Samantha Meyer Lesson Plan 8/Reflection #8 SCIE 376 This week‚ I taught a lesson about fingerprinting to my students and it went extremely well. The students were highly attentive‚ every student participated‚ and based off of my assessment‚ every student fully understood the topic. My lesson this week aligned with the scientific and engineering practices 1‚ 2‚ and 4. Practice 1 is asking questions‚ practice 2 is developing and using models‚ and practice 4 is analyzing and interpreting data. My

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted

STRUCTURE OF DNA Structure of DNA University Of Phoenix Principles of Biology BIO/101 Phil Clifford January 13‚ 2009 Structure of DNA Since the beginning of human history‚ people have been intrigued how traits are inherited from one generation to the next. What is DNA? DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus (called nuclear DNA)‚ but a small amount of DNA can also be

IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s

follows; 6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂1 There are four variables that affect the rate of photosynthesis; light intensity‚ temperature‚ CO₂ and water.2 However‚ is it possible to count in the colour of light‚ too‚ which I am going to investigate in this lab. Since the photosynthesis takes place in chloroplasts that has chlorophyll‚ the rate of photosynthesis can be affected by different colours of light‚ since the absorption of light changes within different colours. Research Question: What colour of

“Comparing Average Rates of Respiration in Mealworms in Light and Dark Environments in a Manometric System” Mohammad Rafi 213552179 BIOL1000 LAB REPORT Oct 28‚ 2014 Hypothesis The biological hypothesis for this lab experiment was that the rate of respiration in mealworms would decrease in mealworms that were exposed to a dark environment compared to those mealworms that were exposed to a light environment. This hypothesis was based on the fact that oxygen levels tend to decrease in

The amazing advances in health science‚ DNA is transforming the way in which criminal investigations and trials are carried out. DNA evidence and its importance can rest on a single fact: Every individual’s DNA is unique. A person’s DNA profile can be used similar to a fingerprint to link suspects to crime scenes and its victims. DNA profiling—which is also called DNA fingerprinting or even DNA typing—has been responsible for overturning verdicts and saving innocent people from execution. The process

The Reliability of Forensic Science Your DNA is split into two halves one from you mom and one from your dad‚ nobody has the same DNA as you unless you are a identical twin or a clone. Your siblings have different DNA than you though you have the same parents because the two halves combine differntly. In the year of 1984 Alec Jeffreys discovered the use of fingerprinting in a case. Since this discovery this tool has solved many cases and help with the falsely accused victims get out of the trouble
