Investigating pH Aim: To demonstrate dissolved carbon dioxide changing the ph level of substances. Materials: * 2 beakers * 2 straws * Stop watch * Distilled water * Lime water * Litmus Paper Method: 1. Pour 100ml of Distilled water into the first beaker‚ and label said beaker. 2. Pour 100ml of Lime water into the second‚ also Label beaker. 3. Test the two liquids with litmus paper and note the ph level‚ before any carbon dioxide has been introduced. 4. Place a straw

Justification Paper Jim Lammers There is no disputing the fact that performance enhancing drugs have the potential to raise the level of competition in athletics. The goals in sport can be boiled down to higher‚ farther‚ and faster; therefore in order to improve competition it is necessary to make athletes bigger‚ faster and stronger. Professional athletes (not collegiate or interscholastic) should be allowed to make choices in their training regimen which will make them better prepared to do the

THE EFFECT OF PAPAYA EXTRACT IN SEED GERMINATION OF MONGO SEEDS I. INTRODUCTION The angiosperm‚ or flowering-plants‚ from the Greek word Angein means vessel or receptacle‚ makes up the most adundant and dominant group in the kingdom plantae. From grasses to cacti‚ from tiny herbs and wild flowers to large maple trees and oaks‚ considering all plants familiar to you are majority belongs to these group. (Moses‚ P.B.‚ Chua N-H‚ 1988) In angiosperms‚ flower is the crucial site where sexual reproduction

BIOLOGY GERMINATION EXPERIMENT INTRODUCTION: Germination is the resumption of growth of the embryo plant inside the seed. Requirements for germination: * proper temperature * the presence of adequate water * oxygen There are two types of cotyledons: the monocotyledons (“monocots”) and the dicotyledons (“dicots”). Monocots have one cotyledon. Rice and corn are monocots. Dicots have two cotyledons. Lentils‚ lima beans‚ and green beans are dicots.* Germination in Dicots 1

The Greenhouse Effect Rationale The “Greenhouse Effect” is a term that refers to a physical property of the Earth’s atmosphere. If the Earth had no atmosphere‚ its average surface temperature would be very low of about 18℃ rather than the comfortable 15℃ found today. The difference in temperature is due to a suite of gases called greenhouse gases which affect the overall energy balance of the Earth’s system by absorbing infrared radiation. In its existing state‚ the Earth atmosphere system balances

Consequences of greenhouse-effect temperature rises Predicting the consequences of global warming is one of the most difficult tasks for the world’s climate researchers. This is because the natural processes that cause rain‚ hail and snow storms‚ increases in sea level and other expected effects of global warming are dependent on many different factors. It is also difficult to predict the size of the emissions of greenhouse gases in the coming decades‚ as this is determined to a great extent by

2. Good governance – the concept In the last twenty years‚ the concepts of “governance” and “good governance” have become widely used in both the academic and donor communities. These two traditions have dissimilar conceptualisations. First‚ there is the academic approach‚ which focuses mainly on the study of the different ways in which power and authority relations are structured in a given society. Second‚ there is the donor community’s approach‚ which puts emphasis on the role state

Effect of Irradiation on the Growth and Germination of the Corn (Zea mays)¹ Mardocheo Yao Crispino S- 5L ¹A scientific paper submitted in partial fulfillment of the requirements in Biology 30 (Principles Of Genetics) laboratory under Mr. Jickerson P. Lado‚ 1st sem.‚ 2013-2014. ABSTRACT The effect of irradiation on the growth and germination of the corn was determined by planting ten seeds per treatment with varying doses. Four hills representing

The rate of germination didn’t really vary between the number of paper towels throughout the experiment. Most of the seeds had germinated in the paper towels. The one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My

The Effects of Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which
