My Investigation on osmosis Osmosis is a special kind of diffusion. While diffusion can describe the movement of any kind of molecule‚ osmosis is only about the movement of water molecules. To show this diffusion I will be using potato discs‚ of the same size and mass‚ in different concentrations of sugar solution to find out whether the mass of the discs increases or decreases depending on the concentration. I predict that when the sugar solution is 0% the mass will increase as there is

HYDROGEN BONDING: Hydrogen bonding is a bonding type consisting of dipole and dispersion forces. A hydrogen bond is the attractive force between a hydrogen atom attached to a molecule and an atom of a different molecule. According to the Pauling scale of electro-negativities of the elements‚ it can be viewed that the three most electronegative elements in the periodical table are nitrogen‚ oxygen and fluorine. These are also called heteroatoms. The heteroatoms have a partial negative charge while

Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality

electronegativity separates 2 hydrogen atoms from catechol‚ oxidizing it and therefore converting catechol to benzoquinone molecules that forms long‚branched chains. The chains are the backbone of the red and brown pigments that cause darkening.

Summary of the chicken doesn’t skate The book is about a chicken that started as a science project and then changed into a people’s friend. For some people it was their mascot their school and for one person‚ DINNER!!!! It all started when the science teacher‚ Ms. Baggio and said “there will be a science fair in a couple of weeks”. All the children started to think about topics. Milo‚ a seventh grader decided to do his report on the food chain. Milo went and adopted a chicken for his project

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose
