-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt‚ sugar‚ dirt‚ and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it‚ pouring water‚ vinegar‚ and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First‚ do steps (3-6)to find out the properties of salt‚ sugar

The effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis‚ there are two main parts‚ including light dependent and light-independent reactions. Plants use the energy from light for producing sugar‚ which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucose

water on the rate of photosynthesis. Aim: The aim is to investigate how increasing carbonate in water can affect the rate of photosynthesis. Introduction: The rate of photosynthesis can be increased or decreased in many different ways. For example‚ by adding substances like alkaline or salt to the water‚ you can increase or decrease the acidity or basics‚ if the water has too much acidity‚ it can often delay the rate of photosynthesis‚ often stopping the rate of photosynthesis in the plant‚ which

Phase Change Lab Ha Min Noh Ms. D Chemistry February 6‚ 2016 Question How does time relate to the change in temperature of H2O as it changes phases from ice to water to gas? Hypothesis If the time which H2O stays on the hot plate increases‚ then the temperature of H2O will increase and the phases from ice to water to gas will change because the heat is a source of energy to change the physical states. Background Ice is a solid form of H2O and water is a liquid form of H2O. The gas form of H2O

Biology (D) Ms. Wainman The relationship between Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration both ‚but animal cells

All green parts of a plant have chloroplasts. However‚ the leaves are the major site of photosynthesis for most plants. There are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll‚ the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2 enters

Photosynthesis and Cellular Respiration lab makeup Photosynthesis absorbs energy from the the sunlight ‚and water‚and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis

Hypothesis: The bigger the area‚ the larger species it can support. Aim: To see how the size of an area affects the relationship between species diversity. Diversity is a range of different elements. Habitat size determines diversity relationship(Edition of Nature‚ March 28 2002). In the research of specie diversity ‚ it was found out that more productivity was done when two different types of species were in one area. It was also said that diversity goes down but as it goes down the productivity
