Does Soap Affect the Surface Tension of Water? Background: Surface tension refers to water’s ability to "stick to itself". Surface tensioncan be measured and observed by dropping water (drop by drop) onto a penny. Thenumber of water drops that can fit on a penny will surprise you. Question: How does soap affect the water’s surface tension? Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds‚ and when water is mixed

Constellation In modern astronomy‚ a constellation is an internationally defined area of the celestial sphere. These areas are grouped aroundasterisms (which themselves are generally referred to in non-technical language as "constellations")‚ which are patterns formed by prominent stars within apparent proximity to one another on Earth’s night sky. There are also numerous historical constellations not recognized by the IAU or constellations recognized in regional traditions of astronomy or astrology

I. Introduction A. Area 51 is a top secret military base that wasn’t even considered to exist until 2013. Some people believe that UFO’s and alien objects are stored here‚ but this information cannot be proven. The content of area 51 today is unknown‚ but we do know what it was created for! I found most of my information on the internet and watching documentaries on this. B. Location 1. Located in the remote Nevada desert near the dry bed of Groom Lake‚ Area 51 may be the most famous military installation

WHAT IS AREA 51…. Introduction Area 51 is a military base‚ and a remote detachment of Edwards Air Force Base. It is located in the southern portion of Nevada in the western United States‚ 83 miles (133 km) north-northwest of Las Vegas. Situated at its center‚ on the southern shore of Groom Lake‚ is a large military airfield. The base’s primary purpose is undetermined; however‚ based on historical evidence‚ it appears to support development

ABSTRACT It is obvious that green areas and parks have enormous effects on the community or people who live in that neighborhood. Green spaces and parks help the children to have a playing area around the community which brings more comfort. Green spaces and parks beautify the community‚ create a pleasant environment for the people and protect the natural environment. The aim of this article is to investigate the effects of green areas and parks on people in Nicosia considering its influence on

Background Information Surface area will increase the speed of reaction as the greater the surface of the solid reactants‚ the more particles are required to expose and ‘cover’ the capacity of the solid. Increased surface area results in an increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or

Cities and suburbs was a sociology class where I have learned issues like suburbanization‚ neighborhoods‚ culture and poverty‚ gentrification‚ deindustrialization‚ segregation‚ downtown redevelopment‚ and housing. Not only did I learned what these terms mean‚ but also how they have affected us every day. Professor Rosenblatt has given my classmates and I a chance to apply our knowledge through a neighborhood project. The town that I picked was called Wheaton. Through my field research‚ I think the

Planning Aim To determine how the surface area of the tablets affects the rate of the reaction. To determine which form of tablets gives the biggest surface area resulting in the fastest reaction rate. Investigation question: What is the relationship between the total surface area of the tablets and the rate of the reaction? Hypothesis: The rate of reaction will be the fastest when the tablets crushed into powder as there is a bigger total surface area resulting in more effective collisions
