AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because light intensity

Julie Smith 2/14/2017 Bio 220 Lab Report Learning How to Use the Compound Light Microscope Introduction: Microscope is an instrument used to grow pictures of little questions that are difficult to see with the unaided eye. The compound light magnifying instrument‚ which will be utilized as a part of this lab movement‚ is an instrument with two focal points and different handles to center the picture. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives:

student’s head and then hide the other two. Then‚ one at a time‚ the students would open their eyes‚ look at the other two students’ heads‚ and try to guess which color hat was on their own head. The students had two options. They could either to guess what color of hat they had on their own head or pass. If a student guessed the correct color of hat on their own head they would be exempt from any POW’s the rest of the semester‚ but if they guess wrong they had to do all of the POW’s as well as grading

Photosynthesis Lab Kozlowski Kendal Schweiss Hour 6 Introduction: Photosynthesis is carbohydrate production using light and chlorophyll. It is a process when green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen‚ using light energy trapped by chlorophyll. The rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. 2H2O + CO2 + light -> carbohydrate (CH2O) + O2 + H2O There is a spongy mesophyll

Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will

Examination of How Different Colours of Light Affect The Rate of Photosynthesis INTRODUCTION Plants are an essential part of the food chain required by all living things to survive. The growing world population and subsequent alteration to the natural environment has placed increased pressure on available plant resources. This is particularly evident in the area of agriculture‚ where optimum crop productivity is important to meet the increased demand for food by the growing world population

Historiographical Review (Whiteness of a Different Color) Throughout U.S. history race has proven time and time again to be a focal point of many countries’ issues and conversations. As time has changed so have the definitions of who is white. In Whiteness of a Different Color: European Immigrants and the Alchemy of Race‚ Matthew Frye Jacobsen argues that the idea of race and whiteness has changed rapidly in U.S. history because of the strength it holds to serve as tool of power. In short Jacobsen’s

To do the lab exercises for this lesson‚ you need to know a little bit about light. White light consists of all the colors of the rainbow mixed together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light that travels
