Passive Transport

By

Passive Transport: passive: no energy is requiredtransport: to move through a cell membrane. Passive transport is the movement of molecules through a cell membrane without expending any energy. Types of Passive Transport In and Out of Cells. 1. Simple Diffusion is a passive transport in which particles pass through the plasma membrane surrounding a cell. […]

Insolation

By

Insolation is a measure of solar radiation received on a surface area in a given time period. Some of the insolation is absorbed by the material it strikes, while some of the insolation is reflected. In the diagram, each sun-ray is 1 mile wide. One sun-ray  is perpendicular (90 degrees) to the surface it strikes. […]

Protozoa

By

What is a Protozoa? Protozoa are single-celled organisms that are most likely found in stagnant water. Look for protozoa close to the edge of ponds. The word “protozoa” means first animals. Even young children can learn about protozoa. The following material was provided by Amida, a homeschooling mom. The activities for the paramecium and euglena  models shown […]

Potatoes

By

Which is the correct spelling, potato or potatoe? To this day, my brain sees the word as POT-A-TOE, just like my grandmother taught me.The same with TOM-A-TOE. Actually, I have a long list of words that I misspell no matter how many times I look at the correct spelling. After a time I seem to […]

Making and Breaking Polymers

By

What are Polymers? How are Polymers Made? How are Polymers Broken? Polymers are macromolecules, which means very large molecules. Each polymer is a chain of identical or similar  links called monomers. How are monomers linked together to form polymers? The process of linking monomers is known as condensation, or dehydration synthesis. Remember that the term […]

Free Radicals

By

Radicals are atoms or molecules that have one or more unpaired electrons. The electrons in the outer energy level of an atom are called valence electrons. The maximum number of valence electrons is eight. The diagram show models for all the possible number of valence electrons and their arrangement. The models with unpaired electrons are […]

Carbohydrates

By

Carbohydrates, also called saccharides, are organic chemicals found in plants. The two basic structures of carbohydrates are simple and complex. Simple carbohydrates are also called simple sugars and yes, they have a sweet taste.The simplistic nature of these chemicals has to do with their molecular structure. As the name implies, the structure of these molecules […]

Chia Seeds Index

By

A big thanks go to these chia companies for providing seeds as well as information for the research information on this site. 1. ChiaDirect has both small and large packages of seeds for affordable prices with no shipping fees. 2. ChiaFarms has nutritional information about feeding chia seeds to animals. Seeds are only sold in […]

Chia Seed Science Projects Ideas

How to Write a Science Project Question An Experimental Science Project is a Cause/Effect investigation. In other words, the change in one thing causes something else to change. The “Cause” part of the investigation is what you will have control over. The “Effect” part of the investigation is what you will be observing to decide […]
