Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

Virtual Lab: Optimizing Photosynthesis Maria Diaz March 12‚2012 Pre-Lab Questions 1. Which two variables are controlled in a similar manner? The two variables that can be controlled in a similar manner are CO2 & the light level. 2. How can you get the results to the investigation faster? You can get the results to the investigation faster by adjusting the speed at the bottom of the water weed simulation. 3. How will you be able to determine the rate of photosynthesis

such as the red maple were located in stations four and five. It was noticed that the area in which bunchberry plants grew were shady areas because the large trees were blocking the sun light from reaching them. Plants need sunlight to conduct photosynthesis in order for growth to take place; however‚ too much exposure to the heat the sun brings may cause a plant to become too dry through the process of evaporation which supports the earlier prediction that a bunchberry requires a moist‚ cool environment

Photosynthesis Lab Gizmo website: www.explorelearning.com Class code: EFVNHTVRGY Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it is released. In the Photosynthesis Lab Gizmo™‚ you
