The story of potato chips dates back to late 1850s‚ when a New York chef presented deep fried crisp potato chips to the railroad tycoon Cornelius Vanderbilt. Although the invention was made out of curiosity‚ it became an instant hit after Vanderbilt gave it an approval. Till date‚ potato chips are one of the most favorite snacks among many Americans. To keep up with the healthy trend at present‚ many chips makers now have baked alternatives to traditional chips. Here are few choices of our top chips

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

which came from the potato juice. The function of an enzyme is to catalyze reactions in cells. The specific function of the enzyme in this experiment was to see if it affected the activity if it was exposed to different temperatures. A substrate is a material or substance which the enzyme acts. The substrate in our lab was hydrogen peroxide. Procedure For our experiment we used‚ three test tubes‚ nine milliliters of potato

movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent‚ each containing different concentration levels‚ then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell‚ but there is no net diffusion of water. Water

The litmus paper and the pH probe determined the salt solutions’ pH levels. When the blue litmus paper was dipped into ammonium chloride‚ the paper was changed to red whereas the red litmus paper stayed the same indicating that the solution was acidic. PH levels shown through pH probe also ranged between 5.5 to 6.0. Yet when in the presence of sodium acetate blue litmus stayed blue whereas red litmus turned blue‚ indicating its basicity. pH probe also showed the solution’s pH varied between the

of purified water again. Due to the people of the United States drinking billions of gallons of water daily‚ the amount of purified water we drink is starting to run out which is causing a problem already. Psychological studies have shown humans still don’t accept water being reused even after knowing the water is purified and perfectly clean. Advocates are still against ultraviolet machines being used to clean and purify water. While some people believe that drinking recycled water is both repulsive

Although drowning restricts one’s breathing‚ drowning in freshwater‚ and drowning in salt water will react in the body in two completely different ways (Helmenstine‚ “Drowning in Freshwater). The simple difference whenever it comes to drowning in salt or fresh water is whether the lungs are filled with a hypertonic or hypotonic solution. When drowning in freshwater‚ the water is considered hypotonic‚ meaning when water enters the cell‚ it triggers them to swell and can even cause them to burst ((Helmenstine

Introduction A. Background of the study Due to the overwhelming demand of plastic bag production and its effects on our environment‚ our landfills are crammed with these non biodegradable materials. Substances used in the manufacturing brought forth various harmful chemicals which worsen over time. As the destructive compounds such as Chloroflourocarbon were introduced‚ the complete deprivation of the Ozone Layer starts. However‚ scientists and nature preservers alike managed to overthrow this
