Seed:Dissection

By

To discover what is inside a seed, pinto beans, which is a seed, can be dissected. Following are steps that can be used to observe the different parts of a seed. Note: While the diagrams show the water and beans to be green. Actually, the beans should be brown and the water clear. 1. Place […]

Adhesion Project:Hypothesis

By

Step 5: Hypothesis A hypothesis is your guess about the answer to your project question. This is not a “wild” guess. You need to have a good reason for the hypothesis you state. Please know that I made up all of the following hypothesis. They may or may not be true. They are examples for […]

Dwarf Planets

By

Most asteroids are irregular, rocky chunks of matter which orbit the Sun. Until 2006, Ceres was considered to be the largest asteroid with a diameter of about 600 miles (960 km). It was not its size that changed its classification, instead other physical features were the deciding factors that boosted the hunk of rock into […]

Crystalline Solids

By

Crystalline solids are solids made of crystals. Crystals are solids with flat surfaces. Crystals are made of chemicals arranged in a regular, repeating pattern. Crystals are made of chemicals that fit together much like a puzzle. The shape of a crystal depends on the shape of the chemical building blocks that it is made of. […]

Gold Isotopes

By

Atoms are the smallest particle of an element that retains the characteristics of the element. For Example: The gold nugget in the diagram is made up of individual gold atoms. Gold Atom Diagram The circle represents the nucleus of a gold atom. Outside the nucleus of the gold atom are 79 electrons (negative charges). Electrons […]

Moon-Disk Rotation

By

The Moon’s landscape causes shadows which creates a pattern. Some say the shadows form a shape like a person, thus they refer to the shadows as the “Man in the Moon.” Observe the photo of the Moon shown. Do you see any particular shape formed by the shadows? The shadows never looked like a man […]

Crystal Project: Hypothesis

By

A hypothesis is your best prediction about the answer to your science fair project question. The science fair project question is: How does the type of dissolved salt effect the appearance of the evaporite crystals formed? So, what do you think? Will using different kinds of salt affect the physical appearance of the crystals formed? […]

Thomas Edison’s Childhood

By

Thomas Alva Edison (1847-1931) was born in Milan, Ohio. He was the seventh and last child of Samuel Edison, Jr. and Nancy Elliot Edison. His mother was a former schoolteacher; his father had no specific training and was considered a jack-of-all-trades, meaning he could do many different kinds of jobs. When Thomas was seven, his […]
