The Cold Equations

Carol-Ann Dennis – Backward Planning Lessons 1-4 – Week 3 Title of Lesson 1: What is a chemical reaction? Grade Levels: 7th grade Standard: MS – PS1-2. – Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. (examples = burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride). Objectives: Students will be introduced to chemical reactions, reactants

Drought as a recurring extreme climate event can be defined from various perspective, including meteorological, hydrological, agricultural and socio-economic aspects. Materials and Methods Study area Iran has an area of 1,648,000 km2, is situated in the south-western part of Asia. The climate is influenced by Iran 's location between the subtropical humidity of the eastern Mediterranean area, the subtropical aridity of the Arabian desert areas and its topographical features like presence of the

evolved so much in admittedly not that long of a time. Imagine (if going back in time was possible) taking a cave-man to the present. Imagine how amazed he or she would be. Technology has made a great impact on humanity. In the short story “The Cold Equations” by Tom Godwin, the year is 2178. First of all, how do you perceive that number as a year? “ Galactic Expansion had followed the development of the hyperspace drive” (Godwin 10). How insanely awesome is that? Technology has helped the human race

Introduction: In day-to-day life it is very common to experience phenomenon’s involving heat or heat transfer. For instance, hand warmers used to warm fingers while skiing and ice packs used to reduce swelling of an injury, involve heat exchange. What is responsible for this heat exchange? Looking at thermochemistry may give an explanation. Thermochemistry is a branch of chemistry focusing on heat. Specifically, it studies heat released or absorbed in a chemical reaction. 1 Reactions

doubt learned much more in this class than I assumed I would, I still have trouble grasping the equations and backgrounds of the scientific discoveries we have read about. Science and math have never been my strong suits so it takes a little bit of extra explanation and breakdowns for me to fully comprehend lessons within the two. Since I am a visual learner, watching the theories, laws, and equations be proven would definitely be helpful for me. If there were videos incorporated into the lectures

The television series, Through the Wormhole had an episode that talked about the Subconscious of the human brain. The subconscious of the brain has long been thought of as the source of our primal fears and desires. Scientists have discovered how the subconscious makes snap decisions that protect us from harm, and that it can be trained to actually heal our bodies of disease. There was an example in the video where Morgan Freeman talked about when he was eight years old he had to memorize twelve

but no change was made. The overall framework of the big bang theory remains unchanged, but some details of the theory are still being modified today. For example, Einstein himself initially believed that the universe was static. But when his equations seemed to show that the universe was either expanding or contracting, Einstein added a constant term to cancel out the expansion or contraction of the universe. Then, when the expansion of the universe was later discovered, Einstein stated that adding

BACKGROUND Thermodynamics is concerned with energy changes that occur in chemical and physical process es. The enthalpy and entropy changes of a system undergoing such processes are interrelated by the change in free energy, ªG, according to the equation ªG = ªH - T ªS (1) This investigation focuses on the reaction Zn(S ) +

National University of Singapore CM1501 Organic Chemistry for Engineers Lab Report Experiment 2: Separation and Identification of Two Organic Compounds 10th October 2013 Abstract This experiment involves the separation and identification of 2 organic compounds (1 Neutral Compound and 1 Acidic Compound) in a mixture. Separation techniques used in this experiment include solvent extraction, simple distillation and recrystallization using a suitable solvent determined through a solubility
