Internal Investigation: Exploration Juan Garcia 11/17/15 Period 2 Problem/Question What is the effect of varying pH solutions on the rate of photosynthesis on the Indian Lotus (Nelumbo nucifera) via The Floating Leaf Disc Assay? Background The Indian Lotus is an aquatic plant that is quite popular among cultures as being sacred. It is often used to portray beauty as it grows from the mud unstained and pure. It is also used today in many Asian foods. As such the growth of the Indian Lotus is one

The pH probe of the device was rinsed in distilled water between every measurement to return back the pH of the probe to a neutral pH, and between tests to avert cross contamination of solutions. This procedure was repeated two times for attaining Waterfall Gully, Johnston’s Creek and Port Adelaide River pH. The Dhaka water sample was tested via titration method which is used to measure the unknown concentration of a known reactant. This

technologies that recycle water, eating fresh produce in space, and the final landing on Mars a year later and watching the rovers that landed before him moving about. Many problems of space travel stem from the fact that supplies are limited in space. A trip to Mars with current technologies would take eight months to travel to Mars and that is just robotic missions (NASA 2012a). This presents an obvious problem that a space flight can only carry a limited amount of food, water, and air. Any system

The Relationship Between Density and Sugar Content Danielle Shaub Partners: Emily Alexander, Bill Dempsey, Shayla Ho Lab Performed 03/11/15 & Lab Report 04/07/15 Abstract: Using solutions of sugar and water alongside cola, density and percent sugar can be related. The purpose of this lab is to discover how and with what benefit these factors can be related. Using assorted measurements and the standard curve of the calculated densities and percentages of sugar solutions, it was learned that cola

cold, sunny day. The solar radiation that is coming in warms up the inside of the car, but the solar energy that is going out is trapped inside the car’s closed windows. Greenhouse gases are the gases in the atmosphere that absorb radiation, such as water vapor, carbon dioxide, methane, and nitrous oxide. Out of all these greenhouse gases, carbon dioxide is the primary gas produced due to the combustion of fossil fuels from electricity, transportation, and industrial

The Clean Air Act (CAA) is a law that regulates air emissions from mobile and stationary sources. This law is comprehensive federal that authorize the U.S Environmental Protection Agency (EPA) establish National Ambient Air Quality Standards (NAAQS) to protect people’s health and welfare and to regulate emissions of hazardous air pollutants (The United States Environmental Protection Agency EPA, 2015). The title I of the Clean Air Act (CAA) states the general requirements for states to submit Strategic

minerals break down or dissolve into smaller pieces and fragments. Erosion is then the transportation of weathering remains. This is done with the help of natural agents such as water, wind, animals..etc. It all depends on the composition of the rock, different agents such as temperature change and rainfall amount. Water for examples is the most common, like when it seeps in the pores of rocks, freezes overnight and

harsh on the environment has been going on ever since the United States has increased its use of this process to obtain more natural resources. Hydraulic fracturing is also directly correlated to having effects on drinking water. The process of fracking includes the injection of water containing other chemicals into the ground to extract natural resources that would otherwise be more difficult to obtain (Hydraulic Fracturing Overview, 2012). Although the process of fracking has resulted in an increase

Ah! A hot summer day and a cool can of soda. What could be better! But can you imagine my angst, when in spring break my Mom threw away all the Soda cans left over from the new year party. This got me thinking, so I challenged my mom and was chagrined when she said "Take a look at Berkeley, and why they passed the first Soda Tax in America" What follows is a chronicle of my 8 weeks of journey starting with scientific inquiry trysts in Cupertino library to meeting a Professor of nutrition at Stanford
