Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab‚ I will study how digestion of carbohydrates‚ proteins‚ and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical

“what is destroying the ocean?”. Well one of the many answers is microplastic. Microplastics are little pieces of plastic that are smaller than 5 millimeters. Microplastic is harming zooplankton in many ways ‚ but not only zooplankton a lot of other fish also in many ways. When people leave plastic on the ground it eventually makes its way to the ocean . Microplastics are thrown into the ocean by people which is causing fish to die. There is a lot of microplastic in the ocean which is a serious problem

church‚ the age of the earth was 6‚000 years old. 2. James Hutton discovered that the earth was much older from the tilted rocks because he knew these rocks was once laid down horizontally on the sea floor and were buried under great depth to be crystalized. Then they were tilted on end by great earth forces and then eroded away. The rocks were then deposited on top. He understood it had to take millions of years for this process to happen. 3. Lord Kelvin calculated the earth to be around 20 million

Earth Science is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science‚ the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere‚ hydrosphere‚ oceans and biosphere‚ as well as the solid earth. Typically‚ Earth scientists will use tools from physics‚ chemistry‚ biology‚ chronology and mathematics

wonder how are they going to end. There has been many speculations involving earthquakes‚ tsunamis; meteors‚ and even a second ice age. But is it the end closer than we thought? In the past 100 years‚ the human race has developed tremendously. The use of chemicals‚ such as gasoline are bringing pollution to the earth atmosphere. This is making the temperatures higher. And it’s affecting the planet in many ways. Antarctica‚ the world greatest freezer is melting. And as it turns out the ocean levels

The Battle of Anorexia One CBS News story written by Daniel Schorn tells the story of Kennedy Pieken‚ a girl who was just four years old when she began battling the effects of anorexia. Doctors at the Omaha Children’s Hospital suggest that her eating disorder was triggered by changes in her brain that occurred after she suffered strep throat. It was suspected that the trigger was present through genetics because her mother‚ Jodi Pieken‚ spent

natural riches and a beautiful environment that would serve as our home. We are so secure‚ safe and well-nourished within Mother Earth’s womb. However‚ we never saw the real extent of how precious this planet is to us and we went out the world as a successful species but completely a failure as sons and daughters of Mother Earth. Instead of protecting and nurturing the environment‚ we did just the opposite. We built factories that release substances that destroy the environment and kill many animals‚ we

scales is the result of the interaction between physical‚ cultural and economic and behavioural factors. Farming in Great Britain has been characterized by technological changes in recent decades which has led to massive increases in yields and improved stock rearing. Much of this change is due to the application of scientific research in plant and stock breeding and improved mechanization. But even today agriculture relies heavily on the physical environment. All crops require a specific range

Why do I do it? Why do I scare myself with the ocean…? It is true‚ it is merciless‚ literally; it’s not conscious‚ so it has no feelings‚ no remorse‚ no pity‚ no awareness. It would be wrong to say it is inanimate‚ because it is certainly animate. And not alive‚ yet contains so much life within it might as well be. Like a Frankenstein body filled with cells and bacteria and nerve impulses yet no consciousness. My worst nightmare – I don’t have it very often but it’s a strong one – can take
