Heat Traveling Through Solids

Randall Frost Ph.D. — Thu, 12 May 2016 10:40:40 GMT

All are made up of atoms or molecules that are in constant motion. As a material is heated, the atomic or molecular vibrations become larger and the temperature increases. When sufficient heat is absorbed by the material, its solid structure breaks down and the material melts. This project looks for a correlation between the ability of selected to conduct heat and a material’s density.

Examining Mass And Density Of Popped And Unpopped Popcorn

Thu, 12 May 2016 10:40:29 GMT

Mass is the amount of matter in an object. Oftentimes you can find the mass of any object using a pan balance and can be measured in grams or kilograms. Density is the amount of mass a substance has in a certain volume. An easy way to test the density of objects is by placing them in water.If an object floats, its density is less than the density of water. If the object sinks, its density is greater than the density of water. Compare the mass and density of objects.

Salinity & Water Density

Randall Frost Ph.D. — Thu, 12 May 2016 10:39:58 GMT

Cold water is denser than warm water. Water with a high salt concentration (salinity) is denser than water that has a lower salt concentration. Warmwater rises above densercolder water, and bodies of water thathave different temperatures can form layers according to their respective temperatures. Likewise, denser water with high salinity sinks below water with low salinity.How does the addition of salt to hot water affect its mixing with colder water?

Measuring Sugar in Soda

Thu, 12 May 2016 10:33:33 GMT

We all know that sugar is filled with soda, but it’s hard to see just how much is in our drink by simply reading the label. Using a scientific instrument called a hydrometer, you can find out by precisely measuring the sugar content. Technically, a hydrometer measures any solids in a liquid, but since nearly all the dissolved solids in soda is sugar, it will work for this experiment. This experiment will examine and precisely measure the amount of sugar in various sodas.

What Affect the Length of Sound?

Barry Eitel — Thu, 12 May 2016 10:33:33 GMT

Musicians are always experimenting on how to alter and manipulate different tones. Knowing how to produce a certain tone is important in composition. This experiment will measure how material and weight changes the sound decay of a note.
