Phenotype vs. Genotype

By Janice VanCleave

The difference between Inherited physical characteristics and learned behavior;phenotypes.

Phenotype is the outward physical manifestation of an organisms (living things) determined by the genotype, which is the  internally coded, inheritable, information called DNA. The dog has long pink hair. Having long hair is a phenotype, but the pink coloring is a dye. The dog’s natural hair color is white. All phenotypes are inherited and […]

Insects: Water Striders

By Janice VanCleave

What Characteristics Identify Water Striders as Insects? Insects have many different shapes, sizes, and weights. Some, like the water strider in the video, can stand and move across the water from 3 to nearly 5 feet per second. The video is in slow motion. Like all insects, water striders have three pairs of legs and […]

Tips for Homeschool Science

By Janice VanCleave

The insect model is of a water strider. Surface tension as well as physical structures of the insect affect the insect's ability to float on the water.

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 […]
