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 […]

Making and Breaking Polymers
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
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
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 […]
Polymer Activity Using Beads
A polymer is made of many monomers linked together. monomer: A single unit; a single molecule. The diagram represents a model of a polymer. While actual polymers can be made of thousands of monomers, the model shown has only eleven. The monomers in the diagram are different colors and sizes of beads on a black […]
Chia Seeds Index
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 […]
Temperature vs. Kinetic Energy
TEMPERATURE Temperature measures how hot or cold a material is. Hot materials have a higher temperature than cold materials. In the Diagram: The contents of container A has a lower temperature than the contents of container B. I know this because the temperature reading on the thermometer in container A is lower than is the […]
Astronomy Science Fair Project Ideas
Astronomy Questions for Science Projects The independent variable and a dependent variable for each question is identified. 1. As viewed from Earth, how does a celestial body’s distance from Earth affect its apparent diameter? Independent variable: distance from EarthDependent variable: apparent diameter of celestial bodies 2. How does Earth’s position in its orbit about the […]
Periodic Table Index
1. Calendar: Periodic Table of Dayshttp://wp.me/pSQZl-6skThis article is a good introduction to the periodic table. It uses a calendar to introduce periodicity–repeating patterns. 2. Dmitri Mendeleev’s Periodic Tablehttp://bit.ly/tnjuAT A follow-up article to Calendar: Periodic Table of Days. It provides history information about the origin of the periodic table of elements. Compares Mendeleev’s first arrangement of […]
Emma Does Science Project Research
This is a story about Emma, a 10-year old girl, who has to do a science fair project. Emma belongs to a Science Club. During club meetings, Ms. Janice, the club director, and Cosmo, her teen helper guide Emma as she designs and develops her science fair project. This chapter provides easy to follow directions […]
