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.

Plant Root Systems

By Janice VanCleave

Taproot System: The dandelion plant has a tap root system, which consists of a main root that grows straight down. This root is much larger than the roots branching from it. The smaller branching roots are called rootlets, and these roots grow laterally. Plants with a tap root are difficult to transplant. When you pull […]

Geotropism

Geotropism

Upside Down Planter There is a special Planter advertised on TV that allows you to grow a tomato plant upside down. I wondered how successful this would be and designed a planter. The planters shown were designed by Amida and her sons. When potted, the stem and leaves of the small tomato plant were pushed […]

How Do Flies Eat?

By Janice VanCleave

Flies have a special mouth part called a proboscis. Much like the way the boy in the photo is using a straw, a fly uses its proboscis to drink liquids. Since flies do not have teeth, can they eat solid foods? Yes, and it really is gross, so get prepared: Flies vomit their stomach contents […]

Eukaryotic Cells: Plasma Membrane

By Janice VanCleave

Both animal and plant cells are eukaryotic cells (cells that contain a nucleus). All eukaryotic cells are surrounded by a plasma membrane. This membrane is also called the cell membrane. The plasma membrane is much like a thin plastic  sack with tiny hole. This membrane sack contains all the cell parts and fluids. Since there […]
