have rules. Football players must follow the rules to score. Science […]

Engineering Projects

By

Engineering projects may be part of a science fair, but each has a different set of guidelines for solving problems or finding answers to questions. The process for science fair projects is called the Scientific Method. The process used to develop an engineering fair project is called the Engineering Method. These different methods stem from […]

The following guidelines are set by the International Science and Engineering Fair (ISEF). Note that these guidelines address judging of both science projects and engineering projects. This comparison gives you clues about […]

Science Fair Committees

By

Judging Committee This group invites and and notifies judges of date, time and location where they will work. Familiarizes judges with the judging criteria for the grade level they will be evaluating (a ratio of one judge per 20 projects is recommended, with three judges per project); provides judges materials, such as a clip board […]
