The Effects of ECB on Corn Crop Yield Abstract In this experiment we explore the infestation of ECB (European Corn Borer) on different types of corn and how it effects the corn crop yield. The corn is grown in a controlled environment with the only changing variables being the type of corn and the concentrations of the infestation of the ECB. Varying levels of infestation are tested on a corn crop throughout a 140 day growing season‚ at the end of the season the crops are then measured for

Alka-Seltzer Reaction Rates Lab What are the different factors the effect the reaction rate of Alka-Seltzer? Matthew Arkfeld Leah Gilligan Jessie Abbott Period 4 June 2nd‚ 2008 Background Research: o The objective of the experiment was to determine if different factors affect the reaction rate of Alka-Seltzer. Alka-Seltzer provides fast relief to acid indigestion‚ upset stomach‚ heartburn‚ headaches‚ body aches and pains. It is an antacid and pain relief medicine used by millions

in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease in weight as the concentration increases. The independent variable in this experiment would

goldfish’s metabolic process at two different temperatures a chamber and Logger-Lite‚ computer software‚ were used during this lab. However‚ only data from lab section 1F was analyzed for this report. The goal was to determine if the goldfish’s metabolic rates‚ as measured by oxygen consumption‚ will increase when the water temperature is moderately warm. Alternatively‚ the metabolic rates of goldfish‚ as measured by oxygen consumption‚ will not differ between warm and ambient temperatures. Materials and

Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths

Caffeine effect on Daphnia’s heart rate Prepared for: Androniki Kloni By: Maria Mitsi October 6‚ 2013 Abstract Caffeine is a bitter‚ white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants‚ as well as enhancing the reward memory of pollinators. An experiment was held‚ on an aquatic

TM How Does Temperature Affect Daphnia Heart Rate? Student Study Guide DID YOU KNOW? The body temperature of the Arctic squirrel drops from 98.6°F to 26.4°F‚ which is below the freezing point of water and is the lowest known body temperature of any living mammal. DID YOU KNOW? The average body temperature of the following warmblooded animals are: Humans: 98.6°F Rabbit: 101.3°F Polar bear: 99.1°F Blue whale: 95.9°F Owl: 104.4°F Ostrich: 102.6°F BACKGROUND Every animal

observe the effect that the concentration of hydrochloric acid (independent variable) has on the rate of reaction (dependent variable) between the magnesium ribbon and the hydrochloric acid. Hypothesis As the concentration of hydrochloric acid increases‚ the time taken for the magnesium to disappear will decrease. (The greater the concentration of hydrochloric acid‚ the faster the reaction between the magnesium and hydrochloric acid will occur.) In addition‚ doubling the concentration of hydrochloric
