How to float an egg in the middle of water? Objective: To understand how density works and how you can change the density of a liquid. Materials Needed: Procedure: 1) Fill 3 glasses with 250ml of water and place a fresh egg in one of the glasses‚ watch as it sinks. 2) Put 4 tsp. of salt into one of the glasses stir it up and place an egg in the water. Watch as it floats. 3) Put 4 tsp. of salt into the final glass stir it up and pour out some of the salt water. Now place an egg

“Acid Rain” Environmental science What is Acid Rain? Acid rain is a rain or any other form of precipitation like rain‚ fog‚ snow‚ or hail that contains harmful substances higher than normal amounts of such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs

NASA laboratories lead to new technologies that improve astronaut health and monitoring‚ while making scientific discoveries that benefit life on Earth. Another amazing that thing that space exploration has done for people on Earth is help make huge strides in the continuing development of artificial limbs. These are for people who have lost either

Introduction This experiment was designed to discover the how paper and other materials burned. The research question is: “What added material makes paper burn fastest?” My hypothesis was that gasoline would burn up the fastest. The experiment includes soaking toilet paper squares in various materials and burning them to see which burns the best. Research Paper itself burns well‚ that is a common known fact. Gasoline‚ rubbing alcohol‚ and petroleum jelly also are widely known as highly flammable

the spray’s upward motion. Top | Method: A meter stick was suspended directly above the rim of a 2 liter Diet Coke bottle. This was so we could measure the spray (in inches) once the Mentos were dropped into the soda. We constructed a paper funnel to drop the Mentos into‚ in order to make sure all the drops were uniform and that all the Mentos went in. We dropped the Mentos into the cola and‚ while filming the reaction‚ measure the spray height‚ using the meter stick. We started with

CHAPTER III MATERIALS AND METHODS This research study used the process of extraction to test the effectiveness of Acapulco (Cassia Alata) leaves in killing or eradicating the fungi Microsporum canis. The raw material that the researchers used in the experiment is the Acapulco with the scientific name Cassia Alata. It belongs to the family of Leguminosae. It is a shrub which is erected and grew for about 2 meters tall. The leaves of the plant posseses fungicidal‚ insecticidal and pesticidal

Why do boats float? All boats float‚ but floating is harder and confusing than it sounds and its best explained through a scientific concept called buoyancy. Buoyancy is the force that causes floating. An object will either float or sink depending on its density in the water. If it’s denser than water‚ it mostly sinks; the less dense object usually will float. It doesn’t matter the size of the object is. Plastic that is big as a football field will float because it is less dense that the water. A
