water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of Paramecium. Experiment Design The experiment prediction is if we add 4mL of Paramecium to 25mL of 0.2M NaCl and 225mL of Dryl’s solution‚ then Paramecium

Purpose: Can the penny hold more drops of water or more drops of the MYSTERY liquid? Research: Cohesion- The state of sticking together. Pennies can hold more water because soap reduces the cohesion of water and the water molecules break apart and can’t stay on the penny. Hypothesis: The penny will hold more a larger number of drops of water because water is more cohesive than the “mystery” liquids Variables: Independent variable: Penny Dependent variable: Number of Drops of Water Control

The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely

on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚ then they will regenerate stronger and faster. This is important because it could lead to faster regeneration for the animal and lead to bigger things such as finding a way to incorporate this to human regeneration. Many experiments have been researched

The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect

March 2013 Genetic Predictions in the Fruit Fly The Drosophila melanogaster is a fruit fly with a very short life cycle. They can be winged or wingless‚ and have red eyes or white eyes. The different options are called alleles. Alleles are the variants of a specific gene‚ and one is received from each parent on each chromosome. (“What Are Dominant and Recessive?”). It was chosen to use winged females and wingless males to predict the offspring in this experiment. The winged allele is dominant‚ meaning

AP Biology Fly Lab Write Up Make sure you obtained your F2 generation information from your group to complete the questions on your lab handout. I will be grading all of the tables and questions in your lab. Being able to write a null hypothesis will be extremely important in college so make sure to take your time and do it right ( Remember that the null hypothesis needs to be in an “If…then…because” format. • Ex. If I cross ___________then a ratio of ________should be expected because

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

Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

Materials and methods 1. Raw materials Full ripe cactus Opuntia dillenii fruits were harvested from the orchard of Faculty of Agriculture‚ Suez Canal University‚ Ismailia Governorate‚ Egypt during December 2014. Fruits were washed and glochides and the two distal parts (top and bottom parts) were removed. The fruits were mashed in a mixer by mixing for 15 s. After that‚ the seeds were separated‚ washed and dried by hot air in a convective dryer (WT-binder‚ Type F115‚ Germany) at 50 ºC‚ air velocity
