Plants have two Organ Systems: the shoot system and the root system. 1. The shoot system is above ground. This system includes these organs: stems, flowers, seeds, fruit, buds, and Stems have many jobs, including supporting the plant; acting like the plant’s plumbing system, conducting water and nutrients from the roots and food in the [...]

The scientific method is the name of the process used for scientific problem solving. Research is part of this process and includes all the different ways that information can be collected. One way to do research is to read what others have written. Directions: Read the following information about gravity. Then answer the question that [...]

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 [...]

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 [...]

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 [...]

Things that vibrate send out sound waves. Characteristics of sound include, pitch, loudness, and quality. The pitch of a sound is how high or low a sound is. Pitch is basically your ears’ response to the frequency of a sound. Frequency Frequency is determined by how fast the sound producing objects vibrates. Frequency is the [...]

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. [...]

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 [...]

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 [...]

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? [...]
